BEST MODE FOR CARRYING OUT THE INVENTION
The package of the present invention will be described in detail below based on one embodiment.
In the package of the present invention, for example, as shown in FIG. 1, a base film (11), a buffer layer (12), a barrier layer (13), and a sealant layer (14) are sequentially arranged from the outside toward the inside. This is a package (1) in which a composite film (10) laminated in order is formed into a bag shape, an aggregate (20) of solids such as granules is housed inside, and degassed or vacuum packaged.
[0017]
As the base film (11), a PET film or an ONy film excellent in toughness and piercing resistance, or a laminated film containing the PET film or the ONy film can be preferably used.
The preferred thickness of the base film (11) is about 25 μm for a PET film and about 15 μm for an ONy film.
[0018]
The buffer layer (12) is a layer that absorbs irregularities on the surface of the aggregate having irregularities on the surface such as coffee beans and the like, and is made of a nonwoven fabric (for example, a polyester resin-based Elves (manufactured by Unitika Ltd.), a basis weight of 20 to 30 g / m 2 ), a foamed plastic film (for example, polypropylene resin-based Sanipearl (manufactured by Mitsui Chemicals Platech Co., Ltd.), thickness 100 μm), a foamed plastic sheet (for example, a polypropylene resin-based P board (manufactured by JSP Corporation), A synthetic paper (for example, polypropylene resin-based YUPO (manufactured by Oji Yuka Synthetic Paper Co., Ltd.), a thickness of 80 μm) can be preferably used.
[0019]
The barrier layer (13) is a layer that imparts gas barrier properties, and is a metal obtained by depositing a thin film of a metal such as aluminum on a stretched film such as an aluminum foil or a uniaxially or biaxially stretched PET film, a polyamide film, or a polyolefin film. An inorganic compound vapor-deposited plastic film or a plastic film as described above in which a thin film of an inorganic compound such as aluminum oxide or silicon oxide is provided on a stretched film such as a vapor-deposited plastic film, a uniaxially or biaxially stretched PET film, a polyamide film, or a polyolefin film. A barrier-layer-coated plastic film obtained by applying a suitable amount of a mixture of a vinylidene chloride resin, an inorganic layer compound, and a water-soluble polymer such as polyvinyl alcohol to the film can be preferably used.
Alternatively, a laminated film containing any of an aluminum foil, a metal-deposited plastic film, an inorganic compound-deposited plastic film, and a barrier layer-coated plastic film can be preferably used.
[0020]
The sealant layer (14) is a layer for imparting heat sealing property to the package, and a polyolefin resin such as a polyethylene resin or a polypropylene resin can be suitably used.
[0021]
These layers are laminated to form a composite film (10), but the method of laminating each layer is not particularly limited, and a method of dry lamination via a two-component reaction type polyester resin adhesive (not shown) is preferable. Can be used.
This lamination method does not require lamination in a pattern, so that a composite film can be efficiently produced.
[0022]
The composite film (10) thus produced is slit into a desired size to make a bag. The shape of the bag is arbitrary such as a two-sided seal bag, a three-sided seal bag, a four-sided seal bag. Many.
[0023]
A prescribed amount of coffee beans and tea leaves are put in the completed gusset bag, and the bag is evacuated or vacuum-packaged. Alternatively, a gas absorbent, for example, an oxygen absorbent or a carbon dioxide absorbent is sealed and packaged under reduced pressure. Thus, the package of the present invention is manufactured.
In this package, since the cushioning layer is provided on the packaging bag, the irregularities on the surface of the aggregate that is the content are not absorbed by the buffer layer, and the shape of the irregularities of the content does not appear on the surface.
Moreover, since the gas barrier property is excellent, the package which has been degassed or vacuum-packaged can withstand long-term storage.
[0024]
【The invention's effect】
As described above, the package of the present invention uses a bag made of a composite film in which a base film, a buffer layer, a barrier layer, and a sealant layer are sequentially laminated using a lamination method such as a dry lamination method. Unevenness of the aggregate of solids, which is the content, does not appear on the surface of the bag, and a package with good yield and work efficiency can be manufactured.
