- the molding apparatus 25 Although intension is made to impart a three dimensional shape by the molding apparatus 25 on the surface of the bag 10 manufactured using the packaging film 11 constituted only of the above mentioned basic structure, by itself, it is difficult to realize the three dimensional designs with excellent appearance. Therefore, it is necessary to additionally provide the structure for developing the effect by the molding apparatus 25 of the above mentioned (1) to (4). Or, it is preferable to provide the additional structure for further developing the effect by the molding apparatus 25 of the above mentioned (1) to (4). To be specific, when imparting the three dimensional designs by (1) the heater and (2) the light irradiation apparatus, the printing layer 19 of the packaging film 11 needs to include foamable inks.
- the reinforcement sheet 14 is laminated in the inner side (sealant layer side) of the packaging film 11 or the sheet for three dimensional designs 15 is laminated in the outer side (substrate layer side) of the packaging film 11. Further, both of the reinforcement sheet 14 and the sheet for three dimensional designs 15 may be laminated on the packaging film 11. Moreover, when imparting the three dimensional designs by (4) the pressing machine, aside from the packaging film 11, the three dimensional sheet 16 is required in which the three dimensional designs are formed by the mold beforehand.
- the printing layer 19 is a layer for providing letters and patterns on the outer surface of the packaging bag.
- the printing layer 19 can be formed by using the publicly known printing methods such as screening printing methods and the like. It is necessary that the printing layer 19 is in the outer side than the opaque barrier layer 17.
- the substrate layer 13 is prepared as a double-layered film structure, one film of which is subject to the printing by a known printing method such as screen printing and the like, and the other film of which is subject to the formation of the barrier layer 17 by such methods as vapor deposition method and the like, thereby capable of laminating the both films to form the substrate layer 13 so that the printing layer is in the outer side.
- foamable inks are contained as inks used for the printing layer 19.
- Foaming agents are contained in foamable inks.
- the foamable inks the commercially available foamable inks can be used.
- the foaming agents for example, other than the thermally decomposable chemical foaming agents such as azodicarbondiamide and azobisisobutylonitrile, the thermally expanding microcapsule forming agents with hydrocarbon with a low boiling point enclosed can also be used.
- Matsumoto microspheres F-30, F-50, F-80S, and F-85 can be exemplified.
- no problem occurs when no foaming agents are contained but the gas generated by oxidation and decomposition by laser light is contained.
- foamable inks are used compounding 5 parts by weight of ammonium bicarbonate as the foaming agents in the ink constituted of 5 parts by weight of zeolite, 5 parts by weight of oxidative polymerization products, and 90 parts by weight of alkyd resin varnish.
- microcapsule foaming agents for example, such microcapsules can be used in which the surface of the core material that evaporates or generates gas by heating is coated with a shell wall of a resin that hardly allows the air passage.
- the foamable inks that contain microcapsules provide three dimensional unevenness on the surface of the packaging film 11 by the heater or the light irradiation apparatus for the core material evaporates (or generates gas), expands, and breaks the shell wall, thereby leaving the broken traces of the foamable inks on the substrate layer 13 that contacts with the printing layer 19.
- FIG. 5 A schematic sectional view is shown in Fig. 5 as an example of the structure of the packaging bag 10 when the three dimensional designs are formed by letting the printing layer contain the foamable inks.
- the structure of the layer of the bag 10 shown in the Fig. 5 is, starting from the inner side, the sealant layer 12/the adhesive or a polyethylene layer 18/the substrate layer 13/the barrier layer 17/the adhesive 18/the printing layer 19/ the substrate layer 13.
- a reinforcement sheet 14 is further laminated on the inner surface (sealant layer side) of the packaging film 11 in addition to the basic structure of the packaging film 11.
- the reinforcement sheet 14 is a layer for reinforcing the portion of the packaging film 11 subject to the three dimensional designs from the back surface in order to apply the three dimensional design decoration to the bag 10.
- materials with a thermoplastic property are selected as materials with a high retaining shape property under a room temperature and with light weight. In other words, at the time of embossing the packaging film 11, the three dimensional designs can be easily imparted by heating while when cooled to the room temperature, the three dimensional designs have a relatively high retaining shape property.
- thermoplastic resins such as polyethylene or polypropylene can be exemplified.
- the thickness of the reinforcement sheet 14 is 30 to 200 ⁇ m. When the reinforcement sheet is too thin, the effect of providing the three dimensional decoration to the surface of the packaging bag is not satisfactory enough, while on the other hand, when the reinforcement sheet is too thick, since the reinforcement sheet 14 is partially formed on the packaging film 11, it gets difficult to form the packaging film 11 in tubular and the process passing capability is likely to be disrupted.
- the reinforcement sheet 14 can be laminated by bonding to the packaging film 11 with general structures by adhesives and the like. However, bonding the reinforcement sheet over the whole surface of the packaging film 11 is not applicable since it becomes difficult to vertically seal or horizontally seal the packaging sheet film 11. In other words, it is necessary that the sealant layer 12 is provided to the outermost surface of the inner side of the portions subject to the vertical sealing or horizontal sealing of the bag. Therefore, in the present invention, when the reinforcement sheet 14 is provided, lamination is performed within the range that includes the range where the three dimensional designs are formed and that excludes the sealed range. In other words, it is preferable that the three dimensional designs for the bag 10 of the present invention is performed at predetermined portions within the range where the reinforcement sheet 14 is laminated in the inner side surface corresponding to the outer side surface of the bag 10.

- As types of the bag making-packaging apparatus used for forming the packaging bag from the aforementioned packaging film, both vertical and horizontal may be used. The present invention is hereby explained in the present specification taking the vertical packaging machine as an example. As a driving form of the packaging apparatus, an intermittent type is preferable to a continuous type since it is easier to form three dimensional designs by a mold in a static state.
