PROBLEM TO BE SOLVED: To provide an inexpensive multilayer film for deep-drawing packaging, preventing effects by humidity, having excellent pinhole resistance during freezing distribution and capable of suppressing generation of curls during boil sterilization.SOLUTION: A multilayer film for deep-drawing packaging is formed by laminating five or more layers of at least an outer layer, an adhesive layer, a gas barrier layer, an adhesive layer and a heat seal layer in this order. In the multilayer film for deep-drawing packaging, the outer layer is composed of polyethylene blended with 5-40 wt.% of thermoplastic elastomer. |
