Description

  The present invention relates to a blister package and a method for producing a blister package. More specifically, the present invention forms a print space for printing a commercial instruction for a product by increasing it to about three times the back surface area of the mount, and prints a detailed product manual in the increased print space. A blister package that does not need to be attached separately to the blister package, and can be automatically manufactured by a simple heat welding process in a state where the product is stored in the blister, and The present invention relates to a method for producing a blister package.

Conventionally, products such as small products have been widely displayed and displayed in stores as blister packs.
Blister packs are preferred because the shape of the product protrudes three-dimensionally from the surface of the mount, which is preferred in order to urge buyers to purchase, but blister packs are made by blisters that protrude on the front side of the mount. Since the printing space on the front side of the mount cannot be used, there is a drawback that printing such as instruction manuals for the blister package is limited to the back side of the mount.
In the sale of many products, it is necessary to attach product manuals, etc. In the case of blister packs, the printed surface for the manuals is insufficient on the back of the mount alone, and there is a storage pocket for manuals etc. Separately provided blister packages or blister packs containing instruction manuals together with commodities are used. For example, a blister package is known in which a bag is attached to the back surface of the mount of the blister package and an instruction manual is placed inside the bag.
In this case, the product instruction manual attached to the small product and stored in the bag also becomes a small pamphlet, and the manual operation for storing the manual in the bag etc. is troublesome when manufacturing the blister package. There are such disadvantages. Also, it is troublesome for the purchaser to read the instruction manual from the bag.
Furthermore, such a blister package with an instruction manual requires manual work to store the instruction manual, and the blister package cannot be manufactured automatically.
In order to eliminate the disadvantages of this conventional blister package, the applicant has already increased the printing area on the back side of the mount approximately three times and attached the instruction manual by printing in this printing space. An unnecessary blister package is provided (Patent Document 1).
This blister package has a polyethylene resin sheet as a core material, and forms a mount in which the front side of the printed synthetic resin film is laminated on the front side of the core material, and the back side of the printed synthetic resin film is laminated on the back side. A thin flap made of a synthetic resin film printed on both sides is extended from the lower edge of the mount, and the back edge of the mount is peeled off in a semi-welded state. A blister package is formed by fixing to the side edges of the film. If this peelable double-sided printed flap is peeled off from the back side of the mount, printing on both the front and back sides of the flap and a total of three printing spaces can be secured.
At this time, it is possible to increase the printing space for printing for explaining the handling of the product by 2 to 3 times.
The blister package of the publicly known document is a blister package that does not require the attachment of an instruction manual, but in order to releasably fix a thin synthetic resin flap film printed on both sides to the back of the mount, Before fusing, it is necessary to apply a welding inhibition peeling varnish to the entire inner surface of the flap film. If both side edges are melted without this application, the side edges of the flap film are welded to the backing film, and the side edges can no longer be peeled off. Moreover, if the cutting of the side edge of the mount is mechanical cutting rather than fusing, the flap film cannot be attached to the back of the mount.
In addition, the flap film for double-sided printing is a solid image that prevents printing on both sides of the front and back sides from being confused so that the printing on both sides is blocked and the printed text and figures are clear. It is necessary to apply printing, for example, solid white printing or solid black printing. That is, the double-sided flap film needs to be printed three times: front printing, solid printing, and back printing, which is troublesome.
In the known blister package, the fixing of the flap film by fusing, the application of the welding-inhibiting peeling varnish, and the three-time printing of the flap film are essential.
Also, since the printing on the back side of the mount of the known blister package has a core material, the printing surface is rigid and the printing plane is stable, but the flap film does not have a core material, so when peeled off In addition, there is a functional defect that the printing surface moves with a flickering and it is difficult to read the instruction manual.
Furthermore, since the flap film is a thin film without a core and the back surface of the blister package is fixed only at the side edges, the central part of the flap film surface fixed to the mount floats. There are also disadvantages that make the appearance worse.
In general, a blister package can be manufactured by storing a product in a recess of a blister part and fixing it on the surface of the mount for automatic packaging of the product. That is, if a product storage process is incorporated into the blister packaging material manufacturing process, the manufacturing of the package by automatic packaging can be achieved. A belt conveyor type one-pitch movement of the blister part, a dropping process of the product into the concave part of the blister part, and a blister part containing the product placed at a predetermined position on the surface of the mount and a surface of the mount of the blister part by a robot hand It is possible to automatically carry out the fixing.
In this automation process, it is easy to install the blister part on the mount surface, but it is difficult to automate the process of fixing the blister part to the mount surface.
That is, when the blister part is bonded and fixed with an adhesive as in the known blister package, it is difficult to automatically apply the adhesive to the flange surface of the blister part.
In addition, if this is changed to a method in which the blister part is welded to the mount by thermal welding, the welding process itself can be easily automated. However, the mount is deformed by the welding heat, or the back printed surface of the mount is distorted. There are disadvantages.
JP 2006-131305 A