- An example of a general vertical packaging machine is shown in
Fig.11 . The vertical bag making-packaging machine for vertical packaging is generally constituted of a former 23 for molding thepackaging film 11 supplied from a roll (not illustrated) into tubular, a pull-down mechanism 24 for forwarding the tubularly shapedpackaging film 11 downward along the former 23, avertical seal mechanism 21 for sealing the overlapped portions of thetubular packaging film 11 in the length direction on the former 23, and a pair ofhorizontal seal mechanisms 22 for horizontally sealing the vertically sealedtubular packaging film 11 at predetermined intervals. - Former 23 is a guide for placing the
packaging film 11 along and is constituted of ashoulder portion 23a with a curved surface and atubular portion 23b with a tubular shape. A pull-down apparatus 24 is an apparatus for forwarding the tubularly formedpackaging film 11 downward along the former 23. The pull-down apparatus 24 is generally constituted of abelt 24c and a plurality ofrollers - A
vertical seal mechanism 21 is a mechanism for sealing by overlapping the end surfaces in the length direction of a tubularly formedpackaging film 11. It is general that thevertical seal mechanism 21 is provided with a heating belt and a heating roller. On the other hand, ahorizontal seal mechanism 22 is a mechanism for horizontally sealing the vertically sealed tubular packaging film at predetermined intervals. Since the molding of the three dimensional designs to thepackaging film 11 is more easily conducted when performed intermittently by a mold 26 in the present invention, it is preferable to perform seal formation by thevertical seal mechanism 21 and thehorizontal seal mechanism 22 as well in accordance with the timing. One of thehorizontal seal mechanisms 22 has a knife for cutting the packaging film vertically and the other is provided with a groove to receive the knife and after sealing thepackaging film 11, it is cut vertically and the bottom portion of the next bag is formed as well as letting the formed bag fall downward. - In the bag making-packaging
machine 20 of the present invention, in addition to the mechanism of the general packaging machine as shown inFig.11 , the tubular former 23 has themolding surface 30 for forming the three dimensional designs at any position on the former surface and also, themolding apparatus 25 for forming the three dimensional designs to thepackaging film 11 is arranged at the position opposed to the molding surface of the former. In other words, thepackaging film 11 that reaches themolding surface 30 along the former surface is provided three dimensional designs by themolding apparatus 25. - In
Figs.1A and 1B , in order to show the positional relationship of themolding surface 30 and themolding apparatus 25 of the former 23 in the bag making-packagingmachine 20, the schematic side view (Fig.1A ) and the schematic sectional view (Fig.1B ) taken along the line X-X' are shown. In the general bag making-packagingmachine 20, since thevertical seal mechanism 21 is at the front side of the former 23 and the pull-down mechanism 24 is at the both lateral sides of the former 23, themolding surface 30 is preferably provided at the rear side of the former 23 as shown inFig.1A . Such arrangement allows the formation of the three dimensional designs at predetermined portions. As shown inFig.1A , it is preferable that themolding surface 30 with which themolding apparatus 25 contacts is plane. - Since in many cases register marks are printed at predetermined intervals in the
packaging film 11, it is preferable that the bag-makingpackaging machine 20 of the present invention is provided with a positioning mechanism utilizing the register marks that are printed on thepackaging film 11 in order to form the three dimensional designs at the accurate positions of thepackaging film 11.
Basically, the positioning mechanism is constituted of asensor 27A for detecting the register marks of thepackaging film 11, a movingmechanism 27B for moving themolding apparatus 25, and acontrolling mechanism 27C for controlling the movement. By providing such a positioning mechanism, the movement of themolding apparatus 25 can be controlled. The register marks need not be detected for thecylindrical packaging film 11 placed along the former 23 but can be detected for theplane packaging film 11 before the introduction of the former 23 as shown inFig.1A . - The moving
mechanism 27B is a mechanism for making themolding apparatus 25 contact with or separate from thepackaging film 11 positioned at themolding surface 30 of the former 23. To be specific, as shown inFig.2 , a shaft attached to themolding apparatus 25 moved back and forth by an air cylinder that is the movingmechanism 27B can be shown. Themolding apparatus 25 can be moved by introducing air to one of the two air introducing openings 27BA and 27BB and by exhausting the air from the other.
In addition, as the other mechanism, themolding apparatus 25 can also be moved by passing a screw shaft attached to the heater through a bearing of an apparatus frame thereby moving the shaft back and forth by the normal and reverse rotation of a motor. - The
sensor 27A is for detecting the eye marks of thepackaging film 11 and outputting a detection signal to the later mentioned controllingmechanism 27C. The controllingmechanism 27C moves the movingmechanism 27B so that themolding apparatus 25 contacts with thepackaging film 11 positioned on themolding surface 30 of the former 23.
In order to surely detect and precisely position the location to provide the three dimensional molding, it is preferable that thepackaging film 11 is provided with eye marks that can be sensed by a sensor at appropriate intervals. The eye marks are not necessarily visible and for example, when thesensor 27A of the eye marks is infrared ray sensor, it may be the eye marks provided by infrared ray absorbing inks. Also, as long as the eye marks can be sensed by thesensor 27A, they need not be present on the outer surface of thepackaging film 11, and chemical compounds that can be the eye marks may be included in aprinting layer 19. - The controlling
mechanism 27C is a mechanism that commands a series of operations of making themolding apparatus 25 contact with the outer surface of thepackaging film 11 positioned on the molding surface thereby firmly embossing the three dimensional designs for a certain period of time by themolding apparatus 25, followed by separating themolding apparatus 25 from thepackaging film 11. - As specific examples of the molding apparatus, the following apparatus (1) to (4) can be exemplified.
