Method for manufacturing package

Technical Field

The present invention relates to a package for housing articles such as batteries and a method for manufacturing the same.

Background

Conventionally, commodity packages containing articles such as daily sundries including batteries and washing tools and processed foods have been generally used. In this product package, a blister pack (blister pack) is widely used in a container portion from the viewpoint of a store display effect, low cost, and the like. In the commercial package using such a blister pack, a structure is adopted in which a blister pack, a laminate layer (laminate layer), and a backing sheet (backing sheet) are laminated in this order.

More specifically, printing is performed on both sides of the backing sheet, the blister pack and the laminate layer are bonded by hot melt bonding, and then the laminate layer and the backing sheet are bonded with an adhesive. Thus, a complicated laminated structure of the blister package, the laminate layer, the adhesive layer, the print layer, the backing sheet and the print layer is formed.

However, the presence of the adhesive layer has a problem that the structure is complicated and the cost is increased. In particular, since 2 methods are used as the bonding method, the production process is complicated.

Further, considering the influence on the natural environment recently, biodegradable resins which are used in the natural environment and can be decomposed and disappeared with time have been used as materials for commercial packages in place of conventional thermoplastic resins such as polyethylene and polyethylene terephthalate (PET) (for example, Japanese patent laid-open Nos. 10-100353 and 2001-130183). When such a biodegradable resin is used, the temperature range of thermal welding is limited, and therefore, the management thereof is troublesome, and there is a problem that the adhesive strength and quality fluctuate.

In addition, when an adhesive is used, the adhesive strength is actually inferior to that of thermal fusion, and an adhesive suitable for a biodegradable resin has not been found yet.

Recently, it is desired to further improve the packaging of commercial products in terms of simplification of the structure and manufacturing process, reduction of the product cost and manufacturing cost, improvement of the strength and appearance of the packaging of commercial products, and the like. Accordingly, there is a need for improved packages for goods that provide improved laminate structures as described above.

Disclosure of Invention

Accordingly, an object of the present invention is to solve the above-described problems, to simplify the structure and manufacturing process, to reduce the product cost and manufacturing cost, and to obtain a package having excellent strength and appearance.

The present invention relates to a method for manufacturing a package, including the steps of: (1) a step of obtaining a backing plate by successively laminating a 1 st printed layer, a back-surface anti-smudge layer (anti-offset layer) and a 2 nd printed layer on a 1 st surface of a light-transmitting long-sized base material, and (2) a step of holding an article on the 2 nd surface side of the base material on the backing plate.

In the step (2), it is effective to hold the article on the liner by bonding the container in which the article is accommodated to the 2 nd surface. Further, it is also effective to bond the container to the 2 nd surface by thermal welding.

According to the present invention, by providing both the printing layer for viewing from the 1 st surface and the printing layer for viewing from the 2 nd surface on the 1 st surface of the transparent light-transmitting substrate in a simple manufacturing process, it is possible to manufacture a package having a simple structure without a lamination layer and an adhesive layer, and it is possible to reduce the product cost and the manufacturing cost.

Detailed Description

The present invention relates to a method for manufacturing a package, comprising: a light-transmitting substrate; a backing plate including a 1 st printed layer, a back-side smudge-proof layer and a 2 nd printed layer laminated in this order on the 1 st surface of the base material; and a holding means for holding an article on the lining board on the 2 nd surface side of the base material.

First, a case where printing layers are laminated by a conventional printing method will be briefly described.

Fig. 1 is a diagram for explaining a conventional printing method.

As shown in fig. 1, first, in step (a), for example, a roll paper having a length of 1000m as a base material 1 is fed from a roll 2, fed along a roll 3, and printed with the 1 st color, the 2 nd color, the 3 rd color, and the 4 th color by printing rolls 4, 5, 6, and 7, respectively, to form a 1 st printed layer. In addition, 4a, 5a, 6a and 7a are UV lamps for curing UV ink. Then, the second printing of, for example, 4-color ink is performed on the other surface of the base material fed along the roller 3 to form a second printing layer 1. Then, the base material is wound again to form a wound body 8.