The present invention is a blister package that increases the number of prints on the back side of the mount of the blister package for explaining product handling, and does not require a separate product instruction manual, and the automatic packaging manufacturing process is simple. The purpose of the present invention is to provide a blister packaging body that has a good packaging format and is convenient for display sales.
Specifically, it is possible to omit the process of applying the adhesion-inhibiting peeling varnish on the inner surface of the blister package with the printing flap film, which is the prior art, avoiding the three-time printing of the flap film, and the flexibility of the thin film of the flap film. The present invention provides a blister package that eliminates the drawbacks of floating from the mount of the printing surface and a method for producing a blister package that is easy to automatically package.

As a result of intensive research to solve the above-mentioned problems, the present inventor conducted a dry laminating process for printing resin films on both sides of a polyethylene resin sheet containing 65 to 85% by weight of inorganic powder composed of 80% by weight or more of calcium carbonate. A vertically long rectangular double-sided printed laminated polyethylene resin sheet formed by laminating is divided into a front side polyethylene resin sheet and a back side polyethylene resin sheet by a folding line in the width direction, and the front and back are folded twice to be polymerized, The inner surfaces of each other are preliminarily bonded to each other by a heat-sensitive adhesive layer applied to each surface to form a rectangular mount in which the front-side laminated polyethylene resin sheet and the back-side laminated polyethylene resin sheet are integrally laminated. When the back side polyethylene resin sheet on the back side is peeled off, the back side of the mount of the blister package Utilizing the phenomenon that the three printed surfaces appear, it secures the printing space necessary for the handling explanation of the product, and further avoids the difficulty of three-time printing, which was a disadvantage of the prior art. A blister package that does not lift up and that can eliminate the step of applying a printing flap film adhesion-inhibiting release varnish in the manufacturing process has been completed.

