The composite film provides a polypropylene or other base resin layer and the base material and the first coating layer of the resin composition (1) containing the following components (A), (B), (C) and (D) on one side of the base resin layer: It is provided by laminating | stacking the 2nd coating layer of the resin composition (2) containing the following component (A) and (D) to another name of a resin layer, and the said composite film is extended | stretched arbitrarily. The resin composition (2) may contain component (C).n n n (A) heat sealable olefin polymer (for example, propylene copolymer such as propylene-ethylene copolymer, propylene-butene-1 copolymer, or propylene-ethylene-butene-1 copolymer),n n n (B) diorganopolysiloxanes (eg, dimethylpolysiloxanes),n n n (C) fine powder of heat resistant resin (for example, spherical fine powder of thermosetting resin),n n n (D) higher fatty acid amides.n n n Such a composite film is excellent in slipperiness, antistatic property, mold release property and transparency, and has aptitude with an automatic packaging machine for high speed overlapping. |