Subsequently, in the step (b), the substrate is fed out again from the roll 8, and a back-tack-preventing layer is formed on the upper surface of the 1 st printed layer by a blanket wheel transfer using white ink (using the printing roller 9 and the UV lamp 9a), and the substrate is wound up again to form the roll 10.

Then, in the final step (c), the 2 nd printing layer of, for example, 4 colors is printed on the upper surface of the back-surface-contamination prevention layer while the base material is fed from the roll 10. At this time, the substrate is also fed along the roller 11, and the 1 st, 2 nd, 3 rd and 4 th colors are printed by the printing rollers 14, 15, 16 and 17, respectively, to form the 2 nd printed layer. In addition, 14a, 15a, 16a and 17a are UV lamps for curing UV ink.

When the package of the present invention is produced by the printing method as described above, the following problems occur because the printing steps cannot be continuously performed and the substrate is wound up for each printing step.

As shown in fig. 2(a), a case where a plurality of 1 st printing layers 20 having a length of 120mm, a pitch of 5mm (i.e., a pitch of 125mm), and an arbitrary width are printed on the surface of the long-sized base material 1 is considered. In the 1 st printing, since the long-sized base material is fed out or wound up and further comes into contact with a roller or the like in the printing apparatus, the base material contracts or expands and contracts, and the length thereof tends to fluctuate from 998m (pitch 124.75mm) to 1002m (pitch 125.25 mm).

Here, it is expected that the length of the base material 1 is contracted to 998 m. When the substrate length was reduced to 998m, the pitch of the above-mentioned 1 st printed layer became 124.75 mm. The step (b) is not problematic because the white printed layer is formed as the back-tack prevention layer, but when the step (c) performs the 2 nd printing to form the 2 nd printed layer, the 1 st printed layer 20a and the 2 nd printed layer 21a are shifted by 0.25 mm. On the other hand, in the 100 th print layer, a 25mm offset was generated between the 1 st print layer 20b and the 2 nd print layer 21b, and in the 1000 th print layer, a 250mm offset was generated between the 1 st print layer 20c and the 2 nd print layer 21 c. For the last 8000, a 2m shift is generated between the 1 st printed layer 20d and the 2 nd printed layer 21 d.

That is, when the package of the present invention is produced by a conventional printing method, there is a problem that a shift occurs in printing and it is difficult to improve the yield.

In the present invention, the apparatus shown in fig. 3 is used, and in step (1), the 1 st printing, the flexographic printing, and the 2 nd printing are successively performed on the 1 st surface of the light-transmissive elongated base material 30, and for example, the 1 st printing layer made of 4-color ink, the back-tack-preventing layer made of white ink, and the 2 nd printing layer made of 3 colors are successively superimposed to obtain a backing sheet. Then, in step (2), a package is produced by holding an article on the liner on the 2 nd surface side of the base material.

Accordingly, the number of steps for winding the substrate is reduced, and the substrate does not slip even in the printing apparatus, so that the shrinkage and the elongation can be minimized, and the yield can be improved.

More specifically, as shown in fig. 3, the longitudinal base material 30 is fed along the roller 33, and the 1 st, 2 nd, 3 rd and 4 th color inks are printed by, for example, printing rollers 34, 35, 36 and 37, respectively, to form the 1 st printing layer composed of the 4-color ink. UV lamps 34a, 35a, 36a and 37a are provided behind each printing roller to allow the UV ink to be cured.

The substrate 30 is then fed as is to the flexographic roller transfer roller 40, a back smudge-resistant layer comprised of white ink is formed using the UV lamp 40a, and the substrate 30 is fed as is along the roller 41, for example, printing of 1 st, 2 nd and 3 rd color inks by printing rollers 44, 45 and 46, respectively, to form a 2 nd printed layer comprised of 3 rd color ink. UV lamps 44a, 45a and 46a are provided behind each printing roller to allow the UV ink to be cured. Then, the final base material 30 is wound up to form a wound body 48.

