Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of PE film, specifically to a winding device for PE film processing. BACKGROUND

[0002] ‌PE film, namely polyethylene film, is a film-shaped material processed from polyethylene, a high molecular polymer.

[0003] PE film has moisture resistance and low moisture permeability, and is one of the most widely used high molecular materials in the world today. It can be divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. PE films with different densities have different properties, for example: low-density polyethylene film has good transparency and heat sealing property, can prevent water and moisture, but has low tensile strength and large tensile elongation, and is prone to wrinkling. High-density polyethylene film has better heat resistance and mechanical strength than low-density polyethylene film, and has small tensile elongation.

[0004] Low-density polyethylene, also known as high-pressure polyethylene (LDPE), is the lightest variety of polyethylene resin, which is a waxy particle with milky white color, no odor, no smell, no toxicity, and no luster on the surface. It has good flexibility, ductility, electrical insulation, transparency, easy processability and certain air permeability. It has good chemical stability, resistance to alkali and general organic solvents.

[0005] Linear low-density polyethylene (LLDPE) is a basically linear polymer (polyethylene) with a large number of short branches, usually produced by copolymerization of ethylene and long-chain olefins. Linear low-density polyethylene is different from traditional low-density polyethylene (LDPE) in structure, because it does not have long-chain branching. The linearity of LLDPE comes from the different manufacturing processes of LLDPE and LDPE. Generally, LLDPE is produced by copolymerization of ethylene and higher alpha-olefins such as butene, hexene or octene at lower temperature and pressure. The molecular weight distribution of LLDPE polymer produced by copolymerization process is narrower than that of conventional LDPE, and combined with linear structure, it has significantly different rheological properties.