The blister package of the present invention comprises a printed thermoplastic synthetic resin film having a heat-sensitive adhesive layer on one side of a polyethylene resin sheet containing 65 to 85% by weight of inorganic powder consisting of 80% by weight or more of calcium carbonate. A laminated polyethylene resin sheet having a three-sheet laminated structure in which the printed surface of the printed thermoplastic synthetic resin film is dry-laminated toward the polyethylene resin sheet side is heat-sensitive. The laminated surface of the printed thermoplastic synthetic resin film having an adhesive layer is bent and polymerized by folding it in half, and this is thermocompression bonded to the printed inner surface of the laminated polyethylene resin sheet on the printed thermoplastic synthetic resin film surface. The heat-sensitive adhesive layer that has been applied is fixed in a peelable state by thermal bonding.
On the back side of the blister package of the present invention, a rectangular first printing surface with the dimensions of the mount can be seen. When the laminated polyethylene resin sheet piece having the first printed surface (hereinafter referred to as a peeled laminated polyethylene resin sheet piece) is peeled off with a finger, the first layer of the laminated polyethylene resin sheet hidden underneath is replaced with the first printed surface. 2 printed surface appears on the back side of the mount. Together with this second printed surface, a third printed surface appears on the back surface of the peeled laminated polyethylene resin sheet piece. When the peeled laminated polyethylene resin sheet piece that has been bonded to the back surface side with the heat-sensitive adhesive layer is peeled off with a finger, a total of three printed surfaces can be exposed.
The printed film on these three printed surfaces is printed on the inner surface of a resin film that is firmly adhered and laminated to the polyethylene resin sheet surface by dry laminating, and the release laminated polyethylene resin sheet piece faces the laminated polyethylene. Since the heat-sensitive adhesive layer is adhered to the entire surface of the resin sheet surface, the printed layer does not float from the surface of the polyethylene resin sheet, and is clear against the background color of the polyethylene resin sheet of the peeled laminated polyethylene resin sheet piece. A printed pattern is formed.
In the blister package of the present invention, the mount is a polymer of a laminated polyethylene resin sheet, and is a laminate of 6 layers in total. Since the 6 layers are adhered to the entire surface by a dry laminating adhesive or pressure sensitive adhesive, the respective layers are not separated even if the side edges of the blister package are mechanically cut in the manufacturing process. There is no separation.
Moreover, when the side edge of the blister package is melted with a hot blade in the manufacturing process of the blister package, the peeled laminated polyethylene resin sheet piece is semi-welded, so that the laminated polyethylene resin sheet piece is peeled off from the end by the friction that occurs during handling. This can be completely prevented. And since the heat-sensitive adhesive layer is applied to the entire surface, the heat-sensitive adhesive layer applied in a double manner between the laminate with the peeled laminated polyethylene resin sheet piece during the step of fusing the side edge of the backing sheet prevents welding. Since the side edge of the blister package is in a semi-welded state because it exerts its action, when peeling the peeled laminated polyethylene resin sheet piece with a finger, it can be easily peeled off with a little strong force.
In the present invention, since a resin film is laminated on a polyethylene resin sheet, the flange of a blister containing a product can be welded to the front film by thermal welding, particularly spot welding, so that an automatic blister package The packaging manufacturing process is easy.
Further, in the mount structure in which two laminated polyethylene resin sheets are polymerized, it is easy to warp when heat is applied to one side. However, in the present invention, 65 to 65 inorganic powders mainly composed of calcium carbonate are added to the polyethylene resin sheet of the laminated polyethylene resin sheet. Since 85% by weight is contained, there is an advantage that the board does not warp in the thermocompression bonding process of the dry lamination process of the board. In the blister package, the warping of the mount significantly reduces the appearance of the blister package and reduces the commercial value. Further, there is an advantage that it is possible to prevent the warp of the mount due to heat when the blister part is welded to the surface side of the blister package.

FIG. 1 is a front view of one embodiment of the blister package of the present invention, and FIG. 2 is a central sectional view of FIG.
The base plate 1 of the blister package of FIG. 1 has an elongated rectangular laminated polyethylene resin sheet 6 (FIG. 3) as shown in the sectional view of FIG. It is divided into side laminated polyethylene resin sheet pieces 6b (laminated polyethylene resin sheet pieces), folded with the surface of the printed thermoplastic synthetic resin film 11 having the heat-sensitive adhesive layer 10 facing the inner surface, and thermocompression bonded. Two layers of the heat-sensitive adhesive layer 11 provided on each surface of the two printed thermoplastic synthetic resin films 11 are welded to form a front-side laminated polyethylene resin sheet piece and a back-side laminated polyethylene resin sheet piece (laminated polyethylene resin sheet piece). A portion of the rectangular mount 1 is formed by temporary contact and fixing. The laminated polyethylene resin sheet used as the material has the same width as the predetermined width of the rectangular mount, and the vertical length is approximately twice the predetermined length of the rectangular mount. The mount 1 can be obtained.

