である。Further, the outermost layer has a Young's modulus of 50
It is preferable to use a CPP film in a range of up to 90 kg / cm 2 (measurement method: based on JIS K7127),
Since Young's modulus film is stretchy during lamination is less than 50 kg / cm 2, becomes distorted easily cause curling or waving during boiling treatment, 90 kg / cm 2
In the case of a film having a thickness of more than, there is a tendency that a waving phenomenon due to the boil processing is likely to occur. Also, as the co-extruded composite film used for the co-extruded composite film layer, composite films having various layer configurations can be used, and a heat seal layer, an intermediate layer made of a polyamide resin for imparting pinhole resistance and moldability. When a gas barrier property is required, a composite film containing an ethylene-vinyl alcohol copolymer (hereinafter referred to as "EVOH") is obtained.