The 1 st and 2 nd printing layers are preferably formed by relief printing or gravure printing, but relief printing is more preferred from the viewpoint of enabling printing with a predetermined fineness. Further, the back-tack prevention layer is preferably formed by flexographic printing or screen printing, but from the viewpoint of speed and mass production, flexographic printing is preferable.

Here, the package of the present invention will be described with reference to the drawings.

Fig. 4 is an exploded perspective view schematically showing one embodiment of the package of the present invention. As shown in fig. 4, the package 101 of the present invention includes a patch 102, a battery pack 104 as a product, and a container 103 holding the battery pack 104 on the patch.

Next, fig. 5 is a longitudinal sectional view when the package shown in fig. 4 is assembled. As shown in fig. 5, the package 101 of the present invention has: a backing sheet 102 comprising a light-transmitting base material 102a, and a 1 st printed layer 102b, a back-surface-contamination-preventing layer 102c, and a 2 nd printed layer 102d laminated in this order on the 1 st surface of the base material 102 a. Further, on the 2 nd surface side of the base member 102a, a container 103 as a holding means for holding the battery pack 104 on the backing plate 102 is provided.

In the conventional package, the front surface and the back surface of the base material are printed separately, but in the package of the present invention, only one surface is printed. On the 1 st surface of the light-transmitting (transparent) base material 102a, both the 2 nd printed layer 102d for viewing from the back surface side of the backing sheet and the 1 st printed layer 102b for viewing from the front surface side of the backing sheet are provided.

That is, in the package of the present invention, printing for design, explanatory characters, and the like viewed from the directions of arrows X and Y shown in fig. 5 is provided on the 1 st surface of the base material 102 a. This makes it possible to omit the lamination layer and the adhesive layer provided between the conventional container 103 and the base material 102 a.

Then, back-tack prevention layer 102c is provided between 1 st printed layer 102b and 2 nd printed layer 102d so that 1 st printed layer 102b is not seen from the direction of arrow Y or, conversely, 2 nd printed layer 102d is not seen from the direction of arrow X (i.e., back-tack does not occur). The back-surface contamination prevention layer 102c may have a masking effect to such an extent that, for example, a barcode included in the 1 st printed layer 102d can be read.

The 1 st printing layer 102b and the 2 nd printing layer 102d are formed using a normal ink such as an ultraviolet curable (UV) ink, for example. The thickness of the 1 st printed layer 102b and the 2 nd printed layer 102d is about 4.0 to 6.0 μm.

On the other hand, the back smudge preventing layer 102c may be formed of the same ink as the 1 st printed layer 102b and the 2 nd printed layer 102d, but the thickness and composition thereof may be controlled within the range in which the above-described shielding effect is exhibited. For example, the ink is preferably formed of a white UV ink having a thickness of 10.0 to 15.0 μm and having no light transmittance.

The 1 st and 2 nd printing layers 102b and 102d are preferably formed by relief printing or gravure printing, but the backside offset prevention layer 102c is preferably formed by flexographic printing, having a predetermined thickness and exhibiting the above-described shielding effect.

Then, the container 103 and the base 102a of the backing 102 are bonded by hot melt bonding to be integrated, whereby the battery pack 104 is held on the backing 102 on the 2 nd surface side of the base 102 a. Further, the liner 102 may be provided with a hanging hole 105 so that the package 101 can be hung and displayed on a sales counter or the like.

The liner plate 102 of the present invention as described above can be applied to other packages.

Fig. 6 is an exploded perspective view schematically showing another embodiment of the package of the present invention.

The package 111 shown in fig. 6 is composed of a liner 112 and a transparent container 113, and a battery pack 114 is housed in the container 113.

In this embodiment, the same liner as the liner 102 in fig. 4 and 5 can be used as the liner 112. Thus, there is no lamination layer and adhesive layer on the surface of the liner 112 facing the container 113, but beads 113a, 113b and 113c may be provided on the portion of the container 113 opposite the receptacle.

That is, the peripheral portion of the container 113 is curled 180 degrees toward the base 112 side to form the curled portion, and the liner 112 is slid and inserted from the end portions of the curled portions 113a and 113c in the direction of the chain line (arrow Z) to reach the curled portion 113b, whereby the liner 112 and the container 113 can be integrated.

