The temperature of the curing chamber must be able to reach 45~60℃ in a short time.
The maturation of ordinary composite bags generally requires more than 48 hours of heat preservation at 50°C; retort bags, aluminum foil, aluminized film, and 3-layer or more composite bags generally require more than 70 hours of maturation at 60°C.
When the composite film is put into the curing room, the product name, quantity, specification, and time of entering the curing room should be marked, so that it is not easy to be confused and the curing effect is guaranteed.
During bag making, if the curing effect is found to be unsatisfactory, the temperature of the curing chamber can be adjusted or the curing period can be extended, and the amount of adhesive applied during compounding can also be adjusted to meet the required requirements.
