Claims (3)
- 횡연신기내에서의 예열, 연신 및 냉각공정을 포함하는 이축연신 열가소성수지 필름의 제조방법에 있어서, 상기 예열공정중 횡방향 이완율은 3~5%로 하고 횡연신공정중 전반부의 횡연신온도가 후반부 횡연신온도보다 15℃ 이상 높게 하고 전반부에서 전체 횡연신비의 55% 이상을 횡연신하는 것을 특징으로 하는 열가소성수지 필름의 제조방법.
- 제1항에 있어서, 상기 횡연신 전반부의 횡연신온도가 후반부의 횡연신온도보다 약 15-20℃로 높은 것을 특징으로 하는 열가소성수지 필름의 제조방법.
- 제1항에 있어서, 상기 횡연신공정 전반부의 횡연신비가 전체 횡연신비의 60-70% 범위인 것을 특징으로 하는 열가소성수지 필름의 제조방법.
