1. Characteristics of PET materials

physical properties
Good mechanical properties: It has high strength and toughness, is resistant to stretch and impact, and can replace some metal and glass materials to a certain extent.
High transparency: The transparency of PET material is comparable to that of glass, which can clearly display the contents of the package and increase the appeal of the product.
Good stability: It has certain tolerance to water, oil, acid, alkali, etc., and is not easily corroded.
chemical properties
Chemical resistance: It can resist the erosion of various chemical substances, ensuring the safety of the packaging contents to a certain extent.
Non-toxic and odorless: meets the hygienic requirements of packaging materials such as food and medicine.
Processing characteristics
Strong processability: Products of various shapes and specifications can be made through injection molding, extrusion, blow molding and other processing methods.
Short molding cycle: high production efficiency, which helps reduce production costs.

2. Use of PET materials

Packaging field
Food packaging: widely used in beverage bottles, mineral water bottles, edible oil bottles, etc. Packaging bottles made of PET material have the advantages of good sealing, light weight, not easy to break, etc., and are convenient for transportation and storage. At the same time, its transparent appearance allows consumers to intuitively see the food inside the package, increasing their desire to buy.
Pharmaceutical packaging: used for pharmaceutical blister packaging, infusion bottles, etc. The stability and chemical resistance of PET material enable it to ensure the quality and safety of pharmaceutical products.

Cosmetic packaging: packaging bottles for cosmetics such as perfume, lotion, etc. The high transparency and good appearance of PET materials can enhance the quality of cosmetics.
Electronic and electrical fields
Electronic product accessories: such as mobile phone cases, computer monitor cases, etc. PET material has good insulation properties and mechanical strength and can protect electronic products from the external environment.
Electronic films: used to manufacture capacitors, insulating materials, etc. PET film has good electrical properties and heat resistance and can meet the special requirements in the electronic and electrical fields.
Textile field
Polyester fiber: PET material can be processed into polyester fiber, which is widely used in clothing, home textiles and other fields. Polyester fiber has the advantages of high strength, good wear resistance, and resistance to deformation. It also has good dyeing properties and can be made into textiles of various colors.
Other areas
Car interior: such as seat fabrics, dashboards, etc. The abrasion and weather resistance of PET material allows it to adapt to the complex environment inside the car.
Building materials: used to make roof tiles, insulation materials, etc. The corrosion resistance and waterproof properties of PET materials make it have certain application prospects in the construction field.

In short, PET materials play an important role in various fields with their excellent properties and wide range of uses. With the continuous advancement of science and technology and the increasing demand for environmentally friendly and high-performance materials, the application prospects of PET materials will be broader.
