Polyethylene film,high density,industrial film - Introduction
High-density polyethylene film (HDPE) is a film made of polyethylene material with high density and high strength. It has the following properties:
1. High density: HDPE film has a high molecular density, so it is harder and tougher than low-density polyethylene film.
2. Chemical resistance: HDPE film has good corrosion resistance to many chemical substances and is usually used for packaging chemicals and corrosive substances.
3. High tensile strength: due to the high density, HDPE film has high tensile strength, which is suitable for stress environment such as heavy load and tear resistance.
4. Sealing: because of its high degree of polymerization, HDPE film has good sealing performance and is often used to make sealing bags and packaging materials.
High-density polyethylene film is widely used in the following fields:
1. Packaging materials: HDPE film is commonly used in food packaging, pharmaceutical packaging and chemical packaging and other fields.
2. Agriculture: it can be used as greenhouse covering material, agricultural film, planting bags and other agricultural purposes.
3. Construction and building materials: HDPE film can be used as waterproof material, plastic film, etc.
4. Industrial applications: It is also commonly used in the production of garbage bags, transport bags and plastic containers.
The preparation method of high-density polyethylene film generally adopts an extrusion process, that is, by heating the high-density polyethylene material to a molten state, and extruding the molten polyethylene into a film through a die or extruder.
Note the following safety information when using and handling HDPE film:
1. Avoid high temperature: HDPE film is easy to melt and avoid contact with high temperature items.
2. Avoid chemical corrosive substances: try to avoid HDPE contact with strong acid, strong alkali and other chemicals.
3. Safe disposal: When discarding or disposing of HDPE film, garbage classification and disposal should be carried out in accordance with local environmental regulations.
4. Avoid placing in direct sunlight: Exposure to sunlight for a long time, HDPE film may age and discolor.
