The specific structure depends on the requirements of the packaging. Since the printing layer and the reinforcement layer are usually biaxially stretched films, the strength of the composite material is relatively high, and it is not easy to be torn and punctured. When consumers use composite packaging bags containing beverages, the beverages are likely to spill when they are torn, which brings great inconvenience to consumers. At present, there is a packaging form with a socket on the market. It is welded to the inner layer of the pre-punched composite material with a piece of easy-to-puncture sealing material, which has t...
