What does compounding in paper-plastic compound bags mean?

Our life is inseparable from the use of packaging bags. There is a product called paper-plastic composite bag in the packaging bag. Many people do not know what composite means. In order to have a deeper understanding of this problem, we must first remove the material of the paper-plastic composite bag. Similar to the paper-plastic composite bag, it is generally processed by two or more materials. This processing is a composite process. Therefore, the paper-plastic composite bag uses a paper-plastic composite material, and then it can be made into a packaging bag. The printability of the paper-plastic composite bag is very good, and it is also relatively heat-resistant. In the middle layer of the paper-plastic composite bag, the treatment of shading and fragrance preservation can be carried out, which is equivalent to having a better barrier property. The inner layer of the paper-plastic composite bag is generally made of non-toxic, oil-resistant and waterproof materials.
Paper-plastic composite bags are widely used, for example, they can also be used in vacuum packaging. I believe that with the improvement of our living standards, paper-plastic composite bags will play a greater role.
