Description

  The present invention relates to a polymer film-bonded paper, and more particularly to a polymer film-bonded paper suitable for a package for packaging an object such as a cigarette.

  Package paper used for packages for packaging objects such as cigarettes is aluminum bonded paper, polyethylene terephthalate (PET) bonded paper, or aluminum vapor-deposited paper for the purpose of giving cosmetics such as brightness and gloss. Is used. The aluminum bonding paper is formed by bonding aluminum to a base paper, and the PET bonding paper is formed by bonding a PET film to the base paper. Aluminum vapor-deposited paper means that aluminum is vapor-deposited on a film such as a PET film, polypropylene (PP) film, polyvinyl chloride (PVC) film, or polyvinyl alcohol film, and the paper is bonded to the film via an adhesive. It is a thing.

  For example, Patent Document 1 discloses a polyvinyl alcohol laminated paper in which a base paper is bonded to a polyvinyl alcohol film via an adhesive, and an aluminum vapor deposition layer of a transfer foil obtained by vacuum vapor deposition of aluminum is transferred to the polyvinyl alcohol film.

Japanese Patent Publication “JP 2012-101418 A (published May 31, 2012)”

  However, conventionally used package paper has the following problems when various ruled lines for assembling into a package are formed in a blank. First, in the aluminum bonding paper, there is a problem that the aluminum layer does not extend following the ruled line processing, and the formed ruled line part is easily broken. If the ruled line portion formed in the blank breaks, the blank becomes a defective product, and the production efficiency of the blank decreases.

  Moreover, in PET bonding paper, since PET film is hard, package paper will warp. If the package paper is warped up, it will not be adsorbed well when it is sucked and transported by physical transport such as electrostatic chuck, belt transport, or air chuck transport. Efficiency will decrease. Furthermore, in the PET laminated paper on which a hard PET film is bonded, the vicinity of the cut portion is lost during cutting such as printing punching, and cutting scraps resulting from cutting of the PET film are generated. Such cutting waste may be mixed in the package.

  Further, in the aluminum vapor-deposited paper, it is difficult for the package paper to warp, but there is a problem that the surface of the package paper is likely to be scratched or stained. If the surface of the package paper is scratched or dirty, the cosmetic quality of the package is impaired.

  Then, this invention is made | formed in view of said subject, The objective is to provide the bonding paper by which curvature rise is suppressed and high cosmetics can be maintained.

  In order to solve the above-described problems, a polymer film-laminated paper according to one embodiment of the present invention is a polymer that is subjected to cutting into a predetermined shape and forming a ruled line that becomes a fold line in order to form a package. It is a film bonding paper, and is characterized by comprising a polymer film having a tensile elastic modulus in the range of 1000 to 2500 MPa.

  According to said structure, in the polymer film bonding paper which concerns on 1 aspect of this invention, when forming various ruled lines with respect to a polymer film bonding paper, a polymer film bonding paper is made into a flat state. Can keep. This is because the polymer film used for the polymer film-laminated paper has high flexibility, and the polymer film can be sufficiently stretched during ruled line formation. In addition, since the polymer film has high flexibility and appropriate elasticity, the polymer film is neatly cut at the time of cutting such as printing punching, and cutting scraps are hardly generated. Furthermore, since a polymer film is used for the polymer film-laminated paper, the surface is hardly scratched or soiled.

  Therefore, the polymer film-bonded paper according to one embodiment of the present invention can prevent warping during ruled line formation and can maintain high cosmetic properties. Note that the polymer film used in the polymer film-bonded paper according to one embodiment of the present invention has low warpage due to changes in temperature and humidity. Therefore, it becomes easy to manage the temperature and humidity of the warehouse where the polymer film-bonded paper is stored.

  In the polymer film bonding paper which concerns on 1 aspect of this invention, when forming various ruled lines with respect to a polymer film bonding paper, a polymer film bonding paper can be maintained in a flat state. This is because the polymer film used for the polymer film-laminated paper has high flexibility, and the polymer film can be sufficiently stretched during ruled line formation. Moreover, since the polymer film bonding paper uses a polymer film having high flexibility, the surface is hardly scratched or soiled. Therefore, the polymer film-bonded paper according to one embodiment of the present invention can prevent warping during ruled line formation and can maintain high cosmetic properties.