- (1) heater
- (2) light irradiation apparatus
- (3) mold
- (4) pressing machine
- A heater that is one of the
molding apparatus 25 foams foamable inks included in theprinting layer 19 by heating the predetermined portions where theprinting layer 19 of thepackaging film 11 is present in order to form the three dimensional designs at the time that thepackaging film 11 that runs along the former 23 reaches themolding surface 30. In the present invention, the heater is provided at a position opposite to themolding surface 30 of the former 23 and heats thepackaging film 11 from the outer surface (from the side of the substrate layer) . The heating surface of the heater has a shape that corresponds to the three dimensional designs to be formed. - The light irradiation apparatus that is also one of the
molding apparatus 25 can be used taking the same role as that of the heater. When the foamable inks included in theprinting layer 19 of thepackaging film 11 have a property of foaming by the specified wavelength of light, the light irradiation apparatus is used more preferably to the heater is. - The mold 26 can also be used as the
molding apparatus 25. InFig. 3 , the schematic view of the mold 26 used in the present invention is shown. As molding methods by the mold 26, any of vacuum molding, air pressure molding, pressing molding, or emboss molding that are used in plastic molding are applicable. When the three dimensional designs are provided to thepackaging film 11 using the mold 26, it is preferable to use the mold 26 that is constituted of amale mold 26A and afemale mold 26B with a shape engaged with the shape of themale mold 26A and use one of them for themolding surface 30 of the former 23, although onlythemoldingapparatus25canbeusedasamold26 (hereinafter, indicated simply as "male 26A" and "female 26B"). - The controlling mechanism controls the movement of the female 26B based on the detection signal of the register mark of the
packaging film 11 and by this, the three dimensional designs are formed on the packaging filmpositioned at themolding surface 30. Further, it is preferable that the female 26B is provided with a vacuum apparatus such as ablower 26C for depressurizing the space between both molds when the male 26A and the female 26 B are engaged. It is preferable that the female 26B is provided with a moving, pressurizing mechanism so as to emboss (pressurize) thepackaging film 11 with the movement of the female 26B. When the male 26A and the female 26B are engaged, the space between the molds is made into a depressurized state by theblower 26C, and in molding, it is preferable that a heater is embedded in the female 26B so as to make the three dimensional designs more beautiful. In this case, the female 26B is molded after heated to an appropriate temperature beforehand. As the moving, pressurizing mechanism, such a method of positioning the female 26B toward and away from the male 26A either by driving the shaft that supports the female 26B by an air cylinder method or by changing the relative positions to the frame by engaging the screw of the shaft with the screw of the frame and rotating the shaft by a motor. A flow sheet is shown in Table 1 in which female 26B is heated and is moved toward the male 26A thereby molding is conducted with a depressurized state between the molds. - The
pressing machine 29 can also be used as themolding apparatus 25 . Thepressing machine 29 is a mechanism for bonding the threedimensional sheet 16 with the three dimensional shape provided by using the mold 26 to thepackaging film 11. A schematic view of thepressing machine 29 and theadhesive laminate apparatus 29A is shown inFig.4 . - It is preferable that the
pressing machine 29 is provided at a position opposite to the former 23 of the bag making-packagingmachine 20. When the threedimensional sheet 16 is bonded to theplane packaging film 11 before introduced to the former 23, defects such as collapses of the three dimensional designs and the like are likely to occur when thepackaging film 11 is deformed into cylindrical along the former 23. - In the producing method in which a
sealant layer 12 or a hot melt adhesive 16A are formed beforehand at a back surface of the threedimensional sheet 16 and the three dimensional sheet is heated thereby bonding is made, it is preferable that thepressing machine 29 is provided with a heating plate (not illustrated) capable of pressing down the threedimensional sheet 16 at predetermined portions and heating the threedimensional sheet 16 as well. In the heating plate, a heating mechanism is built in. The heating plate is capable of heating the threedimensional sheet 16 by the contact of the threedimensional sheet 16 and thepackaging film 11 even before the threedimensional sheet 16 and thepackaging film 11 contact with each other. In the step where the threedimensional sheet 16 contacts with thepackaging film 11 thereafter, since the sealant layer or the hot melt adhesive has strong bonding force, both can be integrated to a full extent even if the contact time period of the threedimensional sheet 16 and thepackaging film 11 is short. In addition, inFig.4 , black surfaces on thepackaging film 11 show the predetermined portions to which the three dimensional sheet is bonded. - In the producing method in which the melted hot melt adhesive is laminated on a surface of the
packaging film 11 in the process right before the threedimensional sheet 16 is bonded by the pressingmachine 29, followed by bonding the threedimensional sheet 16 thereby integrating both while the hot melt adhesive is melted, the bag making-packagingmachine 20 can be provided with theadhesive laminate apparatus 29A for laminating a further melted hot melt adhesive at predetermined positions of thepackaging film 11 by such methods as spraying, coating, or the like. Black surface on thepackaging film 11 inFig.4 show the portions on which the hot melt adhesive 16A is sprayed or coated.
It is preferable that the spraying-typeadhesive laminate apparatus 29A is provided with a storage portion (not illustrated) for storing the hot melt adhesive, a heating mechanism (not illustrated) for melting the hot melt adhesive, and a nozzle (not illustrated) for spraying the melted hot melt adhesive.
In addition, it is preferable that a moving mechanism (not illustrated) is provided as is thepressing machine 29 so as to be close to thepackaging film 11 on the surface of the former 23 only at the time of spraying or coating. When the moving mechanism is provided, for determining the accurate positions for spraying, as is the case of the bonding mechanism, theadhesive laminate mechanism 29A can be controlled.