The surface of the flange 4 of the blister part 3 is welded to the thermoplastic resin film on the surface side of the mount 1 by the spot-shaped thermocompression bonding parts 5 by spot welding. A suspension hole 2 is formed in the upper part of the mount 1, and a product 16 is stored in the blister part 3.
The method of fixing the blister portion of the blister package of the present invention to the thermoplastic resin film on the surface side is not limited to the welding fixing means, and can be stably fixed to the thermoplastic resin film on the surface side. It can be used without particular limitation. For example, the flange surface of a blister part can be adhere | attached on the thermoplastic resin film of the surface side with an adhesive agent. In addition, the surface side laminated polyethylene resin sheet piece has a hole of the same size as the blister part, the blister part protrudes only from the back of the surface side laminated polyethylene resin sheet piece, and the flange side is the surface side laminated polyethylene resin. The sheet piece and the back-side laminated polyethylene resin sheet piece can be sandwiched and fixed.
FIG. 3 is a cross-sectional view showing a laminated structure of one aspect of the laminated polyethylene resin sheet 6 constituting the mount 1 of the blister package.
The laminated polyethylene resin sheet 6 used in the present invention has a polyethylene resin sheet 7 containing 65 to 85% by weight of inorganic powder composed of 80% by weight or more of calcium carbonate as a core material sheet, and a printed thermoplastic synthetic resin film 8 on the surface side. The printed surface is brought into close contact with the polyethylene resin sheet 7 side, and is laminated and fixed to the dry laminate adhesive layer 9 by a dry laminating method. On the other back side, the printed thermoplastic synthetic resin film 11 is also printed with the polyethylene resin. A heat-sensitive adhesive is applied to the non-printing surface opposite to the printing surface of the printed thermoplastic synthetic resin film 11 which is adhered to the sheet 7 side and laminated and fixed to the dry laminating adhesive layer 9 by a dry laminating method. The entire surface of the laminated polyethylene resin sheet 6 is covered with a thin heat-sensitive adhesive layer 10 To have.
As long as the adhesive used in the dry laminating process of the present invention is an adhesive that can be used in a known dry laminating process, any of pressure-sensitive adhesives, heat-sensitive adhesives, and curable adhesives is used without limitation. be able to.

The heat-sensitive adhesive layer provided on the surface of the printing thermoplastic synthetic resin film of the present invention can be formed by applying a melted heat-sensitive adhesive on the surface having no printing surface. Moreover, it can dry after apply | coating a thermoplastic resin solution, and can form an application layer.
As the heat-sensitive adhesive, a thermoplastic resin blended with a pressure-sensitive adhesive or wax, if desired, can be used. For example, what is called a hot melt adhesive can be used. As the thermoplastic resin, thermoplastic resins such as ethylene vinyl acetate, polyolefin, atactic polypropylene, polyamide, and polyester, rosin, petroleum resin, and the like can be used.
The heat-sensitive adhesive layer used in the present invention is desirable in that the low melting point resin is easy to be thermocompression bonded.
The front-side laminated polyethylene resin sheet piece 6a and the back-side laminated polyethylene resin sheet piece 6b of the present invention are fixed by welding with a heat-sensitive adhesive layer, but the upper end of the back-side laminated polyethylene resin sheet piece 6b is downward with a nail. When peeled off, the entire surface of the back-side laminated polyethylene resin sheet piece 6b can be easily peeled off, and the second printed surface and the third printed surface can be seen. Since the adhesive force obtained by attaching the printed thermoplastic synthetic resin film by dry laminating is much larger than the peeling force applied on the peeling line when the back side laminated polyethylene resin sheet piece 6b is peeled off, the back side laminated polyethylene During the operation of peeling the resin sheet piece 6b, the dry-laminated printing thermoplastic synthetic resin film does not float from the surface of the polyethylene resin sheet. And after peeling once, unless it thermocompression-bonds, the back surface side laminated polyethylene resin sheet piece 6b cannot be stuck as it was.
Previously, printed paper with a glossy ultra-thin polypropylene film or polyester film laminated on the surface of the printed paper to protect the printed pattern from scratches and improve the appearance of the printed surface. Was widely used. Instead of this printed paper, traditionally, printing is performed on the back side of the film to be laminated, and this laminated film is bonded to a predetermined position on the paper to make it appear as if it was printed on the paper. The method has become widely used.
The present invention employs a printing means that prints the printed pattern on the back surface of the film without applying the printed pattern on the surface of the core sheet, and laminates the printed pattern of the printed film in a predetermined position on the core sheet. .
The printing thermoplastic synthetic resin film of the present invention can usually be used up to a thickness of about 10 to 65 μm. However, in order to make the printed pattern look good and clear when laminated, the thickness is The thinner it is, the better. However, since the strength is lowered when the thickness is reduced, a polypropylene film and a polyester film having strength are particularly desirable.
These films are suitable from the viewpoints of gloss and scratch resistance imparted to a printed pattern, even if they are thin, have strength to withstand dry lamination and printing, have good transparency.
The resin of the printed thermoplastic synthetic resin film used in the present invention is desirable in terms of strength even when the polypropylene resin or polyester resin is thin, and in terms of surface gloss to make the printed pattern appear. Further, when fixing the blister part by welding It is desirable that both the blister part and the printed thermoplastic synthetic resin film are made of the same kind of resin, that is, made of polypropylene resin or polyester resin, in that the manufacturing process becomes easy.

