LLDPE Film Opening Blocking
Fenómeno do problema
Film rolls block and are difficult to open.
Análise das causas
LLDPE film surface tack is relatively large, and blocking occurs when slip and antiblock agents are insufficient; large winding tension and high film temperature aggravate it.
Solução
① Add antiblock agent/slip agent; ② reduce winding tension; ③ fully cool; ④ control storage temperature.
Conclusão principal
Blocking = additives + tension + temperature.
