The characteristics, applications, and typical thicknesses of PET release films

The characteristics, applications, and typical thickness of PET release film In modern industrial fields, polyethylene terephthalate (PET) release film is a widely used thin film material. It is favored for its excellent performance and diverse applications. The following is a detailed introduction to the characteristics and applications of PET release films: The characteristics of PET release films are high temperature resistance. PET release films have good heat resistance and can maintain stability at high temperatures without deformation or release of harmful substances. Chemical corrosion resistance: This film is usually able to resist the erosion of most common solvents and chemicals, and is suitable for environments that require moisture-proof and anti-corrosion. High mechanical strength: PET film has high tensile strength and tear resistance, making it very sturdy and durable in various industrial applications. Good transparency: PET film has good transparency, which can achieve clear and transparent packaging effects. Good barrier properties: It can effectively prevent the penetration of oxygen and water vapor, and has a positive impact on the shelf life of food and other products. Easy to process: PET film is easy to print, cut, and die cut, suitable for various processing techniques. Environmental protection: PET materials can be recycled and reused, in line with the concept of sustainable development. The purpose of PET release film in the electronics industry: to protect sensitive components from dust, moisture, and scratches; It is also commonly used as a substrate for tape, such as double-sided tape. Medical equipment: used as packaging material for medical equipment, ensuring a sterile environment and providing physical protection. Label and label production: Due to its excellent printing adaptability and durability, it is widely used in various label production. Building materials: As one of the materials used for waterproofing or sound insulation, it enhances the thermal insulation performance of building exterior walls. Automotive manufacturing: used in the fields of interior protection or automotive film application. Food packaging: The barrier performance of PET release film helps to extend the shelf life of food while maintaining the freshness and quality of the product. The typical thickness of PET release film can be adjusted according to different needs, ranging from a few micrometers to several hundred micrometers. The following are some common thickness ranges: ultra-thin (less than 0.08 millimeters): mainly used for the protection of fine components in electronic products. Standard type (0.08 to 0.12 mm): suitable for general industrial purposes such as label backing and tape. Thick and heavy (greater than 0.12 millimeters): used in situations that require higher strength, such as protective covers in certain special environments. PET release film has become a key material in many industries due to its unique characteristics and wide applicability. With the development of technology and the continuous emergence of new demands, it is believed that more innovative PET films will be introduced in the future to meet the specific needs of different fields.