The inorganic powder-containing polyethylene resin sheet used as the core of the two-layer laminated polyethylene resin sheet of the mount used in the present invention can be used without particular limitation as long as it has a smooth surface that can be laminated. A sheet having a certain degree of rigidity, such as about 60 to 300 μm, is desirable as the mount.
As the polyethylene resin used for the inorganic powder-containing polyethylene resin sheet of the present invention, high-density polyethylene, low-density polyethylene, medium-density polyethylene, and a polyethylene copolymer containing a small amount of other monomers can also be used.
Further, a polyethylene resin sheet obtained by blending these polyethylene resins, for example, a blended polyethylene resin sheet containing 40 to 60% by weight of high density polyethylene, 60% to 40% by weight of low density or medium density polyethylene, is warped by the thermocompression bonding process. It can be suitably used with few points.
Even if a large amount of inorganic powder is blended in the polyethylene resin sheet of the present invention, the folds are not broken when the laminated polyethylene resin sheet is folded into two sheets when the mount is formed. In particular, the polyethylene-brene resin obtained by blending low-density or medium-density polyethylene with high-density polyethylene can smoothly perform the folding process of the laminated polyethylene resin sheet in the production of the blister package of the present invention.
The inorganic powder used in the polyethylene resin sheet containing the inorganic powder of the present invention is an inorganic powder composed of 80% by weight or more of calcium carbonate. When the calcium carbonate content is less than 80% by weight, the effect of preventing the warp of the laminated board in the heat treatment step is lowered.
As inorganic powders other than calcium carbonate, titanium dioxide, silicon dioxide, bentonite, clay, diatomaceous earth, calcium sulfate, kaolin, mica, and zinc oxide can be used. Is preferred.
The polyethylene resin sheet of the present invention is blended with calcium carbonate, the sheet surface is white with high brightness, and the back surface printed pattern of the laminate film is in close contact with the polyethylene resin sheet surface, as if printing directly on the sheet surface Although it looks like it is being applied, it can be mixed with a light-colored pigment or dye to give a background color that makes the printed pattern of the printed film shine with high brightness.
As the polyethylene resin sheet of the present invention, a synthetic paper sheet having a low content of a general inorganic powder not corresponding to a polyethylene resin sheet containing 65 to 85% by weight of inorganic powder consisting of 80% by weight or more of calcium carbonate, and a solvent-fired inorganic powder. Although almost no synthetic paper can be used as the core resin sheet of the present invention, the mount becomes warped during the thermocompression bonding process, and the appearance when it is displayed as a blister package is deteriorated.
The printed thermoplastic synthetic resin film to be dry laminated on the back side of the laminated polyethylene resin sheet used in the present invention is a film obtained by printing on a printed thermoplastic synthetic resin film having a thickness of 10 to 100 μm, preferably 30 to 70 μm. It can be laminated on a polyethylene resin sheet by dry lamination.
As the polypropylene resin in the case of using the printed polypropylene resin film of the present invention, commercially available homopolypropylene, randomane polypropylene, and block polypropylene resin films can be used. This is desirable.
The printed thermoplastic synthetic resin film to be dry laminated on the surface side of the laminated polyethylene resin sheet used in the present invention is a film obtained by printing on a resin film having a thickness of 10 to 100 μm, preferably 30 to 70 μm. It can be laminated by dry lamination.
A flange of a blister package is welded and fixed to a printing thermoplastic synthetic resin film 8 which is dry laminated on the surface side of the laminated polyethylene resin sheet 6 of the present invention.
The printing thermoplastic synthetic resin film 8 to be laminated on the front side of the laminated polyethylene resin sheet of the present invention for welding and fixing is a thermoplastic resin having the same quality as the flange of the blister part. This is particularly desirable because the strength of the welded portion increases. Therefore, when a polypropylene resin film is selected as the printing thermoplastic synthetic resin film 8 to be laminated on the front side of the laminated polyethylene resin sheet, it is desirable to select a polypropylene resin as the material of the blister portion. Similarly, when a polyester resin film is selected as the printing thermoplastic synthetic resin film 8 to be laminated on the front side of the laminated polyethylene resin sheet, it is desirable to select a polyester resin as the material of the blister part.
The blister part used for this invention can use the integral thermoplastic resin molded product which consists of a goods storage part and the flange part of the periphery. Since the attachment to the laminated polyethylene resin sheet is performed by thermocompression bonding from the outer surface, the thickness of the flange surface of the blister part is preferably less than 1 mm.
The welding and fixing of the blister part is desirable in that the heating part of spot welding from the outside of the flange surface is concentrated and limited so that welding can be performed quickly and easily and the distortion of the welded part is small.

