一、絕大多數使用PET塑料瓶原因有以下幾點：

1 Lightweight and inexpensive
Compare with glass bottles of the same size:

Comparison with glass bottles of the same size

2 High mechanical strength

PET bottles are better in terms of drop strength, impact strength and tensile breaking strength.

Know from the data, PET bottles (polyester bottles) in the bottle wall thickness is only half of the polyvinyl chloride bottles, but the impact strength of the drop hammer is twice as big, tensile breaking strength is more than three times as big.

3 Good airtightness, good fragrance retention

Pet plastic bottles with good air tightness

PET plastic bottle 38 ℃ temperature, oxygen permeability of 10.2mL / (m 2 - d), water vapor permeability is 1.1g / (m 2 - d), airtightness is better than polypropylene, polystyrene, polyvinyl chloride these plastics.

4 Good chemical stability

PET plastic bottleResistant to a variety of chemicals, such as ethanol, chloroform, carbon tetrachloride, acetone, etc., and does not contain plasticizers and antioxidants, and thus excellent hygiene, in line with the FAD standard, in the United States, Japan, etc. have received wide recognition.

5 Good transparency, glossy

PET plastic bottles combined with the texture of glass bottles but maintain the qualities of plastic bottles, that is, plastic bottles can do the appearance of glass bottles, but more than glass bottles with unbreakable, safe, environmentally friendly, good transportation advantages.

6 Recyclable

Glass, due to material limitations, manufacturing and recycling will produce a certain amount of environmental pollution. PET plastic bottles with the development of science and technology, has been able to be recycled after recycling and re-production, use, so as to reduce the damage to the environment.
