2. Description of the Related Art Conventionally, a mount for blister packaging (300)
Is a hot melt adhesive layer (34) as shown in FIG.
0) / plastic film layer (330) / aluminum foil layer (320) / backing material base layer (310) is generally used. For example, a single art paper having a basis weight of 84.9 g / m ² is used. A base material layer, a 7 μm-thick aluminum foil as a barrier layer was laminated on the upper surface by a wet lamination method, and a 9 μm-thick stretched polyethylene terephthalate film was laminated on the aluminum foil layer surface of the laminate by a dry lamination method. ,
The laminate obtained by applying a modified wax-based adhesive at a coating amount of 30 g / m ^{2 on} the polyethylene terephthalate film layer surface was used. The printing was performed on the lower surface of the mount substrate layer and the upper surface of the aluminum foil layer. Also, in the blister packaging, the content to be stored is placed at a predetermined position on the mount for the blister packaging, covered with a cover made of vinyl chloride sheet-formed to fit the shape of the content, and the periphery of the cover is covered. And the periphery of the blister packaging board are sealed by heat sealing.

[0003]

However, since the above-mentioned conventional blister packaging board is made of paper as a base material layer, it has a problem that it easily curls according to aging and environmental conditions, and aluminum foil is used for a barrier layer. Therefore, there is a problem that aluminum foil is agglomerated and damages the incinerator at the time of disposal by scraping off the backing paper at the time of producing the package or burning the package after use. The present invention, in response to a request to solve the above-mentioned problems of the conventional blister packaging board, provides a blister packaging board that has less curl due to aging and environmental conditions and less damage to the incinerator during disposal. is there.

[0004]

A solution for the present invention, as shown in FIG. 1, the mount to be used for blister packaging, 該台paper
In but a basis weight of 80 g / m @ 2 or more paper substrate layer, a barrier layer, an inorganic oxide or blister packaging backing, wherein a deposition thin film layer of a metal plastic film layer which was provided (120) was laminated (100).

[0005] depositing a thin film layer described above are intended to be formed by vacuum deposition, sputtering, a known method such as ion plating, vapor deposition thin film layer of an inorganic oxide, silicon oxide (Si _x O _{y: x} = 1 or 2, y = 0 to 3) or a deposited thin film layer of magnesium oxide (MgO) or the like;
The metal deposited thin film layer is a deposited thin film layer of aluminum or the like.

[0006] In the constituent layers of the blister packaging board of the present invention, a plastic film layer can be formed on a paper base layer having a basis weight of 80 g / m2 or more without using aluminum foil as a barrier layer as in the past. Has a vapor deposited thin film layer of an inorganic oxide or a vapor deposited layer of aluminum, so that oxygen permeability and water vapor permeability are low, and the stored contents have good storage stability.

Further, a plastic film layer on which an inorganic oxide vapor-deposited thin film layer or an aluminum vapor-deposited thin film layer is formed has a dead-hold property (a property of maintaining a shape and is hard to return once curled) like an aluminum foil.
And curl degree corresponding to aging and environmental conditions is small.

Further, when the used package is disposed of by incineration, since the aluminum foil is not used in the constituent layers unlike the conventional mount for blister packaging, the package becomes a lump and the incinerator is formed. No damage.

[0009]

EXAMPLES Example 1 First, the hot melt adhesive layer (140) shown in FIG.
A mount for blister packaging (100) of this example having a configuration of a plastic film layer (130) / a vapor-deposited thin film layer of inorganic oxide (120) / a mount substrate layer (110) was prepared. The specific method will be described in more detail.
g / m ² of art paper as the backing substrate layer,
400Å thick deposited thin layer of silicon oxide as a barrier layer: a (Si _x O _{y x} = 1 or 2, y = 0 to 3) of 12μm thickness was formed on one side by vacuum deposition oriented polyethylene terephthalate film, the oxide Laminated by dry lamination so that the silicon deposition surfaces are bonded together,
Further, a modified wax-based adhesive having an application amount of 30 g / m ² was applied to the surface of the polyethylene terephthalate film layer of the laminate. Printing was performed by gravure printing on both the front and back surfaces of the backing substrate layer.

