Six requirements for the use of PE protective plastic bags

At present, it is mainly used for postal packaging of products. The bubble bag is equipped with a shock-absorbing bubble film. There are countless small bubbles in the bubble film, so it is light in weight, elastic, and has the functions of sound insulation, shock resistance, and scratch resistance. It is widely used in electronics, instruments, ceramics, handicrafts, and household appliances. Shock-resistant cushioning and protective packaging for bicycle shops, kitchens, furniture, hardware tools, glass products and precision instruments. It can prevent the objects from being squeezed, vibrated and rubbed during the transfer process, and has a certain protective effect on the objects that are afraid of being squeezed. In addition, various special bubble bags such as anti-static can also be manufactured by adding different additives to the raw materials. Anti-static air-cushion bags are used for packaging electronic components and components, such as integrated circuit boards, cards, etc. The use requirements of PE protective film are mainly in the following points 1. Good weather resistance: under the condition of sunlight exposure, the service life can be as long as half a year to one year; 2. The peeling force is stable: the change over time is small, that is, the smaller the increase in the peeling force is The better; 3. Appropriate viscosity: easy to stick and tear; 4. Long storage period: stored in the warehouse for more than one year, with no change in quality; 5. Excellent mechanical properties: Tensile strength, elastic modulus, elongation that meet user requirements length etc. 6. No pollution and no corrosion: the adhesive is inert and will not chemically react with the surface of the material to be adhered;