Since the liner 112 is merely sandwiched between the beading portions 113a, 113b and 113c of the container 113, it is preferable to fix the liner 112 and the beading portions 113a, 113b and 113 c. The fixing means is not particularly limited, and examples thereof include heat welding, adhesives, and staplers, but heat welding is preferable.

Further, as in the case of fig. 4 and 5, the liner 112 may be provided with a hanging hole 115 so that the package 111 can be hung and displayed on a sales counter or the like.

In the packages 101 and 111 shown in fig. 4 to 6, the base material constituting the backing 102 is transparent, but in order to allow the consumer to further see the pattern printed on the battery outer seals in the battery packs 104 and 114, the containers 103 and 113 are preferably also transparent.

The liner of the present invention can be applied not only to the packages using blister packs shown in fig. 4 to 6, but also to so-called film packages (also called skin packages) and shrink packages (shrink packages).

Here, in the package of the present invention, either the base material or the container is preferably made of a biodegradable resin.

Examples of the biodegradable resin that can be used in the present invention include aliphatic polyesters, modified polyvinyl alcohol (PVA), cellulose ester compounds, and modified starch products, among which aliphatic polyesters are preferable from the viewpoint of environment because the toxicity of alcohol and carboxylic acid generated during decomposition is extremely low.

Further, examples of the aliphatic polyester include a hydroxybutyric acid-valeric acid polymer which is a microorganism-producing polymer, a polycaprolactone which is a synthetic polymer, and an aliphatic dicarboxylic acid-aliphatic diol condensate, and a polylactic acid polymer which is a semi-synthetic polymer.

The polylactic acid polymer is preferably used because it is excellent in transparency, rigidity, heat resistance and processability. The polylactic acid polymer may be a homopolymer of L-lactic acid and/or D-lactic acid, but may be a copolymer or a mixture (or a polymer alloy) with another hydroxycarboxylic acid as long as the effect of biodegradability is not impaired.

Examples of the other hydroxycarboxylic acids include glycolic acid, 3-hydroxybutyric acid, 4-hydroxybutyric acid, 3-hydroxyvaleric acid, 4-hydroxyvaleric acid, and 6-hydroxyhexanoic acid.

The polylactic acid polymer as a preferred biodegradable resin preferably has a weight average molecular weight in the range of 50,000 to 300,000. Although the present invention is not limited thereto, when the weight average molecular weight is less than 50,000, practical physical properties are hardly exhibited, whereas when the weight average molecular weight is more than 300,000, the melt viscosity becomes too high, and the molding processability tends to deteriorate.

In addition, polylactic acid polymers have high glass transition temperature and crystallinity, and have properties similar to PET. More preferably, a film made of polylactic acid can be uniaxially or biaxially stretched, and a stretched sheet having molecular orientation, low brittleness, difficulty in cracking, and extremely excellent strength can be obtained. Further, extrusion and casting processes can be performed, and transparency can be secured. As will be described later, in the present invention, particularly when the container is formed by the air-pressure molding, the stretched sheet is preferably used as the material.

As a raw material of the polylactic acid polymer, corn can be used. Starch is separated from corn and saccharified, lactic acid is obtained by lactic acid fermentation, and polylactic acid is obtained by polymerization through lactide. Since the polylactic acid polymer can be obtained from a raw material other than the petroleum-based raw material, the final battery pack itself is not limited to the present invention, and it is also considered that the production process of the raw material is environmentally friendly.

The biodegradable resin can also be used as a resin composition. In this case, the polymer may be mixed with another polymer material within a range not impairing the effects of the present invention. For the purpose of adjusting physical properties and processability, a plasticizer, a lubricant, an inorganic filler, an ultraviolet absorber, a heat stabilizer, a light absorber, a colorant, a pigment, a modifier, and the like may be blended.

