Bubble bags are mainly made of high-pressure polyethylene bubble film through film cutting. The bubble film is cut into the required size, and then the bag is made by a special bag-making machine for bubble film (hot-drying and hot-cutting bag-making machine), which is mainly used for logistics transportation protection of electronic products, plastic products, metal products, ceramic products, glass products and other products that need buffer protection. Bubble film is made of high-pressure low-density polyethylene, which is a transparent flexible packaging material widely used at present.

Its principle is that air is contained in the film to make it form bubbles to prevent product collision, to ensure that the product plays a protective role in vibration, and also has the function of heat preservation and heat insulation, which is suitable for packaging or turnover of different products in all walks of life! Because the middle layer of the air cushion film is filled with air, it is light, elastic, sound-proof, shock-proof and wear-resistant. It is waterproof, moistureproof and compressive. Bubble bags are divided into single and double sides. Single-sided bubble bag is suitable for anti-static bubble roll to protect its lighter products, and double-sided bubble bag is suitable for packaging larger and heavier items. Single-sided and double-sided bubble bags are suitable for packaging products in various industries, such as bag making and slicing. Single-sided and double-sided bubble bags can be equipped with anti-static bubble bags, and there are different colors and prints. They can also be combined with other materials to increase protection and beauty. Mainly used for postal packaging of products. The bubble bag is attached with a bubble film to reduce the vibration of the double-sided bubble bag. There are countless small bubbles in the bubble film, so it is light and elastic, and has the functions of sound insulation, shock prevention and scratch prevention. Widely used in shock absorption and protective packaging of electronics, instruments, ceramics, handicrafts, household appliances, automobile shops, kitchens, furniture, hardware tools, glass products and precision instruments. It can prevent objects from being squeezed, shaken and rubbed in the process of transmission, and has a certain protective effect on objects that are afraid of being squeezed and pressed. In addition, by adding different additives to the raw materials, various special bubble bags such as antistatic can be made. Anti-static air cushion bag is used to package electronic components, such as integrated circuit boards and cards. It can not only prevent static electricity, but also play the role of buffering and shock prevention.
