Biaxially stretched multilayer film |
摘要 |
<p>A biaxially stretched multilayer film suitable for packaging a processed food product is formed of a biaxially stretched laminate film of at least three layers including a pair of outer layers each comprising a thermoplastic resin, and an intermediate layer disposed between the outer layers. The intermediate layer comprises a polyamide resin composition comprising an aromatic diamine copolymer and an aromatic diamine polymer, and at least one of the outer layers comprises a polypropylene resin. The multilayer film shows a good balance among formability, heat-shrinkability, easy-sealability, gas-barrier characteristic, moisture-barrier characteristic and softness, and also good heat-resistance adapted to retort sterilization.</p> |
