PE stretch film

Materials are widely used. The improvement of people's living standards, the country's industrial construction and national defense construction are inseparable from materials. In particular, the rapid development of polymer materials is mainly due to their wide molecular weight distribution, light weight, low density, excellent mechanical properties, insulation properties and other characteristics and changeable structures. However, a large number of surface and interface problems, especially the surface wettability problem, limit its application in some aspects. In order to meet the needs of the society for materials, it is necessary to modify the wettability of the surface of the polymer. Polyethylene is a thermoplastic resin made by ethylene polymerization, referred to as PE. Polyethylene is a crystalline high polymer, which is widely used in various fields such as hygiene products, packaging, daily necessities, and electrical appliances due to its advantages such as light weight, low price, non-toxic, odorless, corrosion resistance, and low dielectric constant. However, polyolefins (PP, PE, PS, PVC, PTFE, PMMA) are non-polar polymers, and surface and interface problems make them non-wetting, poor dyeability, abrasion resistance and printability, which hinder the development of such materials. promote.
