POE film self-adhesion too strong
Problem Phenomenon
POE film self-adhesion separation force >5N/cm, wound roll cannot be unwound
Cause Analysis
POE high octene, surface soft and adhesive; winding >50°C
Solution
1) Winding <30°C, full cooling; 2) Erucamide 0.2-0.5wt% antiblocking agent; 3) Reduce octene to reduce tackiness
Key Takeaway
POE film self-adhesion is caused by surface softening and low molecular migration; antiblocking agent and cooling are effective