It is a figure which shows the cross section of the polymer film bonding paper which concerns on the 1st Embodiment of this invention. It is a perspective view which shows the state which punched the package blank from the polymer film bonding paper which concerns on the 1st Embodiment of this invention, and formed the various ruled lines for assembling in a package in the said blank.

  Embodiments of the present invention will be described in detail with reference to the drawings. In the following description, members having the same function and action are denoted by the same reference numerals and description thereof is omitted.

[First Embodiment]
(Composition of polymer film bonding paper)
The polymer film bonding paper which concerns on this embodiment is a package paper used for the package which accommodates to-be-received bodies, such as a cigarette. The polymer film bonding paper 1 which concerns on this embodiment is demonstrated with reference to FIG. 1 and FIG. FIG. 1 is a view showing a cross section of the polymer film-bonded paper 1. FIG. 2 is a perspective view showing a state in which a blank of a package is punched from the polymer film bonding paper 1 and various ruled lines for assembling the package are formed on the blank.

  As shown in FIG. 1, the polymer film bonding paper 1 which concerns on this embodiment is formed by laminating | stacking the polymer film 2, the aluminum vapor deposition layer 3, the contact bonding layer 4, and the base paper 5 in an order from the top. Specifically, in the polymer film bonding paper 1, aluminum is vapor-deposited on one surface of the polymer film 2 to form the aluminum vapor-deposited layer 3, and the surface on the side where the aluminum vapor-deposited layer 3 is formed is formed. As a bonding surface, it is bonded to the base paper 5 through the bonding layer 4.

  As shown in FIG. 2, a package blank is punched out from the polymer film laminated paper 1 formed in this manner, and various ruled lines 6 for assembling the package are formed in the blank. The ruled line 6 is a groove-shaped fold line when the blank is bent. In FIG. 2, in order to make the drawing easier to see, only some of the ruled lines are given member numbers. The ruled line 6 is formed into a groove shape by pressurizing the blank with a pressurizing jig or the like, and is deep enough to deform the surface of the blank opposite to the surface to be pressed into a convex shape. Is formed. The blank may be provided with a perforated lead ruled line at a portion that becomes a glue portion when assembled into a package. By applying such lead ruled lines, the adhesiveness of the glued portion can be enhanced.

(Characteristics of polymer film)
In the polymer film bonding paper 1 according to this embodiment, a polymer having a tensile elastic modulus of 1000 to 2500 MPa extends so that the polymer film 2 bonded to the base paper extends following the ruled line processing when the ruled line is inserted. The film 2 is bonded to the base paper 5. Thereby, it can prevent that the bonding paper which gave the ruled line does not curve. The tensile elastic modulus is represented by the ratio of the tensile stress per unit cross-sectional area to the elongation generated in the stress direction. The larger the numerical value, the smaller the stress strain. The tensile elastic modulus can be measured according to, for example, ISO527-1 and ISO527-2.

Furthermore, in the polymer film bonding paper 1 which concerns on this embodiment, the Charpy impact strength which shows the toughness of a substance is 50-150 kJ / m < ² > so that the curvature of a bonding paper may be reduced greatly and high mechanical suitability may be shown. The polymer film 2 having a relatively high value is bonded to the base paper 5. The Charpy impact strength is a notched Charpy impact strength, which is a value obtained by dividing the impact energy absorbed when a notched specimen is broken by the initial cross-sectional area of the specimen. The Charpy impact strength can be measured, for example, according to ISO179-1. By having the Charpy impact strength within this numerical range, the nylon film extends following the ruled line processing when the ruled line is inserted, so that warping of the laminated paper subjected to the ruled line processing is greatly suppressed. Moreover, generation | occurrence | production of the cutting waste in a punching process can be suppressed.

A nylon film (especially a film made of 6 nylon) is mentioned as a material that satisfies this condition. If it is a nylon film, the curvature of a bonding paper will be reduced greatly and it has high mechanical suitability. The PP film has a tensile elastic modulus in the range of 1000 to 2500 MPa, but the Charpy impact strength is not in the range of 50 to 150 kJ / m ² . Therefore, in the PP film, the warp at the time of ruled line formation is reduced as compared with the PE film and the PET film. However, even with a slight warp, a high-speed machine such as a cigarette wrapping machine needs to make a great effort to adjust the wrapping machine, and PP film does not sufficiently suppress the warping.