By the producing method of this embodiment, both thepackaging film 11 and the threedimensional sheet 16 can be integrated to a full extent even if the contact time period for the two is short since the hot melt adhesive is subject to heating in the storage portion beforehand. - A basic structure provided at least with the
packaging film 11 used for the bag making-packagingmachine 20 of the present invention has thesealant layer 12 of the inner side surface and thesubstrate layer 13 of the outer side surface. Further, in order to enhance the sealing property of thebag 10 produced with the bag making-packagingmachine 20 of the present invention, it is preferable to provide thebarrier layer 17 between thesealant layer 12 and thesubstrate layer 13. In addition, from a commercial view point, theprinting layer 19 is provided at a position visible from the outer side of thebag 10 such as the outermost layer of thebag 10, for example. - Since it is preferable that the
sealant layer 12 is melted under a low melting point (not higher than 160°C, and preferably not higher than 120°C), through a common procedure, a cast polypropylene (CPP) is used for thesealant layer 12 of thepackaging film 11 used in the present invention, however, a heat-sealable biaxial oriented polypropylene (OPH) can also be used. It is preferable that a heat-sealable layer of a cast polypropylene and a heat-sealable biaxial oriented polypropylene is formed by a copolymer of propylene and other olefin (ethylene, butane, and the like) or that a layer that includes low density polyethylene (straight-chain low density polyethylene and the like polymerized by metallocene catalyst) and an ethylene-vinyl acetate copolymer is formed on a cast and biaxial oriented polypropylene so that they can be melted at a low temperature. In addition, thesealant layer 12 may also be formed not only of polyolefin but also of polyester with low melting point. As polyester with low melting point, copolymerized polyester of ethylene terephthalate and cyclo hexanediol of EASTMAN KODAK CO. can be exemplified.
Also, as a film for thesealant layer 12, the one with the polymers with a high melting point (biaxial oriented polypropylene and biaxial oriented polyester) laminated on the above mentioned polymers with a low melting point may be used. As thickness of such asealant layer - As aforementioned, it is preferable that the
packaging film 11 used in the present invention has anordinary barrier layer 17 formed by vapor depositing metals such as aluminum, iron, magnesium, and the like or by vapor depositing ceramics such as silicon oxide and the like. As a thickness for thebarrier layer 17, in view of a light blocking property and an oxygen-water vapor blocking property, not less than 300Å is preferable and the thickness is selected among 300 to 1500Å. Thebarrier layer 17 formed by the method of this vapor deposition and the like can be formed on either of the surfaces of the substrate layer side of thesealant layer 12 or of the sealant layer side of thesubstrate layer 13. When thebarrier layer 17 is formed on the surface of the sealant layer, it is preferable to laminate the polymer layer as the material used for thesealant layer 13 on the polymer layer with low melting point with the former having higher melting point than the latter and to form thebarrier layer 17 in the polymer layer side with high melting point by such methods as vapor deposition and the like. Also, thebarrier layer 17 may be formed not of the above mentioned vapor deposited layer but of an ethylene vinyl alcohol film or a film that includes reduced iron or cobalt in combinations with the vapor deposited layer. - Since the
substrate layer 13 is a main constituent that forms thebag 10, thesubstrate layer 13 is required to have high tensile strength and appropriate hardness as well as to have a heat resistant property durable for heat seal at the time of forming bags, and it is preferable that the substrate layer is constituted of a biaxial oriented polypropylene film (OPP) and of a biaxial oriented polyester film. In addition, when a heat-sealable property is also required for the outer surface of thebag 10, a sealant layer is further formed on the outer surface of the OPP film or of the biaxial polyester film or a heat-sealable biaxial oriented polypropylene film (OPH) or a heat-sealable biaxial polyethylene terephthalate film is used. As thickness of the substrate layer, the range of 15 to 50µm is preferable. - When the
sealant layer 12 and thesubstrate layer 13 are laminated, thepackaging film 11 is obtained. As methods for laminating, dry-lamination laminating with an adhesive interposed or sandwich-lamination laminating by extruding polyethylene between both layers at a thickness of around 10 to 30µm can be exemplified. Asadhesives 18 used for lamination, two-liquid solution whose main ingredients are polyether and polyurethane, adhesives with the polymer of aromatic polyether series, aromatic polyester series, aliphatic polyester series, aliphatic polyurethane series, aliphatic polyether series dissolved in the solvent, and theadhesives 18 of hot melted type such as copolymer of ethylene acrylic acid, copolymer of ethylene methacrylate, copolymer of ethylene acrylate, and the like can be used. - Although intension is made to impart a three dimensional shape by the
molding apparatus 25 on the surface of thebag 10 manufactured using thepackaging film 11 constituted only of the above mentioned basic structure, by itself, it is difficult to realize the three dimensional designs with excellent appearance. Therefore, it is necessary to additionally provide the structure for developing the effect by themolding apparatus 25 of the above mentioned (1) to (4). Or, it is preferable to provide the additional structure for further developing the effect by themolding apparatus 25 of the above mentioned (1) to (4).
To be specific, when imparting the three dimensional designs by (1) the heater and (2) the light irradiation apparatus, theprinting layer 19 of thepackaging film 11 needs to include foamable inks. In addition, when imparting the three dimensional designs by (3) the mold, it is preferable that thereinforcement sheet 14 is laminated in the inner side (sealant layer side) of thepackaging film 11 or the sheet for threedimensional designs 15 is laminated in the outer side (substrate layer side) of thepackaging film 11. Further, both of thereinforcement sheet 14 and the sheet for threedimensional designs 15 may be laminated on thepackaging film 11.
Moreover, when imparting the three dimensional designs by (4) the pressing machine, aside from thepackaging film 11, the threedimensional sheet 16 is required in which the three dimensional designs are formed by the mold beforehand. - The
printing layer 19 is a layer for providing letters and patterns on the outer surface of the packaging bag. Theprinting layer 19 can be formed by using the publicly known printing methods such as screening printing methods and the like. It is necessary that theprinting layer 19 is in the outer side than theopaque barrier layer 17. In order to arrange the printing layer in the outer side than thebarrier 17, for example, thesubstrate layer 13 is prepared as a double-layered film structure, one film of which is subject to the printing by a known printing method such as screen printing and the like, and the other film of which is subject to the formation of thebarrier layer 17 by such methods as vapor deposition method and the like, thereby capable of laminating the both films to form thesubstrate layer 13 so that the printing layer is in the outer side. - When the
molding apparatus 25 is the heater or the light irradiation apparatus, in thepackaging film 11, foamable inks are contained as inks used for theprinting layer 19. Foaming agents are contained in foamable inks. As the foamable inks, the commercially available foamable inks can be used.
