Everyone in industrial production knows that films need to be used in industrial production. This is undoubtedly true, but many people do not know what films are used in industry. For example, PET polyester film, what does it do?  Simply put, PET polyester film is made of polyethylene terephthalate as raw material, made into thick sheets by extrusion, and then biaxially stretched. Made of film material.

PET polyester film is a colorless, transparent and shiny film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness and It has good fragrance retention and is one of the commonly used barrier composite film substrates. Now Guangdong Hangbang Co., Ltd. will introduce to you the product characteristics of PET polyester film.

1. Product features

The surface of the film is smooth and smooth, without wrinkles, tears, particles, bubbles, pinholes and other defects. This product has the advantages of excellent physical and mechanical properties, high temperature resistance, small thickness tolerance, high transparency, low thermal shrinkage, and good flexibility.

2. High shrinkage rate

The shrinkage rate of ordinary PVC film is generally around 55%, but the shrinkage rate of PET polyester film in a boiling water bath can reach up to more than 75%. Whether it is a thin tube, a cube, a cylinder, or even a diameter, the difference is very large. The bottles can be wrapped tightly and snugly.

3. Packaging and storage

The product packaging specifications are various, including carton packaging, pallet packaging, and can also be cut into tapes and rolls according to customer requirements. Store in a dry and clean warehouse below 45°C, and should not be near fire, heat sources or exposed to direct sunlight.

4. High transparency, no crystal points

Biaxially stretched and cast PET polyester film has extremely high transparency and gloss without crystal points.

5. Product usage

PET polyester film is now widely used in packaging, printing, screen printing, pad printing, nameplates, membrane switches, flexible circuits, insulation products, circuit boards, laser anti-counterfeiting, lamination, electronics, sealing materials, reflective films Materials, waterproof materials, adhesive products, die-cutting and punching processing and other industries. Can be cut into sheets according to customer requirements.

Guangdong Hangbang Co., Ltd. will share the product characteristics of PET polyester film here today. Now PET polyester film has passed the U.S. UL certification and can be widely used in motors, packaging, printing, clothing, and electronics. Users provide slitting and reeling and block tape services. It has excellent physical and chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields.