The spot welding of the present invention is particularly suitable in the continuous production process of the blister package of the present invention in that spot welding can be freely performed.
In the present invention, basically, as shown in FIG. 2, the substantially central portion of the laminated polyethylene resin sheet is divided into a front-side laminated polyethylene resin sheet piece 6a and a back-side laminated polyethylene resin sheet piece 6b and bent, A portion of the rectangular mount 1 is formed by pressure bonding. In this case, when peeling back side laminated polyethylene resin sheet piece 6b, it will peel from the upper end. At this time, the level | step difference 12 can be formed in the upper end of a mount by slightly shifting the position which bends the back side laminated polyethylene resin sheet piece 6b from the center. When there is this level | step difference 12, operation which peels the back surface side laminated polyethylene resin sheet piece 6b becomes very easy.
In the present invention, as shown in FIG. 4, the laminated polyethylene resin sheet having a length approximately twice as long as that of the mount is on a horizontal direction line shifted from the center in the lengthwise direction, and has an interval equal to the length of the mount. Two places are folded by the parallel crease lines 13 and 14, and the laminated polyethylene resin sheet is polymerized so that both ends of the laminated polyethylene resin sheet substantially coincide at the position of the joint 15 on the back side of the mount, and the mount is used. Can do. In this case, the interval between the two parallel crease lines 13 and 14 exactly matches the size of the mount, but the back side laminated polyethylene resin sheet piece 6b, which is the total dimension of the upper and lower margins of the parallel crease lines 13 and 14, , It can be made to not exactly match the dimensions of the mount. In this case, both ends of the laminated polyethylene resin sheet are displaced on the back side of the mount, and a slight overlapping portion is generated, or conversely, the gap is not achieved and a slight gap is generated. This overlapping portion or gap serves as a grip piece when the back side laminated polyethylene resin sheet piece 6b is peeled off, and may be a convenient overlapping or gap in some cases.
In the present invention, by using a polyethylene resin sheet containing 65 to 85% by weight of calcium carbonate, when the flange surface of the blister part is welded to the surface-side laminated polyethylene resin sheet piece 6a of the mount, Thermal deformation of the polyethylene resin sheet piece 6a can be prevented.
In particular, when the blister part is thermally welded to the mount of the present invention, there is a high possibility that the mount is warped. When a polyethylene resin sheet containing 65 to 85% by weight of calcium carbonate is used, it is possible to eliminate the warp of the mount that occurs during the welding process of the blister part, and to achieve a good display.

