Description

Technical Field

[0002] The production of PE film mainly involves the use of PE particles through a specific process to make a film. PE film, also known as polyethylene film, is a film material produced from PE particles. This material is moisture-resistant and has low water permeability. The production process of PE film uses PE particles as raw materials. These particles are the solid form of polyethylene and have good plasticity and processability. The PE particles are heated to a molten state. This step is completed by a heating device, which makes the particles become liquid, facilitating the formation of a film. The molten PE is squeezed out through an extruder to form the initial form of the film. This step is a key step in film forming. The extruded film is quickly cooled by a cooling device to solidify the formed PE film. The cooled PE film is rolled into a roll for storage and subsequent use.
