LLDPE Film Opening Blocking
Sorun Belirtisi
Film rolls block and are difficult to open.
Neden Analizi
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.
Çözüm
① Add antiblock agent/slip agent; ② reduce winding tension; ③ fully cool; ④ control storage temperature.
Temel Çıkarım
Blocking = additives + tension + temperature.
