PURPOSE: To obtain a package having excellent pinhole resistance, shock resistance, flexibility and transparency by using a composite film in which a polyamide resin layer, a resin for bonding as a cushioning material layer, a polyamide resin layer, a resin layer for bonding and a sealant resin layer are laminated in the order from the outside.

CONSTITUTION: A composite film in which a polyamide resin layer A, a resin layer B for bonding as a cushioning material layer, a polyamide resin layer C, a resin layer D for bonding and a sealant resin layer E are laminated in the order from the outside is employed. Nylon 6 is proper as the resin layer A and the copolymer, etc., of nylon 6 and nylon 6-6 as the resin layer C. A monobasic unsaturated fatty acid or an acid modified olefin resin is used as the resin layers B and D. An olefin resin and an ethylene copolymer can be used as the resin layer E.
