Discussion on the manufacturing process of high-temperature cooking bag

High-temperature cooking bag is a composite plastic film bag that can be heated. It has the advantages of both can container and boiling water resistant plastic bag. Let's introduce the manufacturing process of high-temperature cooking bags to you.

The ink and glue used in the high-temperature cooking bag are generally made of polyurethane resin. The better the moisture and heat resistance of the polyurethane resin, the better the adhesion and high temperature resistance of the cooking bag. If the ink or glue of the cooking bag undergoes hydrolysis reaction after heating, the viscosity of the cooking bag will be reduced. In order to solve this problem, curing agent is needed to improve the adhesive strength of the cooking bag.

If you want to give full play to the main solid reaction of the cooking gum and ensure the composite quality, you need to carry out a 40-55, 3-5 day ripening period. In the process of bag making, the adaptability evaluation of roll film should be fully done to ensure smooth film moving, good heat sealing and stable bag making quality during each production.
