本発明は、ハム、焼ぶた、魚などの食料品を真空密着包

ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a skin bank packaging material for vacuum tight packaging of foodstuffs such as ham, roasted pork, and fish.

包装材が用いられているか、塩化ビニリチンコート時に
、アイオノマー樹脂とＥＶＡとからなるフィルムの耐熱
性が低いために、充分な熱がかけられず塩化ビニリデン

ン・）′ングで使用不能になるという問題点があった。Conventionally, packaging materials for skin banks have been used in which vinylidene chloride coating is applied to the ionomer resin of a film laminated with ethylene/vinyl acetate copolymer (KvA) on ionomer resin, or when the ionomer resin is coated with vinylidene chloride, the ionomer resin is coated with vinylidene chloride. Due to the low heat resistance of the film made of resin and EVA, sufficient heat cannot be applied and coating with vinylidene chloride is difficult, making it impossible to obtain high barrier properties. However, there were problems with the process of winding the film, and even if it took a long time to use even after being wound to an appropriate hardness, the film would naturally shrink and become unusable due to bronzing.

By laminating VA and ionomer resin in a matte finish, it does not block and can be easily rolled back from the used roll, is easy to manufacture, has stable quality, and is an inexpensive and high barrier '14. The present invention aims to provide a method for manufacturing a skin pack packaging (skin pack) having the following properties.
以１・、本発明の構成を図面に基づいて説明する。1. The configuration of the present invention will be explained based on the drawings.

A polyvinylidene chloride film 2 is formed by coating a plastic film \1 with an emulsion of polyvinylitine chloride and applying heat treatment to form a polyvinylidene chloride film 2. EVA is then extruded and laminated onto this polyvinylidene chloride film 2 to form an EvA layer 6. At the same time as it is formed, the surface of this layer B is given a cloak finish (the surface becomes matte) using a roll with unevenness.

This is a method of forming the layer 6 and the ionomer resin layer 5, and at the same time applying a matte finish to the surface iM7 of the EVA layer B. The total thickness of the EVA layer 3 and the ionomer resin layer 5 is 3
It is 0 to 150μ. The other configurations are the same as in FIG. 1.
本発明の方法により得た包装料でスキンパックする場合
