FORMING METHOD FOR POLYAMIDE FILM

摘要

The method for manufacturing polyamide film, is inflation type method for increasing strength, transparency, adhesiveness to a film of another material. The method is composed of melting polyamide of 3.5-4.0 viscosity, 1.4-1.7 molecular weight; extruding the melt through a ring-shape die for forming a tube type film; cooling the film in the water of 10-40 deg.C temp. and stretching it.
