What is PET plastic? 

PET, PETE, PETP, or PET-P is a thermoplastic that belongs to the Virgin plastics,  and is used in fiber synthesis, beverage, food, and liquid containers, extrudable sprayed for shaping, and in the industry is frequently combined with glass fibers.

Characteristics of PET Plastic:

• PET is a thermoplastic that softens into a liquid when heated and then solidifies when cooled. There are over 40 different types of thermoplastics; PET belongs to the engineering plastic line in the popular thermoplastic line. PET-like plastics include polyoxymethylene (POM), poly acetate, polycarbonate (PC), polyamide (PA), and polybutylene terephthalate (PBT).

• PET plastic has high mechanical strength, can withstand tear and impact force, is abrasion resistant, and has high rigidity.

• PET plastic is transparent and inert to the food environment.

• PET plastic is more resistant to oxygen and carbon dioxide gas than other plastics.

• The chemical structure of PET remains unchanged when heated to 200^oC or cooled to -90^oC, and the gas impermeability remains unchanged when the temperature is around 100^oC.

Applications of PET Plastic:

• PET is used to make bottles, bottles of pure water, and carbonated soft drinks due to its extremely high waterproofing properties. Furthermore, due to its air permeability and high-temperature safety, PET is widely used in the production of shaped plastics and plastic food trays.
