LLDPE film shrink packaging application
Sorun Belirtisi
Shrink packaging film shrink force and shrinkage rate do not meet standards.
Neden Analizi
Shrink performance is determined by the degree of frozen orientation; the LLDPE formulation and stretching cooling process need dedicated design.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Çözüm
①Optimize the stretching and cooling process; ②select a shrink-film-dedicated grade; ③test the shrink curve; ④match packaging machine parameters.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
Shrink film is a dedicated product of formulation-process synergy; shrink curve testing is a development verification means.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