As the foaming agents, for example, other than the thermally decomposable chemical foaming agents such as azodicarbondiamide and azobisisobutylonitrile, the thermally expanding microcapsule forming agents with hydrocarbon with a low boiling point enclosed can also be used. As specific examples, Matsumoto microspheres F-30, F-50, F-80S, and F-85 (all are manufactured by Matsumoto Yushi-Seiyaku Co., Ltd.) can be exemplified. In addition, no problem occurs when no foaming agents are contained but the gas generated by oxidation and decomposition by laser light is contained. These can be used alone or in combinations. Also, for example, such foamable inks are used compounding 5 parts by weight of ammonium bicarbonate as the foaming agents in the ink constituted of 5 parts by weight of zeolite, 5 parts by weight of oxidative polymerization products, and 90 parts by weight of alkyd resin varnish. - As microcapsule foaming agents, for example, such microcapsules can be used in which the surface of the core material that evaporates or generates gas by heating is coated with a shell wall of a resin that hardly allows the air passage. To cite specific examples, microcapsules with a particle diameter of 5 to 40µm in which hydrocarbons being liquid with a low boiling point such as butane, pentane, and the like are used as core materials and thermosetting resins whose main ingredients are vinylidene chloride, acrylonitrile, vinylidene chloride-acrylonitrile copolymer, acrylic resin, aromatic vinyl compounds such as styrene and the like as shell walls can be exemplified.
- The foamable inks that contain microcapsules provide three dimensional unevenness on the surface of the
packaging film 11 by the heater or the light irradiation apparatus for the core material evaporates (or generates gas), expands, and breaks the shell wall, thereby leaving the broken traces of the foamable inks on thesubstrate layer 13 that contacts with theprinting layer 19. - A schematic sectional view is shown in
Fig. 5 as an example of the structure of thepackaging bag 10 when the three dimensional designs are formed by letting the printing layer contain the foamable inks. The structure of the layer of thebag 10 shown in theFig. 5 is, starting from the inner side, thesealant layer 12/the adhesive or apolyethylene layer 18/thesubstrate layer 13/thebarrier layer 17/the adhesive 18/theprinting layer 19/ thesubstrate layer 13. - When the
molding apparatus 25 is the mold, it is preferable that areinforcement sheet 14 is further laminated on the inner surface (sealant layer side) of thepackaging film 11 in addition to the basic structure of thepackaging film 11. Thereinforcement sheet 14 is a layer for reinforcing the portion of thepackaging film 11 subject to the three dimensional designs from the back surface in order to apply the three dimensional design decoration to thebag 10. For thereinforcement sheet 14 used in the present invention, materials with a thermoplastic property are selected as materials with a high retaining shape property under a room temperature and with light weight. In other words, at the time of embossing thepackaging film 11, the three dimensional designs can be easily imparted by heating while when cooled to the room temperature, the three dimensional designs have a relatively high retaining shape property. - As specific materials, thermoplastic resins such as polyethylene or polypropylene can be exemplified. Further, it is preferable that the thickness of the
reinforcement sheet 14 is 30 to 200µm. When the reinforcement sheet is too thin, the effect of providing the three dimensional decoration to the surface of the packaging bag is not satisfactory enough, while on the other hand, when the reinforcement sheet is too thick, since thereinforcement sheet 14 is partially formed on thepackaging film 11, it gets difficult to form thepackaging film 11 in tubular and the process passing capability is likely to be disrupted. - The
reinforcement sheet 14 can be laminated by bonding to thepackaging film 11 with general structures by adhesives and the like. However, bonding the reinforcement sheet over the whole surface of thepackaging film 11 is not applicable since it becomes difficult to vertically seal or horizontally seal thepackaging sheet film 11. In other words, it is necessary that thesealant layer 12 is provided to the outermost surface of the inner side of the portions subject to the vertical sealing or horizontal sealing of the bag. Therefore, in the present invention, when thereinforcement sheet 14 is provided, lamination is performed within the range that includes the range where the three dimensional designs are formed and that excludes the sealed range. In other words, it is preferable that the three dimensional designs for thebag 10 of the present invention is performed at predetermined portions within the range where thereinforcement sheet 14 is laminated in the inner side surface corresponding to the outer side surface of thebag 10. - The schematic sectional view as one example of the structure of the
packaging bag 10 when the three dimensional designs are formed providing thereinforcement sheet 14 on thepackaging film 11, is shown inFigs.6A and 6B . The layer structure of thebag 10 shown inFig.6A is, starting from the inner side, thereinforcement sheet 14/thesealant layer 12/the adhesive or thepolyethylene layer 18/thesubstrate layer 13/thebarrier layer 17/the adhesive 18/theprinting layer 19/thesubstrate layer 13. As another example of the structure, the example shown inFig.6B is constituted of, starting from the inner side, areinforcement sheet 14/asealant layer 12 /abarrier layer 17/an adhesive or apolyethylene layer 18 /aprinting layer 19/substrate layer 13. However, as mentioned above, in the both structures, the outermost layer in the inner side at positions where the vertical seal or horizontal seal are performed is asealant layer 12 and the reinforcement sheet is not laminated on this portion. - When the
molding apparatus 25 is the mold, it is preferable that the sheet for the threedimensional designs 15 is laminated on the substrate layer side of thepackaging film 11 and that the three dimensional design is formed by the mold to thepackaging film 11 in which the sheet for the threedimensional designs 15 is laminated. In addition, when the sheet for the threedimensional designs 15 is used, thepackaging film 11 with the sheet for the threedimensional designs 15 laminated may be prepared by preparing the laminate with thesubstrate layer 13 and the sheet for the threedimensional designs 15 laminated beforehand before forming thepackaging film 11 and by laminating thesealant layer 12 in the substrate layer side of the laminate. - As materials for the sheet for the three
dimensional designs 15, paper can be used. In particular, the paper with extendable property provided by fine unevenness is preferable. Such paper, by being used laminated on thepackaging film 11, can provide mechanical properties to thebag 10 such as strength, hardness, and the like and also, due to the excellent processing property of paper with extendable property, can easily form the three dimensional designs on the surface of the packaging bag for its uniquely shaped mold during the bag molding process. In addition, since the paper with extendable property provided by the fine unevenness has a high retaining shape property, the paper once formed with the three dimensional designs can keep the three dimensional designs for a long period of time. - As the paper used in the present invention with the extendable property provided by fine unevenness, Clupak paper utilizing shrinkage of a rubber belt and produced by making the rubber belt shrink, crepe paper produced by wrinkling wetted paper on a press roll or a drier roll using a doctor blade, paper with lateral and longitudinal stretches imparted at once by making it condense between a pair of rollers, and the like can be exemplified. Further details of such paper are disclosed in Patent Documents 2 (Re-disclosure in Japanese text
