In daily life, composite packaging bags can be seen everywhere. In supermarkets, the packaging bags used to hold snacks, candy and biscuits are all packed with composite bags. Many food manufacturers often see the bags separated into layers when using composite bags. Today, Qiji packaging manufacturers will analyze why these bags are separated.
1: Delamination caused by composite bag material failure
Many manufacturers think that the materials of all bags are the same, but this is not the case. For different characteristics of products, the materials of packaging bags are different. Some products have large oil content, some products need high temperature treatment, and some products need low temperature refrigeration. Therefore, the separation caused by incorrect selection of bag materials is very common.
2: Layer separation caused by unqualified composite technology of composite bag
Composite plastic bag is a kind of packaging bag made of more than two layers of materials, which is called "composite bag". These materials are all bonded together through special processes. If the technology is not up to standard, more or less glue will affect the separation of bags in the future.
3: The curing time of composite bag is not enough
After the composite bag is compounded, the composite material needs to be baked in an environment with a constant temperature of 50 ° C for 48 hours. The purpose of baking is to dry the glue in the process of compounding. In order to reduce the production time, some manufacturers take out the bags before the baking time. Such bags will be separated after a period of time.
