Classification

PET Resin：It is the raw material in granular form, which can be processed into different products through various molding processes. It is divided into general - purpose and engineering - grade types according to performance.

PET Film：Made by stretching the PET resin film - like. It includes plain film, release film, and coated film, which are used in different fields such as packaging, electronics, and optics.

PET Bottle：A common form of PET products, mainly used for packaging beverages, edible oils, and other liquids. It can be divided into carbonated beverage bottles, mineral water bottles, etc. according to the types of packaged substances.

Advantages

Excellent Physical Properties：It has high strength, stiffness, and hardness, with good impact resistance and wear resistance.

Good Chemical Resistance：Resistant to most acids, alkalis, and organic solvents, which ensures the stability of the material in different chemical environments.

High Transparency：The transparency of PET is very high, which can reach more than 90%, so it has a good visual effect.

Good Barrier Properties：It has low gas and water vapor permeability, which can effectively prevent the entry of external gases and water vapor and protect the packaged products.

Recyclable：PET is a recyclable material, which is beneficial to environmental protection.

Applications

Packaging Industry：Widely used in packaging bottles, packaging films, and trays. Such as beverage bottles, food packaging films, and fruit and vegetable trays.

Textile Industry：Used to make polyester fibers, which are the main raw materials for clothing, home textiles, and industrial textiles.

Electronics Industry：Applied in insulating materials, flexible printed circuit boards, and LCD substrates due to its excellent electrical insulation and dimensional stability.

Medical Field：Used to make medical packaging, such as medicine bottles and blister packaging. In addition, PET - based materials are also used in some medical devices.
