LDPE Film Wrinkling
Fenómeno do problema
LDPE film wrinkles during winding
Análise das causas
Uneven thickness causes uneven winding tension distribution, and the thin areas wrinkle; 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
Solução
Solve thickness uniformity first; optimize winding tension; adjust the spreader roller; 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
Conclusão principal
The root cause of wrinkling lies in thickness uniformity; 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
