  • films made of thermoplastic resin films such as polyethylene and polypropylene have excellent mechanical properties and transparency, and are widely used as packaging materials.

Therefore, various problems are liable to occur, such as the loss of flavor and the content being moistened with moisture from the outside world, resulting in poor mouthfeel. Therefore, usually, a method such as laminating other film layers having good gas barrier properties is often used.

By protecting with layer A, the surface was smoothed and this problem was overcome.