WO2004/028802 ) and 3 (Japanese Patent PublicationH11-509276 - As specific measures for obtaining the paper with the above mentioned properties, it is easy to obtain the trade name "wavywavy" manufactured and sold by Nippon Paper Group, Inc. Since this paper has strength of 4kN/m in 100g/m2 and has stretch of 15%, it can have usability alone as the sheet for the three
dimensional designs 15 and thesubstrate layer 13, however, it is preferable to use polyethylene, polypropylene, polyester film as materials for thesubstrate layer 13 and laminate them with the substrate later 13. Regarding the laminating methods of the sheet for threedimensional designs 15 and thesubstrate layer 13 for the paper substrate used in the present invention to which the extensible property is imparted, it can be performed by publicly known methods and for example, it is stated in Patent Document 3. It is preferable that the weight of the paper used in the present invention is 50 to 300g/m2. - A schematic sectional view showing one example of the structure of the
packaging bag 10 when the sheet for the three dimensional designs is provided is shown inFig. 7 . The structure of the layer of thebag 10 shown in theFig.7 is, starting from the inner side, thesealant layer 12/the adhesive 18/thebarrier layer 17/thesubstrate layer 13/sheet for threedimensional designs 15/theprinting layer 19. In addition, the embodiment shown inFig.7 shows the embodiment in which the sheet for threedimensional designs 15 and theprinting layer 19 are different layers, however, when the paper printed with the ink jet is used as the sheet for threedimensional design 15, the illustratedprinting layer 19 is integrated with the illustrated sheet for threedimensional design 15. - In addition, in the present invention, when the sheet for three
dimensional designs 15 is laminated on thepackaging film 11 and the material of the sheet for threedimensional designs 15 is paper, printing can easily be made to the paper for threedimensional designs 15 by such publicly known methods as ink jet methods without providing the printing layer separately. - A three
dimensional sheet 16 is a sheet imparted with the three dimensional designs beforehand by such methods as embossing by the molds and the like. Since the threedimensional sheet 16 is required to retain the three dimensional designs even when some shocks are applied to the surface of thebag 10, it is preferable that the materials used for the threedimensional sheet 16 are materials with a certain degree of strength. To be specific, it is preferable that the threedimensional sheet 16 is constituted of the same materials as those used for thesubstrate layer 13 such as polypropylene, polyester, and the like. The threedimensional sheet 16 can be made into abag 10 integrated with thepackaging film 11, by being bonded with thepackaging film 11 at the portion where no three dimensional designs is provided that is the surrounding portion of the three dimensional designs provided in the threedimensional sheet 16. In addition, the size of the threedimensional sheet 16 can appropriately be selected by the size of the bag and that of the three dimensional designs formed on the surface of the bag.
In thebag 10 of the present invention, the threedimensional sheet 16 provided with printing can also be used. In this case, instead of providing the printing layer on thepackaging film 11, the three dimensional sheet provided with the printing can be used or, the printing can be provided to the threedimensional sheet 16 as well as to provide theprinting layer 19 with thepackaging film 11. - As adhesives for bonding the three
dimensional sheet 16 to thepackaging film 11,hot melt adhesives 16A can preferably be used.Hot melt adhesives 16A are adhesives based on a thermoplastic polymer being solid at a room temperature with a property of showing fluidity in a liquid state when heated and restoring the original solid state when cooled. To be specific, reactive hot melt urethane series adhesives and copolymer polyester series hot melt adhesives can preferably be used. - A schematic sectional view as one example of the
bag 10 produced by the apparatus of the present invention when the threedimensional sheet 16 is provided to thepackaging film 11 using the hot melt adhesive 16A is shown inFig.8 . The structure of the layer of thebag 10 shown in theFig.8 is, starting from the inner side, thesealant layer 12/the adhesive or apolyethylene layer 18/thesubstrate layer 13/thebarrier layer 17/the adhesive 18/thesubstrate layer 13/the hot melt adhesive 16A/the threedimensional sheet 16. In addition, the schematic sectional view inFig.3 shows the embodiment of the threedimensional sheet 16 provided with printing without providing the printing layer to thepackaging film 11. - A producing method of bags provided with the three dimensional designs to the
packaging film 11 using the bag making-packagingmachine 20 by the heater is as follows. For information, the producing method of bags provided with three dimensional designs using the light irradiation apparatus can be conducted by the same method as when the heater is used. - First of all, the
packaging film 11 is provided to the bag making-packagingmachine 20 taking out thepackaging film 11 from the feed roll with thepackaging film 11 rolled. Thepackaging film 11 is formed in tubular by the pull-downbelt 24c in the process of conveying thepackaging film 11 from theshoulder portion 23a of the former 23 of the bag making-packagingmachine 20 to thetubular portion 23b, and then both film ends are overlapped in the film running direction while moving downward along the former surface, thereby performing vertical seal by thevertical seal mechanisms 21. As types of vertical seal, either an envelope seam sealing or a butt seam sealing is applicable. - When the above mentioned vertical seal is performed to the
tubular packaging film 11, heating by the heater for the three dimensional designs can be performed together. In order to heat thepackaging film 11 positioned on themolding surface 30 of the former 13 at the former 23, it is necessary to determine positioning the portion to be heated. In positioning, thesensor 27A senses the eye marks provided to thepackaging film 11 and the detection signal is output to thecontrolling mechanism 27C. By the input of the detection signal, the controllingmechanism 27C gives instructions to move theheater 15 by the moving mechanism27B so as tomake the heater that is themolding apparatus 25 contact with thepackaging film 11 on themolding surface 30 of the former 13. The moved heater heats thepackaging film 11 on themolding surface 30 from its outer surface. Foamable inks contained in the printing later 19 foam by heating and the three dimensional decoration is provided at predetermined positions of thesubstrate layer 13. After heating for a certain period of time, by the instructions of the controllingmechanism 27C, the heater is moved away from thepackaging film 11 and thepackaging film 11 is moved downward again by the pull-down belt 14c.
