LLDPE film raw material storage
문제 현상
Film bubbles increase after the raw material gets damp in the rainy season.
원인 분석
Although LLDPE pellets have low moisture absorption, the surface still adsorbs moisture; improper storage in the high-humidity rainy season environment makes the moisture content exceed the standard.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
해결 방법
①Store in sealed packaging; ②dry before use in the rainy season; ③control warehouse humidity; ④first in, first out.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
핵심 요약
Low moisture absorption does not mean management-free; moisture-proof measures in the rainy season cannot be omitted.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future.
