The bubble bag is mainly made of high-pressure polyethylene bubble film through film cutting process, the bubble film is cut to the size required for bag making, and then the bag is made by a bubble film special bag making machine (hot baking hot cutting bag making machine). Bubble bags are mainly used for logistics and transportation protection of electronic product buffer packaging, 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. It is a transparent flexible packaging material currently widely used and has a wide range of applications.
The principle is that the film contains air to form air bubbles to prevent the product from impacting, ensuring that the product plays a protective role when it is shaken, and also has the function of heat insulation. It is suitable for different product packaging or turnover in various industries. Because the middle layer of the air cushion film is filled with air, it is light and elastic, and has the properties of sound insulation, shock resistance and wear resistance. It is waterproof, moisture-proof, and pressure-resistant.
There are two types of bubble bags: single-sided and double-sided. Single-sided bubble bags are suitable for protecting lighter products. Double-sided bubble bags have strong shock resistance and are suitable for larger and heavier items. Single and double-sided bubble bags are suitable for packaging of products in various industries such as bag making and slicing. Single and double-sided bubble bags can be equipped with anti-static bubble bags, as well as different colors and printing. It can also be compounded with other materials to increase protection and beauty.
According to different tissues, bubble bags are classified as: Kraft paper bubble bag, pearl film bubble bag, aluminized platinum bubble bag, transparent bubble bag (there are two layers and three layers).
According to different materials, bubble bags are classified as: Ordinary bubble bag, anti-static bubble bag, static conductive bubble bag.
According to the structure, bubble bags are classified as: Bare airbag, kraft paper airbag, other material airbag.
Bubble mailers are mainly used for postal packaging of products. Shock-absorbing bubble film is included in the bubble bag. There are countless small bubbles in the bubble film, so it is light and flexible, and has the functions of sound insulation, shock resistance, and scratch resistance. It is widely used in shock-resistant cushioning, protective packaging in electronics, meters, ceramics, crafts, household appliances, auto dealers, kitchens, furniture, hardware tools, glass products and precision instruments. It can prevent the objects from being squeezed, shaken, and rubbed during the transfer process, and has a certain protective effect on items that are afraid of being squeezed and pressed. In addition, by adding different additives to the raw materials, various special bubble bags such as anti-static can also be manufactured. Anti-static air cushion bag is used to pack electronic components and components, such as integrated circuit boards, cards, etc., which can prevent static electricity and also play a role of buffering and shockproof.
