Polyester film - Introduction
Polyester Film is a transparent plastic film made of polyethylene terephthalate (polyethylene terephthalate). The following is a description of the nature, use, method and safety information of Polyester Film:
Nature:
1. Polyester Film has excellent physical properties, such as high strength, wear resistance, tensile resistance, tear resistance and temperature resistance.
2. It has good transparency, optical properties and electrical insulation properties.
3. Polyester Film has good chemical stability and can resist the corrosion of most common chemicals.
4. It has a low water vapor transmission rate, so it can be used to package food and pharmaceutical products to a certain extent.
Use:
1. packaging industry: Polyester Film is widely used in food, medicine, cosmetics, electronic products and other fields of packaging.
2. Printing industry: Polyester Film can be used to print labels, stickers, business cards, etc.
3. Electronics industry: Polyester Film can be used to make electronic displays, solar panels and other electronic products.
4. construction industry: Polyester Film can be used in glass, walls and curtains and other fields.
Preparation Method:
The preparation of Polyester Film is usually carried out by the extrusion method of polyester plastic. In the manufacturing process, the polyethylene terephthalate particles are melted and extruded, and after cooling, a continuous film is formed.
Safety Information:
1. Polyester Film is relatively safe under normal conditions and will not produce harmful gases or substances. However, in the case of high temperature, Polyester Film may release harmful substances such as formaldehyde, so it is necessary to pay attention to ventilation and safety during heat treatment.
2. When using Polyester Film for food packaging, it is necessary to ensure that the film meets the corresponding food hygiene standards to ensure its safety.
3. Polyester Film itself has good chemical resistance, but in contact with certain chemicals, such as strong acid, strong alkali, etc., still need to pay attention to the corrosion of chemicals, it is recommended to use a larger thickness of the Polyester Film for protection.