Thus, in the polymer film bonding paper 1 which concerns on this embodiment, the polymer film 2 whose tensile elasticity modulus is 1000-2500 Mpa is used, The Charpy impact strength is 50-150 kJ / m < ² >. It is preferable that it is 80-120 kJ / m < ² >. In addition, in the polymeric film bonding paper 1, it is preferable that the tensile elasticity modulus of the polymeric film 2 is the range of 1000-2000 MPa, and it is more preferable that it is the range of 1250-1750 MPa.

(Rule line processing of polymer film bonding paper 1)
The perspective view which shows the state which stamped the blank of the package from the polyethylene terephthalate (PET) film bonding paper in FIG. 3, and formed the various ruled lines for assembling into a package in the said blank is shown. In aluminum bonding paper, when forming various ruled lines with respect to the blank, the aluminum layer does not extend following the ruled line processing, and the ruled line part formed in the blank is easily broken. Moreover, in PET film bonding paper, when forming various ruled lines with respect to a blank, as shown in FIG. 3, the bonding paper will warp. In the case of this figure, since many ruled lines are formed in the longitudinal direction of the blank (left and right direction in the figure), the edge portion substantially parallel to the ruled lines is greatly warped. This is because the PET film is hard and the PET film cannot be sufficiently stretched during ruled line formation. Moreover, in PET film bonding paper, the cutting waste of cutting will generate | occur | produce at the time of cutting, such as printing punching. This is also because the PET film is hard and the vicinity of the cut portion is missing. Further, in the case of aluminum vapor-deposited paper, the bonding paper does not warp when forming various ruled lines on the blank, but the surface of the bonding paper is likely to be scratched or soiled.

  In addition, in the case of a laminated paper using a very soft polymer film such as a polyethylene (PE) film, the adhesive paper does not have elasticity, and even in this case, there is a possibility that cutting may occur during cutting. . In addition, when a very soft polymer film is used, when transporting the bonding paper in the packaging machine, the bonding paper is greatly bent and the residence time becomes longer, which may cause a decrease in production efficiency. Is done.

  However, in the polymer film bonding paper 1 which concerns on this embodiment, when forming various ruled lines with respect to a blank, as shown in FIG. 2, the bonding paper can be maintained in a flat state. This is because the polymer film 2 used for the polymer film bonding paper 1 has high flexibility, and the polymer film 2 is sufficiently stretched when forming ruled lines. In addition, since the polymer film 2 has high flexibility and appropriate elasticity, the polymer film 2 is neatly cut at the time of cutting such as printing punching, and cutting cut waste is generated. hard. Furthermore, in the polymer film bonding paper 1, since the polymer film 2 is bonded to the outermost surface, the surface is hardly scratched or soiled. Therefore, the polymer film-laminated paper 1 can prevent warping during ruled line formation and cutting waste during cutting, and can maintain high cosmetic properties.

  In addition, even if a PET film bonding paper is accompanied with the change of temperature and humidity, curvature will generate | occur | produce. Therefore, when storing PET film bonding paper in a warehouse, it is necessary to strictly manage the temperature and humidity of the warehouse. However, the polymer film 2 used in the polymer film bonding paper 1 of the present embodiment has a small warp accompanying changes in temperature and humidity. Therefore, it becomes easy to manage the temperature and humidity of the warehouse where the polymer film bonding paper 1 is stored.

(Each layer of polymer film paste paper)
As the base paper 5, various papers such as plain paper or various biodegradable plastics can be used. By using such a biodegradable plastic as the base paper, the base paper 5 is easily decomposed even if the polymer film-laminated paper is discarded (landfilled), so that the disposal process becomes easy. Furthermore, in order to suppress the warping of the polymer film-laminated paper 1, it is better to use a multilayer structure base paper as the base paper 5. The thickness of the base paper 5 is preferably 250 to 350 μm.