In addition, the signal detection of the eye marks for the positioning is not necessarily conducted on the surface of the former 13 to be heated, but rather, it is easier in process to conduct the signal detection of the eye marks when thepackaging film 11 is plane and before it is provided to the bag making-packagingmachine 20 as shown inFig.1A . - Next, in the
tubular packaging film 11, firstly, the lower end is sealed with appropriate intervals by thehorizontal seal mechanism 22 and at the same time of being formed to theuncompleted packaging bag 10 in which the upper end of thetubular packaging film 11 is opened, the product C passes through the inner side cavity of the tubular portion 13b of the former and is supplied to theuncompleted packaging bag 10. In the next step, when the upper end of theuncompleted packaging bag 10 is sealed by thehorizontal seal mechanism 22 as well as thepackaging bag 10 is cut off to the separate bags by the knife of thehorizontal seal mechanism 22, the three dimensional designs are provided on the surface and thepackaging bag 10 with the product C tightly packed and filled is completed.
In addition, in the producing method, although the process for performing the three dimensional designs at the time of vertically sealing thepackaging film 11 is shown, the process for performing the three dimensional designs can be provided before and after the vertical seal. - A producing method of bags provided with the three dimensional designs to the
packaging film 11 with the mold 26 using the bag-making andpackaging machine 20 is as follows. First, thepackaging film 11 is supplied to the bag-making andpackaging machine 20 rolling out thepackaging film 11 from the supply rolls with thepackaging film 11 rolled. Thepackaging film 11 is conveyed by the pull-downbelt 24c of the bag-making andpackaging machine 20 and moves toward theshoulder portion 23a of the former 23. In the embodiment of bonding thereinforcement sheet 14, in the process so far, thereinforcement sheets 14 are bonded to the predetermined portions of thepackaging film 11 at certain intervals. However, the reinforcement sheets are not bonded to the positions subject to the vertical seal and the horizontal seal in later process. Subsequently, thepackaging film 11 is shaped into tubular in the process of being conveyed from theshoulder portion 23a of the former of the bag-making andpackaging machine 20 to thetubular portion 23b, moved downward along the former surface, and the both ends of the film are overlapped and by thevertical seal mechanism 21, the vertical seal is performed. As types of vertically seal, either an envelope seam sealing or a butt seam sealing is applicable. - On the former rear side, the three dimensional designs are performed to the
packaging film 11 by the mold 26, while the vertical seal is conducted to the packaging film on the former front side. The flow chart of molding with the molds 26 (26A, 26B, and 26C) shown inFig.3 , applied to the apparatus shown inFigs.1A and 1B is as shown in the Table 1. - As above mentioned, preferable embodiment of the present invention is that the mold 26 provided to the former 23 is the male 26A and the opposing mold is the female 26B. In the female 26B, a heater (not illustrated) for heating the
packaging film 11 is built in, and theblower 26C for depressurizing inside of the mold when molding, and the movingmechanism 27B for forwarding and reversing the female toward the male 26A are provided. The register mark is detected in the process where thepackaging film 11 is supplied to the former 23, and the detection signal is output to thecontrolling mechanism 27C. Based on the information from thesensor 27A, the position of thepackaging film 11 at which the three dimensional designs are formed is specified. By the instructions of the controllingmechanism 27C, so that the three dimensional designs are formed at specified positions, the female 26B moves forward and at the same time, thevacuumblower 26C starts operation, thereby inside of the mold 26 is made vacuum and the molding is conducted. After the three dimensional designs are formed, with the instructions of the controllingmechanism 27C, the operation of theblower 26C stops and the female 26B moves backward and thepackaging film 11 is conveyed downward again by the pull-down belt 14c. - Next, the
packaging film 11, with its lower end sealed by thehorizontal seal mechanism 22 at appropriate intervals, is processed to be formed as an uncompleted bag with its upper end opened and at the same time, the product C is supplied to the uncompleted bag passing through the inner side cavity of thecylindrical portion 23b. Lastly, when the upper end of the uncompleted bag is sealed by thehorizontal seal mechanism 22 and is cut out into separate bags by the knife of thehorizontal mechanism 22, the three dimensional designs are provided on the surface and thebag 10 tightly packed and filled with the product C is completed. - In the embodiment of bonding the
reinforcement sheet 14, it is preferable that thepackaging film 11 is provided with a bonding mechanism for bonding thereinforcement sheet 14 to the side of the substrate layer before thepackaging film 11 reaches the tubular portion 13b of the former. - In
Fig. 9 , an outline is shown on one example of the bonding mechanism for thereinforcement sheet 14. The bonding mechanism of the reinforcement sheet is the mechanism for bonding the reinforcement sheet intermittently to thepackaging film 11. Before thepackaging film 11 is supplied to the vertical bag-making andpackaging machine 20, thereinforcement sheet 14 is laminated at predetermined portions that are the surfaces of the sealant layer of thepackaging film 11 and that exclude the portions where the vertical seal and the horizontal seal are formed, and the example in theFig. 9 shows that the surfaces laminated on thepackaging film 11 of the reinforcement sheet have a heat-sealable property. As shown in theFig.9 , thereinforcement sheet 14 is supplied on thepackaging film 11 as a continuous film, and the region laminated on thepackaging film 11 is divided by the perforation, and the divided portions are laminated to thepackaging film 11 by the hot press machine provided withheater plates 28 and 28' as shown in theFig.9 . Theheater plates 28 and 28' of the hot press machine may be the one that fixes the peripheral portions of the reinforcement sheet to thepackaging film 11 as shown in theFig.9 , or may be the one that fixes the whole surface. - The
