BOPET (biaxially oriented polyethylene terephthalate) is an outstanding polymer material with superior properties such as high strength, heat resistance, barrier properties, transparency, and processability. It is widely used in various fields due to these advantages.
Packaging field: BOPET film is a key material for packaging in fields such as food, medicine, and daily chemicals. It is often used as the outer layer of steaming packaging bags and can withstand a temperature range of -70℃to 150℃. It has excellent water-blocking, gas-blocking, and aroma-preserving properties, which can extend the shelf life of products.
Electrical and Electronic Insulation: Its excellent electrical insulation properties and heat resistance make it suitable for insulation films for wires and cables, insulation films for touch switches, magnetic recording tape bases (such as audio and video tapes), and special films for capacitors, among other electronic components.
Optics and Display Technology: BOPET films can be processed through processes such as aluminizing and coating to produce functional optical films such as reflective films, brightening films, diffusion films, and conductive films, which are widely used in liquid crystal display panels, solar cell back sheets, automotive window films, and building glass window films, etc.
Printing and Decoration: After corona treatment, the surface tension of BOPET film is high, which is suitable for printing and laminating processes. It is used for manufacturing protective card films, drawing films, laser holographic anti-counterfeiting labels (such as ID cards, credit cards), as well as decorative materials like gold and silver threads.
Industrial and Safety Applications: This includes reflective films (used for traffic signs, reflective police uniforms), heat shrink films, twisted film, high-temperature resistant tapes, etc., meeting the needs of industrial safety and energy conservation and environmental protection.
