Abstract

The invention discloses an easy-to-tear protective film special for a household appliance panel, relates to the field of protective films and aims to solve the problems that the existing protective film is prone to warpage, edge wavy lines, irregular cracks and the like after being torn, thus affecting the working efficiency and the aesthetic appearance of products. The easy-to-tear protective film comprises an inner layer, a middle layer and an outer layer, wherein the raw materials of the inner layer comprise the following parts by weight: 80-120 parts of LDPE and 1-2 parts of a highly dispersed silicon opening agent. The raw materials of the outer layer comprise the following parts by weight: 15-35 parts of the LDPE and 1-2 parts of the highly dispersed silicon opening agent. The raw materials of the middle layer comprise the following parts by weight: 50-80 parts of the LDPE, 12-25 parts of LLDPE and 10-20 parts of polyolefin modified particles. The easy-to-tear protective film cancarry out direct tearing without warping or slanting tear openings, thus improving the surface appearance quality of the products and improving the production working efficiency.

Description

technical field [0001] The invention relates to the field of protective films, more specifically, it relates to a special easy-to-tear protective film for home appliance panels. Background technique [0002] With the development of science and technology, electronic appliances have gradually entered people's lives. Since electronic appliances are generally more expensive, their surfaces are easily scratched during the production and handling of electronic appliances, and manufacturers usually A layer of appliance board protective film is attached to the surface. [0003] The home appliance board protective film can be attached to the surface of metal, glass, plastic, etc. of home appliances, so that home appliances can be protected during manufacturing, transportation, secondary processing, storage and use, and prevent the surface of home appliances from being polluted, scratched and slowed down. The surface of the product is oxidized, thereby improving the appearance quali...
