EEA film blocking, difficult delamination
문제 현상
EEA film interlayer blocking force >5N/15mm, automatic slitting machine cannot delaminate
원인 분석
EEA surface adhesion strong; film temperature too high >40°C during winding; low molecular substances migrating to the surface forming an adhesive layer
해결 방법
1) Add 0.3-0.5wt% antiblock agent erucamide; 2) Fully cool to <25°C before winding; 3) Add 0.2wt% slip agent to synergistically reduce blocking; 4) Reduce winding tension to reduce interlayer pressure
핵심 요약
Film blocking is caused by surface tackiness and high-temperature winding; antiblock agent and full cooling are effective countermeasures
