LLDPE film downgauging for cost reduction
Fenómeno del problema
Hope to reduce thickness to cut cost but worry about insufficient strength.
Análisis de la causa
LLDPE's high strength allows film downgauging; but after downgauging the processing window narrows, and the difficulty of film breakage and thickness control rises.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solución
①Use LLDPE's high strength to implement downgauging; ②combine with PPA to improve processing; ③strengthen thickness measurement and bubble stabilization; ④stepwise downgauging verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Conclusión clave
Downgauging is LLDPE's main value point; only with process assurance in place can cost be reduced without reducing quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
