CEF film blocking and difficult delamination
Fenómeno do problema
The interlayer blocking force of the CEF film is >5N/15mm, and the automatic slitting machine cannot delaminate
Análise das causas
The CEF surface has strong adhesion; the film temperature is too high >40°C during winding; low-molecular substances migrate to the surface to form an adhesive layer
Solução
1) Add 0.3-0.5wt% anti-blocking agent erucamide; 2) Fully cool to <25°C before winding; 3) Add 0.2wt% slip agent to synergistically reduce blocking; 4) Reduce the winding tension to reduce the interlayer pressure
Conclusão principal
Film blocking is caused by surface tackiness and high-temperature winding; anti-blocking agent and sufficient cooling are effective countermeasures
