PE stretch film is mainly made by casting polyethylene particles and other plastic particles. This film has high transparency, tensile strength, tear resistance, and puncture resistance, and is therefore widely used in various fields.

The production process of PE stretch film usually includes steps such as raw material preparation, extrusion molding, etc. The raw materials mainly include polyethylene resin, fillers, and additives, among which resin is the main component of the stretch film, fillers can increase the strength and stability of the film, and additives include antioxidants, UV blockers, etc., which can effectively improve the performance of the film. During the extrusion molding process, the raw material is heated to a molten state and then extruded through a mold plate. This process requires controlling parameters such as temperature, extrusion speed, and pressure to ensure the quality of the film.

Overall, PE stretch film plays an important role in packaging, logistics, and warehousing due to its excellent performance and wide range of applications.
