PROCESS FOR THE PREPARATION OF THERMOPLASTIC RESIN FILMS

摘要

A method of thermoplastic resin film effecting heat fixation treatment by controlling air injection angle to 30= or more the angle of nozzle outlet to vertical line within the heat fixation zone of the heat treatment device in heat treatment process is disclosed. Thereby, it is possible to provide method for preparing thermoplastic resin film which bending phenomenon like a bow is reduced and transverse property is uniform.
