Description

[Detailed description of the invention]

According to the present invention, a low-temperature sealant is partially coated at an arbitrary position (a position not in direct contact with the contents) on both sides of a laminated film, and the film is folded in half and both sides are heat-sealed. The present invention also relates to a packaging material for cheese which is provided with an air hole near a fold to form a packaging bag.

2. Description of the Related Art Hitherto, as a packaging material for cheese, K-coated cellophane paper in which a base material is coated with wax or a base material in which a low-temperature sealing sealant is laminated has been proposed.

[0003] However, such conventional packaging materials, particularly those based on cellophane, have low strength and are not suitable for products having a large content. In addition, the entire surface of the substrate is coated or laminated with a sealant,
There is a danger that heat or oil content of the contents penetrates the laminated portion and acts on the adhesive portion or the adhesive layer to cause delamination (the laminated film is peeled off from the adhesive portion).

[0004] The present invention has been made in view of the above situation, and has as its object to provide a cheese packaging material in which only a portion necessary for sealing a particularly heavy cheese or the like can be heat-sealed.

The technical means of the present invention for solving this technical problem is to laminate a heat-sealing film on the entire surface of a synthetic resin film base material to form a laminated film, and to arbitrarily position the laminate film on both sides (at any position). (A position not in direct contact with the contents) is coated partially with a low-temperature sealant, the film is folded in half and both sides are heat-sealed, and an air hole is provided near the fold to form a packaging bag. It is a packaging material for cheese.

[0006] In the cheese packaging material of the present invention, a low-temperature sealant is partially coated at an arbitrary position (a position not in direct contact with the contents) on both sides of the laminated film, so that the heat sealing is performed. (Heat seal)
Thereby, only the parts necessary for bag making and sealing are selectively sealed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a substrate, which is made of a synthetic resin film. The film is not particularly limited, but for example, PET (polyester) or ON (biaxially stretched nylon) is most suitable. Reference numeral 2 denotes an olefin-based film or the like that is generally used as a heat-sealing sealant and is laminated on the entire back surface of the substrate. Reference numeral 3 denotes a low-temperature sealant for coating an arbitrary position on the back surface and an arbitrary position on the front surface (for example, five positions on the back surface and one position on the front surface as shown in the drawing) of the laminated film. Using the packaging material as described above, the packaging material is folded in two and both sides are heat-sealed, and an air hole is provided near the fold to form a packaging bag. The air hole is formed by discharging air from a gap between the bottom surface of the packaging bag and the cardboard box when the packaging bag is mounted on a retainer or a cardboard box having a molding function. It helps to facilitate filling of the filling into the cardboard box. Next, the packaging bag is opened and mounted on a retainer or a cardboard box having a molding function, and the expanded packaging bag is filled with molten cheese. When the melted cheese is filled, the air holes located at the folds (gazettes) in the bottom of the package bag are closed by the heat of the melted cheese, and the coating is melted and the folds are welded and the air holes are closed at the same time. I do. Next, one sealant part on the surface of the packaging material of the packaging bag is turned inside and the other is turned upward, and the cheese is hermetically sealed by being polymerized in a folded manner.

[0008]

As described above, according to the cheese packaging material of the present invention, since the strength is superior to the conventional packaging material, it is possible to fill and package a molten cheese having a large content, for example, 5 to 30 kg. In addition, since the package can be hermetically sealed, there are excellent effects such as prevention of mold generation.
