摘要：
A method for producing a film comprising feeding a composition comprising a crystalline thermoplastic resin having a temperature of higher than the crystallization temperature Tc of the resin to between a first nip-pressing surface and a second nip-pressing surface of a nip-pressing unit, and leading the composition to pass through the nip-pressing surfaces while the nip-pressing unit gives a pressure of from 5 to 1000 MPa to the composition, to thereby form the composition into a film continuously.
