Classification Of The Use Of Polyester Film
Polyester Film (PET) is a thin film material which is made of polyethylene terephthalate as raw material by extruding method, and then by biaxial stretching. Polyester Film environmental protection film Pet film white film and other printing and packaging supplies, widely used in FRP industry, building materials industry, printing industry, medical and health. Polyester film is also called polyester Film optical film paper polyester film film membrane film of benzene tin films.
According to the use of polyester film classification: Because the characteristics of polyester film determines its different uses. Different applications of polyester film on the requirements of raw materials and additives and processing technology have different requirements, its thickness and technical indicators are not the same; In addition, only bopet have a variety of uses, so according to the use of the film is boPET. Can be divided into the following categories:
1, electrical insulating film. Because of its good electrical, mechanical, heat and chemical inertia, good insulation performance, high breakdown voltage, especially for electronic and electrical insulating materials, commonly used standard thickness are: 25, 36, 40, 48, 50, 70, 75, 800, 100 and 125 (microns). These include wire and cable insulating membranes (thickness of 25-75) and touch-switch insulating membranes (50-75).Polyester Film
2. Capacitance film. It has many advantages such as high tensile strength, high dielectric constant, low loss factor, good thickness uniformity, good electrical property and large electric resistance, and is widely used in capacitor dielectric and insulating interlayer. Commonly used standard thickness of 3. Summ, 3. Im, 4, 4.3, 4. Im, Summ, 6 6, Im, Mus, 9. Im, 10, 12.
3, protect card film. With good transparency, high stiffness, heat stability, good surface smoothness of the performance, uniform longitudinal and horizontal tensile properties, and has waterproof, oil and chemical protection and other excellent performance. Dedicated to the protection of pictures, documents, documents and office supplies packaging, so that the film as a protective coating after the smooth and beautiful, can maintain the original clarity and deformation. Common standard thickness is ten. 75, 12, 15, 25, 28, 30, 36, 45, 55, 65, 70, of which 15 above mainly as a laser anti-counterfeiting film or high-end protective card film used.Polyester Film
4, Nano Pet film: High Transparency and gloss: nanoparticles particle size between 1 100n, less than the wavelength of visible light, the transparency of the film less.
High barrier performance and heat resistance: using nano-materials with special properties and unique processing technology, nano-scale materials are evenly dispersed pet matrix, in the film production process by stretching orientation, so that the pet film presents excellent barrier performance, O, CO2, $literal through the rate of doubling down, heat-resistant performance also greatly improved, can expand the application of pet, greatly prolong the shelf life of the packaging, can also be used for hot filling or sterilization occasions.Polyester Film
