LLDPE Stretch Film Insufficient Self-Adhesion
문제 현상
Layers of stretch wrap film do not stick, and pallet wrapping is loose.
원인 분석
LLDPE stretch film relies on special tack (the grade itself or the tackifier PIB); insufficient tackifier or the wrong grade results in no stickiness.
해결 방법
① Select special stretch film grades; ② evaluate PIB tackifier addition; ③ control film thickness and storage aging; ④ perform tack verification in low-temperature environments.
핵심 요약
Stretch film tack = grade + tackifying system.
