PBAT lamination strength
문제 현상
Insufficient lamination strength between PBAT film and other materials, interlayer peeling.
원인 분석
PBV compatibility with the lamination layer; lamination process; adhesive selection; surface treatment; heat seal temperature.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Compatibility evaluation; ②adhesive matching; ③surface treatment; ④lamination process optimization.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
Interlayer bonding of PBV lamination is structural performance; compatibility and process are equally important; testing verifies strength.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