Here, in the container portion of the package, it is particularly necessary to form a housing portion having a relatively fine shape such as an angular portion in accordance with the shape of the battery, and it is particularly required to have transparency and moldability. Since the biodegradable resin is brittle, there is a problem that cracking occurs when the biodegradable resin is molded under conventional conditions.

In order to solve this problem, in the present invention, in order to obtain the container, it is particularly preferable to use a stretched sheet of a biodegradable resin. By virtue of this stretching, the brittleness and strength of the resulting sheet can be improved, and a container having a strong crack resistance can be produced. Biaxially stretched sheets have higher strength than uniaxially stretched sheets and are therefore preferable. The stretched sheet can then be formed into the shape of a container in a conventional manner.

The tensile properties (tensile breaking strength) of the above stretched sheet are preferably 40 to 90 MPa. When the tensile rupture strength of the stretched sheet is less than 40MPa, the strength that can be maintained in the battery cannot be obtained, while when it is more than 90MPa, the tensile sheet strength is too high, and moldability on the molding surface is deteriorated, and transparency of the sheet is also deteriorated. The tensile breaking strength is more preferably 60 to 80 MPa. The tensile properties in the present invention were measured at a test speed of 200mm/min using a type 2 test piece in accordance with JIS K-7127.

The tensile modulus of the stretched sheet is preferably 1 to 7 GPa. When the tensile modulus of elasticity of the stretched sheet is less than 1GPa, the sheet becomes too hard and the moldability on the molding surface is reduced, while when it is more than 7GPa, the sheet becomes too soft and the battery is difficult to hold. The tensile elastic modulus is more preferably 2 to 6 GPa. The tensile modulus of elasticity can be measured in accordance with JIS K-7127.

The haze, which is an index indicating the transparency of the stretched sheet, is preferably less than 15%. When the haze is 15% or more, the transparency of the sheet is lowered, and the original function of the package cannot be exhibited. The turbidity is more preferably 2 to 12%. The haze can be measured by using JIS K-7105 as a standard.

In addition, the container may contain a battery pack in which a shrink package containing a plurality of batteries as articles is used. The shrink wrap is also preferably made of biodegradable aliphatic polyester. The biodegradable aliphatic polyester is preferably a polylactic acid polymer, and the shrink wrap is preferably formed of a stretched sheet of a biodegradable aliphatic polyester.

In addition, the thickness of the base material in the package of the present invention is preferably 50 to 200. mu.m. When the thickness of the substrate is less than 50 μm, the substrate is too thin to hold the article, and when it is more than 200 μm, the thermal conductivity is lowered, the adhesive strength is fluctuated, and the packaging quality tends to be lowered in the case of thermally fusing the substrate and the container. In addition, it is difficult to perform heat management at the time of heat welding.

Examples

The present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

EXAMPLE 1

In this example, a printing apparatus having the structure shown in fig. 3 was used to produce the package of the present invention having the structure shown in fig. 4 and 5.

As the light-transmitting substrate 102a, a translucent stretched sheet (tensile properties (tensile breaking strength) of 110MPa in the machine direction and 110MPa in the transverse direction, and tensile elastic moduli of 3.8GPa in the machine direction and 4.3GPa in the transverse direction) composed of polylactic acid (PLA) having a thickness of 150 μm was prepared. The heat shrinkage was measured by heating the test piece at 120 ℃ for 5 minutes in accordance with JIS Z1712, and the results were 2.7% in the machine direction and 0.3% in the transverse direction.

On one side of the base material 102a, a 1 st printing layer 102b having a thickness of 5 μm using UV ink by letterpress printing, a back smudge preventing layer 102c having a thickness of 12 μm formed by UV ink by flexographic printing, and a 2 nd printing layer 102d having a thickness of 5 μm formed by letterpress printing were formed by one-pass rotary printing so as to be successively coated. Thus, the backing plate 102 is obtained.