The adhesive layer 4 is for attaching the polymer film 2 having the aluminum vapor deposition layer 3 formed thereon to the base paper 5 and is made of a cured product of an adhesive previously applied to the aluminum vapor deposition layer 3. Examples of the adhesive include various two-component curable adhesives used for dry lamination, photocurable adhesives, and adhesives used for hot lamination. The two-component curable adhesive is of a type that cures over time, and can be cured in a shorter time by heating. Examples of the two-component curable adhesive include a urethane resin adhesive and an epoxy resin adhesive. The photocurable adhesive is of a type that is cured by irradiation with an electron beam or ultraviolet rays. Examples of the photocurable adhesive include urethane resin adhesives and acrylic resin adhesives. Examples of the adhesive used for hot melt lamination include polyethylene and polypropylene. This thickness of the adhesive layer 4 is not intended to be particularly limited, for example, if the dry lamination is about 1 m ² per 1 to 5 g, preferably a 10~20g per 1 m ² if hot melt lamination.

  The aluminum vapor deposition layer 3 is formed smoothly on the polymer film 2 and is mirror-like and exhibits an excellent metallic luster. It is preferable that the thickness of the aluminum vapor deposition layer 3 is 30-50 nm, for example. The aluminum vapor-deposited layer 3 has a metallic luster as it is, but if the surface is appropriately provided with a hairline pattern, an embossed pattern, a mat pattern, or a hologram pattern, the aluminum vapor-deposited layer 3 is variously formed on the metallic luster. A special pattern is added to exhibit a unique design effect, and the cosmetic property of the polymer film-laminated paper 1 is enhanced, which is preferable. Among these, the embossed pattern and the mat pattern are both matte patterns, and the degree of strength of the metallic luster is appropriately adjusted. Moreover, when a colored layer is appropriately formed on the aluminum vapor-deposited layer 3, the aluminum vapor-deposited layer 3 is colored, a predetermined color is added on the metallic luster, and a specific design effect is exhibited. The cosmetics can be improved. As the colored layer, for example, a transparent or translucent resin in which a pigment such as red, blue, or yellow is dispersed can be used.

  In addition, the aluminum vapor deposition layer 3 is a decoration layer formed in order to improve cosmetics, and is not necessarily limited to this. For example, instead of forming the aluminum vapor deposition layer 3 as a decoration layer, the polymer film 2 may be directly printed to form a printing layer. By forming a printing layer as a decoration layer, various printing can be performed on the polymer film bonding paper 1, and the cosmetic property of the polymer film bonding paper 1 can be improved.

  As the polymer film 2, a nylon film can be used. As a nylon film, the film which consists of nylon 6, nylon 66, nylon 11, or nylon 12, for example is mentioned. As the nylon film, a nylon film having a tensile modulus of 1000 to 2500 MPa is used, but a nylon film having a range of 1000 to 2000 MPa is preferably used, and a nylon film having a range of 1250 to 1750 MPa is more preferable. For example, it is preferable to use a film made of nylon 6 having a tensile modulus of 1500 MPa.

  By using a nylon film having a tensile elastic modulus within the above range, it is possible to effectively suppress the warping of the polymer film-bonded paper 1 during ruled line formation. In addition, it is good for the tensile elasticity modulus of the direction in which more ruled lines are formed among the several ruled lines of the polymer film bonding paper 1 to be in the above range at least. Thereby, the curvature up of the edge part substantially parallel to said one direction of the polymer film bonding paper 1 at the time of ruled line formation can be suppressed. This is because the edge portion substantially parallel to the direction in which more ruled lines are formed in the polymer film bonding paper 1 is greatly warped. The tensile modulus in the other direction is more preferably within the above range. Thereby, the curvature up of the edge part substantially parallel to said other direction of the polymer film bonding paper 1 at the time of ruled line formation can be suppressed.

  Table 1 shows each physical property value of a nylon film suitably used as the polymer film 2 according to this embodiment. In addition, each physical-property value of the nylon film shown in Table 1 is an example to the last, and each physical-property value of the nylon film which concerns on this embodiment is not necessarily limited to this. In Table 1, tensile stress, tensile elastic modulus, tensile strain, bending strength, bending elastic modulus, Charpy impact strength, and Rockwell hardness are shown as physical property values representing mechanical properties. Moreover, the linear expansion coefficient and the deflection temperature under load are shown as physical property values of thermal properties.

