1. Choose the right glue
Select the appropriate glue for aluminized film composites such as VMCPP and VMPET. The difference between VMCPP and VMPET is different.
(1) Oven and composite roll temperature are reduced by 5-10 ° C;
(2) Curing chamber temperature does not exceed 45 ° C;
(3) PET/VMPET/PE (CPP) is compounded and cured for 1-2 hours after the first pass;
(4) If the air is dry, reduce the curing dose by 10%.
