PROBLEM TO BE SOLVED: To provide a film for deep draw forming which suppresses contraction of a deep-drawn molding portion due to boil sterilization, prevents occurrence of wrinkles on a label stuck before the boil sterilization, and has good pinhole resistance.SOLUTION: There is provided a multilayer film for deep draw forming which has an outermost layer formed of at least one selected from polypropylene, polyamide, polybutylene terephthalate and polyethylene, an intermediate layer containing at least one polyamide resin layer and at least one saponified product layer of an ethylene-vinyl acetate copolymer, a seal inner layer formed of at least one of an ethylene resin and a thermoplastic elastomer, and a seal surface layer containing 50 mass% or more of a polypropylene resin having a melting point of 155°C or higher, where a total thickness of the film is 70 μm or more and 300 μm or less, and a surface layer thickness of the seal layer is 2 μm or more and less than 10 μm.SELECTED DRAWING: Figure 1 |
