PA66 barrier film
문제 현상
PA66 packaging film oxygen barrier decreases in rainy season
원인 분석
PA66 oxygen barrier decreases with rising humidity, and barrier performance deteriorates in high-humidity environments; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
해결 방법
Use PA66 and polyolefin multilayer composite structures for high-humidity applications; test oxygen transmission rate according to actual humidity conditions; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
핵심 요약
PA66 oxygen barrier is affected by humidity, high-humidity scenarios require composite structures; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
