LDPE Film Lamination Delamination
Fenómeno do problema
The interlayer peel strength of the laminated film is low, with delamination and blistering.
Análise das causas
Insufficient corona treatment or uneven adhesive coating; film surface contamination and moisture also affect lamination fastness.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience
Solução
①Ensure corona treatment effect; ②optimize adhesive coating; ③control ambient humidity; ④do peel strength sampling inspection.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
Lamination quality is a combination of surface treatment and coating process; peel test is the verification standard.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
