What is PET Plastic Bottle

PET plastic bottles are not only widely used for packaging carbonated drinks, drinking water, fruit juices, enzymes and tea beverages, etc., but also the most used beverage packaging today, and are widely used in food, chemical, pharmaceutical packaging and many other fields. PET plastic has a wide range of applications in the packaging field, whether it is packaging film, roll material, or beer bottle.

The molecular structure of PET is highly symmetrical and has a certain crystallization tendency, so it has high film-forming and moldability. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance, friction, dimensional stability and electrical insulation.

PET plastic bottles made of PET have high strength, good transparency, non-toxic, anti-permeation, light weight, high production efficiency, etc., so they have been widely used.

The molecular chain structure of PBT and PET is similar, and most of the properties are the same, except that the main molecular chain has changed from two methylene groups to four, so the molecules are more flexible and the processing performance of PET plastic bottles is better.

Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles are widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, and after adding corresponding organic solvents, after high temperature heating, they are blow molded, extruded, or injection molded through plastic molds Plastic container.

It is mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oil, and agricultural and veterinary drugs. Plastic bottles are not easily broken, low cost, high transparency, and food-grade raw materials.

When using plastic products, pay special attention to avoid contact with vinegar, detergent, etc., and avoid direct sunlight, high temperature, etc., to avoid chemical reactions. In addition, when you buy plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, less decorative patterns, colorless, odorless, and smooth surface.