reinforcement sheet 14 is bonded to its inner surface of thepackaging film 11 at predetermined portions at constant intervals by the bonding mechanism for the reinforcement sheet. However, thereinforcement sheet 14 is not bonded at positions where the vertical seal and the horizontal seal are performed. Subsequently, thepackaging film 11 is tubularly shaped in the process where it is conveyed from theshoulder portion 23a of the bag-making andpackaging machine 20 to thetubular portion 23b and moves downward along the former surface, and the both ends of the film are overlapped and by thevertical seal mechanism 21, the vertical seal is performed. As types of vertical seal, either an envelope seam sealing or a butt seam sealing is applicable. - Inaddition, although the process for the three dimensional designs at the time of the vertical seal of the
packaging film 11 are shown, the process for performing the three dimensional designs can be provided before and after the vertical seal. - A producing method of bags provided with the three dimensional designs to the
packaging film 11 by the pressing machined 29 using the bag-making andpackaging machine 20 is as follows.
It is common with the producing method using the mold 26 in that thepackaging film 11 moves downward along the former surface and is vertically sealed. - In parallel with the vertical seal of the
packaging film 11, at the rear side of the former 23, the threedimensional sheet 16 is bonded at predetermined portions by the bonding mechanism of the threedimensional sheet 16. This time, by making the bonding position of the rear side of the former 23 plane, the threedimensional sheet 16 can be bonded without failure. However, this time, the threedimensional sheet 16 is not bonded on the positions subject to the horizontal seal in later process.
Methods for bonding the threedimensional sheet 16 to thepackaging film 11 include the one which uses the threedimensional sheet 16 provided with the sealant layer or the hot melt adhesive 16A beforehand on the back surface of the three dimensional sheet, that is the surface bonded to thepackaging film 11, followed by heating this threedimensional sheet 16 to bond it or the one in which the melted hot melt adhesive is sprayed or coated to form the hot melt adhesive 16A at predetermined portions on the surface bonded to the surface of the packaging film, that is, the surface bonded to the threedimensional sheet 16 in the process right before bonding the threedimensional sheet 16 as shown inFig.4 , thereby bonding the threedimensional sheet 16 while the hot melt adhesive 16A is being melt.
The threedimensional sheet 16 before bonded to thepackaging film 11 can be prepared as, as shown inFig.4 , a continuous sheet in which the sheet portion to be bonded to the bag is divided by the perforation. The portions divided by the perforation break by applying force by the pressingmachine 29 thereby bonded to the surface of thepackaging film 11. - In the methods in which the sealant layer or hot melt adhesive is provided at the back surface of the three
dimensional sheet 16, while pressurizing the positions divided by the perforations of the threedimensional sheet 16 and heating, and while the threedimensional sheet 16 moves to the predetermined positions of thepackaging film 11, the threedimensional sheet 16 is bonded by the adhesive force of the sealant layer or the hot melt adhesive at the back surface of the threedimensional sheet 16.
On the other hand, in the methods in which the hot melt adhesive is formed by such methods as spraying, coating, or the like, first, a hot melt adhesive is laminated by theadhesive laminate apparatus 29A with the heating mechanism built in as shown inFig. 4 , on the predetermined portions in the front surface side of thepackaging film 11 made into tubular by the former 23. Next, while the hot melt adhesive 16A maintains the melted state, the threedimensional sheet 16 is bonded by the pressingmachine 29.
After the completion of the bonding process, the pressingmachine 29 retires. Such operation of thepressing machine 29 or that of theadhesive laminate apparatus 29A is controlled by cooperation of the movingmechanism 27B, thesensor 27A and of the controllingmechanism 27C. - An example of the appearance of the
bag 10 with the threedimensional designs 30 formed by the producing method is shown inFig. 10 . Contents of the threedimensional designs 30 include product images, designs that form corporate images providing the products, and catchphrases that become advertisements of the products, and as the threedimensional designs 30, it is effective to mark the depth of 1 to 20mm, and in particular, not less than 10mm. - Since the producing methods by the vertical packaging machines have been exemplified, the vertical bags with the three dimensional designs are produced, however, the packaging bags in the present invention are not limited to these vertical bags, and square bags with gussets or rectangular sealed bag can also be produced.
- Since the packaging bags with the three dimensional designs formed on the bag surfaces by the bag making-packaging apparatus of the present invention, by the provision of such packaging bags, the consumer appetite is stimulated and the sales of the merchandizes are improved by employing these packaging bags.
Also, when the three dimensional indications are provided to bags, the consumers come to see the indication attentively. Therefore, the apparatus of the present invention can be used extensively for producing bags and specifically for producing the packaging bags for foods.