  Tensile stress is the tensile force applied to the unit area of the first section (before applying stress) within the distance between the marked lines of the test piece during the test, and “yield” is the increase in strain without increasing the stress. "Fracture" refers to the tensile stress at the time of specimen failure (tensile fracture stress). The tensile strain is the value obtained by dividing the increase in the distance between the marked lines by the initial distance between the marked lines. “Yield” refers to the tensile strain corresponding to the tensile yield stress (tensile yield strain). "" Refers to the tensile strain (tensile fracture strain) corresponding to the tensile fracture stress in the case of fracture without yielding. Bending strength is the maximum bending stress that a specimen can withstand during a bending test. The flexural modulus is a value obtained by dividing the difference between the stresses corresponding to the two specified strains by the difference between the two strains. Rockwell hardness is the net increase in indentation depth when the indenter increases from a defined reference load to a test load and then returns to the reference load. The coefficient of linear expansion is the rate at which the length changes with increasing temperature. The deflection temperature under load is a temperature at which the deflection of the test piece reaches a specified deflection as the temperature rises.

また、表１に示したナイロンフィルム、ＰＥフィルム、ＰＰフィルム、およびＰＥＴフィルムを貼合紙に用いた場合の反り上がりの有無、ならびに各フィルムの物性値（引張弾性率およびシャルピー衝撃強さ）を表２に示す。表２に示すように、ＰＥフィルムおよびＰＥＴフィルムは、引張弾性率が１０００〜２５００ＭＰａの範囲内ではなく、シャルピー衝撃強さも５０〜１５０ｋＪ／ｍ^２の範囲内ではない。そのため、ＰＥフィルムおよびＰＥＴフィルムを用いた貼合紙に対する罫線加工時には反り上がりが生じてしまう。また、ＰＰフィルムは、引張弾性率が１０００〜２５００ＭＰａの範囲内であるが、シャルピー衝撃強さは５０〜１５０ｋＪ／ｍ^２の範囲内ではない。そのため、ＰＰフィルムを用いた貼合紙に対する罫線加工時には反り上がりがやや生じてしまう。これに対してナイロンフィルムは、引張弾性率が１０００〜２５００ＭＰａの範囲内であり、シャルピー衝撃強さも５０〜１５０ｋＪ／ｍ^２の範囲内である。そのため、ナイロンフィルムを用いた貼合紙に対する罫線加工時における反り上がりが抑制される。

Also, the presence or absence of warping when the nylon film, PE film, PP film, and PET film shown in Table 1 were used for the bonding paper, and the physical properties of each film (tensile modulus and Charpy impact strength) It shows in Table 2. As shown in Table 2, the PE film and the PET film have a tensile modulus not in the range of 1000 to 2500 MPa, and the Charpy impact strength is not in the range of 50 to 150 kJ / m ² . Therefore, a warp rises at the time of the ruled line process with respect to the bonding paper using a PE film and a PET film. The PP film has a tensile elastic modulus in the range of 1000 to 2500 MPa, but the Charpy impact strength is not in the range of 50 to 150 kJ / m ² . For this reason, warping is slightly caused at the time of ruled line processing for a laminated paper using a PP film. On the other hand, the nylon film has a tensile elastic modulus in the range of 1000 to 2500 MPa and a Charpy impact strength in the range of 50 to 150 kJ / m ² . Therefore, the warpage at the time of ruled line processing with respect to the bonding paper using the nylon film is suppressed.

(Manufacturing method of polymer film bonding paper)
The polymer film bonding paper 1 can be manufactured as follows, for example. First, aluminum is deposited on the surface of the polymer film 2 by vacuum deposition to form the aluminum deposition layer 3. Then, an adhesive used for the adhesive layer 4 is applied onto the aluminum vapor deposition layer 3. Subsequently, the base paper 5 is overlapped on the adhesive and the whole is bonded (for example, thermocompression bonding), whereby the polymer film 2 on which the aluminum vapor-deposited layer 3 is formed and the base paper 5 are bonded via the adhesive layer 4. It integrates and the polymer film bonding paper 1 is formed.
