TH2101001929A - Bi-directional orientation polyamide film and roll of polyamide film - Google Patents

Abstract

DEPCT64 Bidirectional orientation polyamide film with special mechanical or mechanical properties. good heat Including the S-shaped curl from absorbing moisture after producing bags that are even less It is a product that is near the end of the rolling coil. Bidirectional orientation polyamide film formed by A polyamide resin containing not less than 60% by mass of polyamide 6 as a polyamide film. Bi-directional orientation with the specific characteristics of the molecular orientation angle of the film not less than 20 degrees and the moisture absorption strain not higher than 1.3% and the impact strength not less than 0.8 Joules/15 µm, including the shrinkage rate. With heating after heating at 160 °C for 10 min, it was 0.6 to 3.0% in both the MD direction and the TD direction. ---------------------------------
