Have you used composite bags? Why is there a delamination?

    In ordinary life, composite bags can be seen everywhere in supermarkets. The packaging bags used for snacks, candies, and biscuits are all packaged in composite bags. Many food manufacturers often have the reason of bag separation when using composite bags. , Today we will help you analyze why these bags will be separated from the layer.

 

    One: Layer separation caused by improper materials Many manufacturers think that the materials of all bags are the same, but this is not the case. The materials of the packaging bags are different for different characteristics of the products. Some products have high oil content, and some products require For high-temperature treatment, some products require low-temperature refrigeration, so delamination caused by incorrect selection of the material of the bag is very common.

 

    Two: The separated composite bag caused by the failure of the composite technology is a packaging bag made by combining materials of more than two layers, which we professionally call: composite bag. These materials are bonded together through a special process. If the technology is not good enough, the amount of glue used in the compounding process will affect the separation of the bag in the future.

 

    Three: Not enough maturation time after compounding
    After the compound bag is compounded, the compounded material needs to be baked in an environment with a constant temperature of 50 degrees. The baking time must reach 48 hours. The purpose of baking is to dry the glue in the compounding process. In order to reduce the production time, some manufacturers take them out to make bags before they are baked. Such bags will surely appear to be separated after a period of time. The several reasons mentioned above are the main reasons for the delamination of the composite bag. Therefore, when choosing a composite bag manufacturer, you must investigate and understand clearly, Only in this way can the product be affected by the layer separation that occurs during the use of the product.
