Bubble bags are primarily made by cutting high-pressure polyethylene bubble film into required bag size, then processed through a bubble film bag-making machine (hot-dry-cutting bag-making machine) to produce the bags. They are mainly used for cushioning packaging of electronic products, plastic products, metal products, ceramic products, glass products, and other products requiring cushioning protection during logistics transportation. The bubble film is made from high-pressure low-density polyethylene and is a widely used transparent soft packaging material with various applications.