Next, a transparent stretched sheet (tensile properties (tensile breaking strength): 66MPa in the machine direction and 65MPa in the transverse direction, tensile moduli: 3.2GPa in the machine direction and 3.1GPa in the transverse direction, haze: 10%) made of 250 μm PLA was prepared. The heat shrinkage of the stretched sheet was measured by heating the test piece at 120 ℃ for 5 minutes in accordance with JIS Z1712, and found to be 3.7% in the longitudinal direction and 1.7% in the transverse direction. The stretched sheet is formed to obtain a container 103 having a shape shown in fig. 4 and 5.

Finally, a battery pack (shrink-wrap) 104 including 4 single-three cylindrical batteries was prepared, and was stored in the storage portion of the container 103, and the flange portion of the container 103 and the base material 102a of the liner 102 were bonded by thermal fusion bonding at a heating temperature of 100 ℃.

EXAMPLE 2

The package B of the present invention was produced in the same manner as in example 1 except that the base 102a and the container 103 of the gusset 102 were formed of a polyethylene terephthalate (PET) stretched sheet (having a tensile property (tensile breaking strength) of 68MPa in the machine direction and 68MPa in the transverse direction, a tensile elastic modulus of 2.1GPa in the machine direction and 2.2GPa in the transverse direction, and a haze of less than 1%) instead of a PLA stretched sheet.

Comparative example 1

A 1 st printed layer was formed on the 2 nd surface of the base 102a by letterpress printing, and a transparent stretched sheet of 50 μm thick PLA as a laminate layer was bonded to the 1 st printed layer with a polyamide adhesive. The 2 nd printed layer is then provided on the 1 st side of the substrate 102a by letterpress printing. The laminate layer and container are then bonded by hot melt application. Otherwise, a comparative package C was obtained in the same manner as in example 1.

Comparative example 2

A comparative package D was obtained in the same manner as in example 1, except that the back pick-up preventing layer formed by flexographic printing was not provided.

[ evaluation ]

(1) Peel strength

As shown in fig. 7, first, a liner side test piece 121 obtained by cutting a liner of each package into a rectangle having a width of 10mm and a container test piece 122 obtained by cutting a stretched sheet constituting a container of each package into a rectangle were bonded to each other at a portion 123 by heat welding, and the length of the portion 123 was about 6 mm. Fig. 7 shows a pattern of a test piece for evaluating peel strength.

Then, a T-peel test was performed by pulling both ends of the test piece in opposite directions at a speed of 200mm/min as shown in FIG. 7 using a digital dynamometer manufactured by IMADA, and the strength necessary for peeling was measured. The results are shown in Table 1. The larger the value, the higher the peel strength and the more preferable.

(2) Wear resistance

Here, the abrasion resistance of the back surface of the liner 102 (the 1 st surface side of the base 102 a), that is, the surface not bonded to the container 103 was evaluated. As shown in fig. 8, a plate-like corrugated paper 125 similar to an outer case used for carrying a battery pack is attached to a weight 124 having a weight of 0.9kg, thereby obtaining a slider 126. Fig. 8 is a diagram showing a pattern for evaluating wear resistance.

Then, the lining board 102 of each package was fixed, and the slider 126 was reciprocated 500 times, and the case where the characters of the 2 nd printed layer were clearly visible, the case where the characters were slightly less visible, and the case where the characters were less visible and were not visually recognizable was marked as x. The results are shown in Table 1.

(3) Degree of back surface fouling

With respect to the packages a to D, whether or not the 2 nd printed layer and the 2 nd printed layer were stained on the back surface was observed by naked eyes from the front surface side and the back surface side, respectively. The case where there was no back surface stain was rated as "good", the case where there was only a little back surface stain was rated as "Δ", and the case where the degree of back surface stain was large was rated as "x". The results are shown in Table 1.

TABLE 1

Table 1 shows the results of evaluation of the liner structure, peel strength, abrasion resistance, and degree of back-surface offset in the packages a to D. As can be seen from table 1, the packages a and B of the present invention of examples 1 and 2 are excellent in general performance.

The package of the present invention having excellent strength and abrasion resistance can be produced by a simpler method than the conventional one, and can be effectively used as a package for storing various articles and hanging them at a store in addition to storing batteries. In particular, since a biodegradable resin can be used as a material, it is preferable as an environment-friendly package.
