PET, or polyester, is a generic term for polymers obtained by the condensation of polyols and polyacids. It mainly refers to polyethylene terephthalate (PET), and customarily includes polybutylene terephthalate (PBT) and polyarylenes, and other linear thermoplastic resins, and is a class of engineering plastics with excellent performance and a wide range of uses. In the cosmetic packaging market, PET materials are often used to make a wide variety of plastic cosmetic bottles and jars. This article will discuss the benefits of using PET material as a raw material for cosmetic jars.

State of the art of PET materials
Due to the rapid crystallization of PET melt when cooling, molding processing is more difficult, the mold temperature must be maintained above 140 ℃ to obtain a good performance of the product, otherwise, the product is brittle. Therefore, for a long time, people did not use PET as a thermoplastic engineering plastic. With the development of science and technology, these molding and processing difficulties have been overcome through the use of new condensation catalytic systems or co-condensation processes, reinforcement with glass fibers, or control of the crystalline structure and production of high molecular weight polyesters, etc. PET is increasingly used in the manufacture of beverage bottles and glass fiber reinforced plastics.
Advantages of using PET material
The advantage of polyester bottles is lightweight, it is only 1/9 to 1/15 of the weight of a glass bottle. in addition, the polyester bottle has high mechanical strength, are not easy to break, is easy to carry and use, and has good transparency, glossy surface, are non-toxic, good airtightness, good freshness, less energy consumption for producing polyester bottle, the waste bottle can be regenerated and used. It has an important position in the cosmetic packaging industry. The use of PET material as the raw material for cosmetic jars has roughly the following advantages.
l PET material is highly transparent and glossy, producing cosmetic jars with high transparency and a flat, glossy surface.
l PET softening temperature and melting point are high, 248 ℃ and 276 ℃ respectively, good heat resistance, compared to other plastic materials, PET material can avoid high temperature burns cosmetic jars, so as to avoid affecting the quality of cosmetics in the cosmetic jars.
l PET material recycling technology is gradually developing, and in the future, PET material recycling will be simpler and more systematic, which means that PET material will cause less damage to the environment.
l PET has good resistance to low temperature, the minimum temperature is -100℃, even in the cold Russian Siberia, you don't have to worry about the cold and brittle skin in winter.
In addition to the above-mentioned advantages of PET material, using PET as the raw material for cosmetic jars not only produces cosmetic jars with good sealing properties but is also resistant to abrasion and is durable. In other words, PET plastic jars can make the appearance of glass jars, but at the same time have the advantages of being unbreakable, safe, environmentally friendly, and easy to transport.
