Description

저수축성 폴리에스테르 필름의 제조방법Manufacturing method of low shrinkage polyester film

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도 및 제2도는 각각 필름단부 및 필름면 내의 평면성이 악화된 선행 필름의 개요도.1 and 2 are schematic views of a preceding film having deteriorated planarity in the film end and film plane, respectively.

Claims (1)

150℃ 분위기에 2시간 방치시킨 경우의 필름수축율이 0.8% 이하인 폴리에스테르 필름을 여러장 중첩하고, 150℃ 내지 220℃의 로(爐) 내에서 열처리함을 특징으로 하는 150℃ 분위기에 2시간 방치시킨 경우의 수축율이 0.1% 이하인 저수축 폴리에스테르 필름의 제조방법.Two sheets of polyester film having a film shrinkage of 0.8% or less when they are left to stand at 150 ° C. for 2 hours are superimposed and heat-treated in a furnace at 150 ° C. to 220 ° C. for 2 hours in a 150 ° C. atmosphere. The manufacturing method of the low shrinkage polyester film whose shrinkage ratio at the time of making it is 0.1% or less. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
