In many fields, PET plastic bottles are an important form of packaging. Beverages, food, cosmetics, pharmaceuticals, daily necessities, and chemical raw materials can all be stored in plastic bottles. Plastic products have been integrated into our daily lives, and they can be seen everywhere. The demand for plastic products in the packaging market is increasing day by day.

PET is commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol, collectively referred to as thermoplastic polyester or saturated polyester along with PBT. PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Good creep resistance, fatigue resistance, friction resistance, and dimensional stability, low wear and high hardness, with greater toughness in thermoplastic materials; Good electrical insulation performance, less affected by temperature, but poor corona resistance. Non toxic, weather resistant, stable against chemicals, low water absorption, resistant to weak acids and organic solvents.

Disposable PET plastic products have occupied a considerable market share, and the quality of plastic bottles is also constantly improving.

The importance of plastic containers is gradually becoming prominent, not only in the beverage market, but also in the food, cosmetics, and pharmaceutical industries. The development of new filling technologies and heat-resistant PET bottles has opened up new possibilities and choices.

PET bottles are widely popular in beverage, cosmetic, and bathroom product packaging, while detergent packaging mainly uses PE plastic bottles. In addition, PE is also widely used in milk bottles.
