LDPE vs PP Selection
문제 현상
Microwave lunch box lids made of LDPE deform
원인 분석
LDPE has a low heat resistance temperature and softens in the microwave environment; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
해결 방법
Select PP for heat-resistant occasions; LDPE is limited to low-temperature flexible applications; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate the effective measure
핵심 요약
Select PP for heat-resistant applications, and LDPE according to the temperature boundary; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
