PURPOSE:To provide a composite film for deep draw forming, which can be used for the packaging of a steam shrinkage type and from which a package having excellent appearance is obtained. CONSTITUTION:An external layer is composed of nylon 6 and an internal layer of polyolefin, an intermediate layer is constituted of a resin, in which amorphous nylon (nylon 6T/6I) is mixed with nylon 6/66, and a composite film, in which the thickness of the external layer is reduced to half or less of the intermediate layer while the total thickness of the external layer and the intermediate layer is kept within a range of 30-100mum, is used. A package having excellent moldability and superior appearance is acquired by the combination of the layer (the external layer) of nylon 6 and an amorphous nylon mixed layer (the intermediate layer). |
