LLDPE film slip agent migration
문제 현상
The slip effect changes over time; the friction coefficient is unstable.
원인 분석
Slip agent migration to the surface takes time; temperature and thickness affect the migration rate, and excessive slip agent also blooms out affecting heat sealing and printing.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
해결 방법
①Control the slip agent addition amount; ②specify testing time points; ③balance slip and heat seal requirements; ④select the slip system by application.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
핵심 요약
Slip agent management is a time-dependent subject; standardization of dosage and testing timing is critical.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
