What is BOPET film used for?
BOPET is widely used in daily life - packaging and printing account for 65%, and electronic/electrical appliances and industrial use account for 35%.
1. Food, clothes, cosmetics, and other products packaging - such as ordinary packaging film, bronzing film, and transfer film;
2. Car window film, and mobile phone film which all belong to the optical film classification in BOPET.
3. Release type protective film, diffusion film, incremental film, etc.
4. BOPET can also be used in solar panels, such as solar backing film,
5. Other industrial films such as insulating film, motor film, etc.
What are BOPET film's trends and profits?
The profit of the BOPET market is quite considerable. In the past year or two, the price of BOPET has fluctuated frequently. At present, the biggest factor affecting the price change of BOPET film is the raw material. Every change in the BOPET film price is inseparable from the boost of the raw material.
What are the advantages of BOPET film?
BOPET is a high-grade film produced by drying, melting, extrusion, and biaxial stretching of polyester chips. It has excellent properties such as high mechanical strength, good optical properties, good electrical insulation properties, wide operating temperature, and strong chemical corrosion resistance.
How does BOPET film perform?
BOPET film is a biaxially oriented polyester film. BOPET film has the characteristics of high strength, good rigidity, high transparency, and high gloss. It is odorless, tasteless, colorless, non-toxic, and has outstanding toughness.
First, high-speed printing and lamination can be carried out. Due to BOPET film's high transparency and good printing effect, it is unmatched by any general-purpose plastic film. Second, BOPET film has good tear resistance and is resistant to the surrounding environment. Insensitive to changes, in the range of 70-220 °C, the film has good firmness and toughness and is widely used in hot stamping base film and vacuum aluminized base film; third, BOPET film has low permeability to odor and gas, the permeability to water vapor is also low, and it also has high transparency and gloss. In other words, the disadvantage of BOPET film is that the heat sealing performance is poor.
What are the main applications of BOPET film?
The downstream application industries of BOPET polyester film are mainly packaging materials, electronic information, electrical insulation, card protection, image film, hot stamping foil, solar energy applications, optics, aviation, construction, agriculture, and other production fields. At present, the largest application field of BOPET film produced by domestic manufacturers is the packaging industry, such as food and beverage packaging, and pharmaceutical packaging, and some special functional polyester films are used in high-end fields such as electronic components and electrical insulation.
