Analysis of the advantages of PET plastic bottles

1. The reasons why most people use PET plastic bottles are as follows:

1. Lightweight and cheap
Compared with glass bottles of the same specifications:

Compared with glass bottles of the same specifications

2 High mechanical strength

PET bottles have better drop strength, impact strength and tensile strength.

From the data, we know that the wall thickness of PET bottles (polyester bottles) is only half of that of PVC bottles, but the drop hammer impact strength is twice as great, and the tensile fracture strength is more than three times greater.

3 Good air tightness and good fragrance retention

PET plastic bottles have good air tightness

When the temperature of PET plastic bottles is 38℃, the oxygen permeability is 10.2mL/(m²·d), and the water vapor permeability is 1.1g/(m²·d). The air tightness is better than that of plastics such as polypropylene, polystyrene, and polyvinyl chloride.

4 Good chemical stability

PET plastic bottles are resistant to a variety of chemicals, such as ethanol, chloroform, carbon tetrachloride, acetone, etc., and do not contain plasticizers and antioxidants, so they are extremely hygienic and meet FAD standards. They have been widely recognized in the United States and Japan.

5 Good transparency and gloss

PET plastic bottles combine the texture of glass bottles but maintain the characteristics of plastic bottles. That is, plastic bottles can have the appearance of glass bottles, but they are not easy to break, safe, environmentally friendly, and easy to transport than glass bottles.

6 Recyclable and reusable

Due to the limitations of the material, the manufacturing and recycling of glass will cause certain environmental pollution. With the development of technology, PET plastic bottles can be recycled and reused after recycling, thereby reducing damage to the environment.
