LDPE Film Lamination Delamination
문제 현상
The interlayer peel strength of the laminated film is low, with delamination and blistering.
원인 분석
Insufficient corona treatment or uneven adhesive coating; film surface contamination and moisture also affect lamination fastness.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
해결 방법
①Ensure corona treatment effect; ②optimize adhesive coating; ③control ambient humidity; ④do peel strength sampling inspection.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Lamination quality is a combination of surface treatment and coating process; peel test is the verification standard.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