In addition, the packaging material of the blister packaging body of the present invention is inevitably discarded after use of the product, but when it is discarded and incinerated, the combination of calcium carbonate prevents the rise of combustion heat and damages the incinerator. There is an advantage that the generation of carbon dioxide gas can be prevented and the generation of carbon dioxide gas is reduced by about 25%.
When the blister package of the present invention is heat-fixed and fixed to the blister part, it can be manufactured by the following procedure using a combination of steps used in the continuous manufacturing method of plastic packaging bags.
(A) A printing thermoplastic synthetic resin film having a width that is twice the size of the mount of the target blister package, dry-laminated with a printed thermoplastic synthetic resin film on one side, and a heat-sensitive adhesive layer on the other side The long laminated polyethylene resin sheet that has been dry-laminated is sent to the bending process.
(B) In the folding step, the center line of the long laminated polyethylene resin sheet is continuously folded with the printed thermoplastic synthetic resin film side having the heat-sensitive adhesive layer inside, and half-fold polymerization is performed, and the width of the length of the mount A long two-layer laminated polyethylene resin sheet corresponding to the above is formed.
(C) The two-layered laminated polyethylene resin sheet is sent to the thermocompression bonding step, and the two-layered laminated polyethylene resin sheet is continuously thermocompression bonded by the thermocompression roller.
(D) A long two-layer laminated polyethylene resin sheet subjected to thermocompression bonding is switched to one-pitch transfer and sent to the heat welding process.
(E) Simultaneously synchronize the long laminated polyethylene resin sheet with the one-pitch transfer of the long laminated polyethylene resin sheet and send out the blister part containing the product at the same time as the one-pitch transfer of the long laminated polyethylene resin sheet. After contacting a predetermined position on the surface side of the long laminated polyethylene resin sheet in the welding process, the flange surface of the blister part is heated to the surface side thermoplastic synthetic resin film of the long laminated polyethylene resin sheet by spot welding. Weld and fix.

In order to store the product in the blister part, the product is put into the blister part being transferred by the conveyor belt by the robot hand, and the flange surface of the blister part in which the product is stored is made of a long two-layer laminated polyethylene resin sheet. It is desirable that the surface side thermoplastic resin film is in contact with a predetermined place (from above or below), hits the flange surface of the blister (presses from above or below), presses the welding spot, and then cools and welds. It is an automatic packaging process.
(F) A long laminated polyethylene resin sheet with a blister part is cut for each dimension of the mount. This cutting cuts the side edge of the blister package. Even if fusing is used for this cutting, since the heat-sensitive adhesive layer acts as a welding inhibitor, the side edges of the front-side laminated polyethylene resin sheet piece 6a and the back-side laminated polyethylene resin sheet piece 6b may be strongly welded. It can be peeled off with the finger.
When complete sealing is required until the back side laminated polyethylene resin sheet piece 6b is opened, it is desirable to cut the long laminated polyethylene resin sheet with a blister part by fusing.

  Since the blister package of the present invention can directly print the product instruction manual on the packaging material of the blister package to form three printed surfaces on the back side of the blister package, the product instruction manual is attached separately.
