Abstract

폴리아미드 6 수지를 시트상으로 압출하고 냉각하여 폴리아미드 6 베이스 필름(base film)을 제조하고 종, 횡방향 연신한 다음, 횡방향 이완 열처리하고 종방향 이완 열처리한 폴리아미드 62축 연신 필름은 열수축율이 적을 뿐만 아니라 종방향과 횡방향의 수축비가 1:1∼1:1.6로서 균형을 이룸으로서 이를 포장 가공재로 사용할 시열처리하여도 비틀림이나 불균일 등과 같은 현상을 방지할 수 있다.The polyamide 6 base film was extruded into a sheet and cooled to prepare a polyamide 6 base film, longitudinally and laterally stretched, and then the transversely relaxed heat treated and longitudinally relaxed heat treated polyamide 62-axis stretched film was heated. Not only is the shrinkage rate low but also the ratio of the shrinkage ratio in the longitudinal and lateral directions is 1: 1 to 1: 1.6, which can prevent phenomena such as torsion or non-uniformity even when the heat treatment is used as a packaging material.