Next, as shown in FIG. 4, a chocolate confectionery is placed as a content (30) to be stored at a predetermined position on the blister packaging board (100) of the present embodiment thus produced. 1 formed into a sheet according to the shape of the contents
20 μm thick (average thickness) lid material made of vinyl chloride (20)
Then, the mating portion between the peripheral edge of the lid material and the peripheral edge of the blister packaging mount was heat-sealed and sealed to produce a blister package (10) according to the present example. At the same time, for comparison and evaluation, as a conventional example, a modified wax-based adhesive having an application amount of 30 g / m ² , a stretched polyethylene terephthalate film having a thickness of 9 μm, an aluminum foil having a thickness of 7 μm, and a basis weight of 84. A blister package containing the contents was produced in the same manner as in this example using a 9 g / m ² single-art paper blister packaging mount. The printing is
Gravure printing was performed on the lower surface of the backing substrate layer and the upper surface of the aluminum foil layer.

Next, in order to compare and evaluate the degree of curling with time and storage conditions of the blister package using the mount of the present embodiment and the conventional blister package using the mount, 20 blister packages were used for 4 weeks each. The package was stored indoors and in a thermo-hygrostat, and the curled state of the package was observed over time. The result is shown in FIG. The curl amount was represented by the sum of the curl lengths (a, b) at both ends of the package shown in FIG. 5, that is, the sum of a and b.

The results of FIG. 6 show that the degree of curling of the blister package using the mount of the present embodiment is lower than that of the conventional blister package using the mount when the storage period is two weeks. In the 4th week, it was 56% smaller in the room and 28% smaller in the room in the constant temperature and humidity chamber.

Further, the barrier properties of the backing sheet of this embodiment were measured. The oxygen permeability was ² cc / m ² · 24 hrs · atm, and the water vapor permeability was 2 g / m ² · 24 hrs. This value does not adversely affect the contents in normal use, based on past knowledge.

[0014] In addition, the used package and the scraps of the backing paper used in the production of the packaging body are discarded by incineration. However, aluminum foil is used in the constituent layers as in the conventional blister packaging backing paper. They did not lump and damage the incinerator.

Example 2 First, the hot melt adhesive layer (240) shown in FIG.
A mount (200) for the blister packaging of this example having a configuration of a plastic film layer (230) / aluminum vapor-deposited thin film layer (220) / mount base material layer (210) was prepared. The specific method will be described in more detail.
g / m ² of art paper as the backing substrate layer,
A 12 μm-thick stretched polyethylene terephthalate film in which a 400 ° -thick aluminum vapor-deposited thin film layer was formed on one side by a vacuum vapor-deposition method as a barrier layer was laminated by a dry lamination method so that the aluminum vapor-deposited surfaces were bonded. A modified wax-based adhesive having a coating amount of 30 g / m ² was applied to the surface of the polyethylene terephthalate film layer. Printing was performed by gravure printing on both the front and back surfaces of the backing substrate layer.

Next, as shown in FIG. 4, a chocolate confectionery is placed as a content (30) to be stored at a predetermined position on the blister packaging mount (200) of the present embodiment, which is prepared. 1 formed into a sheet according to the shape of the contents
20 μm thick (average thickness) lid material made of vinyl chloride (20)
Then, the mating portion between the peripheral edge of the lid material and the peripheral edge of the blister packaging mount was heat-sealed and sealed to produce a blister package (10) according to the present example.

Next, in order to compare and evaluate the degree of curl between the blister package using the mount of the present embodiment and the blister package using the conventional mount, 20 pieces of the blister package were allowed to stand indoors and to be kept at a constant temperature for 4 weeks. The package was stored in a constant-humidity bath and the curled state of the package was observed. As a result, the degree of curling of the package according to the present example was smaller than that of the conventional package, as in Example 1. Also, the barrier properties did not impair the contents in normal use. Furthermore, the used package and the scraps of the backing paper used during the production of the packaging body were discarded by incineration, but the aluminum foil was not used in the constituent layers, unlike the conventional blister packaging backing paper. But did not lump and hurt the incinerator.

The blister package using the blister packaging sheet of the present invention is a paper base material having a basis weight of 80 g / m 2 or more.
