원인 분석
There is material hang-up or damage at a certain point of the die lip; material residence time at that point differs, causing local degradation and forming a linear defect.
해결 방법
Clean and polish the die lip and check for scratches; adjust the die lip temperature at that point; use a melt pump to stabilize pressure.
핵심 요약
PET linear gel particles point to a problem at a specific die lip position.
