PET plastic bottles

Plastic bottles have been around for a long time and have developed very rapidly. They have replaced glass bottles in many occasions. Now it has become a trend for plastic bottles to replace glass bottles in many industries, such as large-capacity injection bottles, oral liquid bottles, and food seasoning bottles. , cosmetic bottles, etc., mainly because it has many advantages:

1. Light weight: The density of the material used to make plastic bottles is low, and the quality of containers with the same volume is lighter than plastic bottles.

2. Low cost: Plastic can reduce raw material and transportation costs, so the total price is relatively cheap.

3. Good airtightness: the plastic is combined with a reliable airtight structure, so the interior can be effectively protected.

4. Strong plasticity: Compared with glass, the plasticity of plastic is greatly increased.

5. Easy to print. The surface of plastic bottles is easy to print, which is of great benefit in promoting sales.

6. Save time and labor: reduce the cleaning process of glass bottles, effectively saving labor costs. At the same time, the use of plastic bottles can also effectively reduce the noise pollution in the production process.

7. Convenient transportation: Plastic is lighter than glass, so it is easier to load and transport and load and unload goods, and it is not easy to damage.

8. Safe and durable: plastic is not as easy to damage as glass during transportation, storage and use.

PET plastic bottles combine the texture of glass bottles but maintain the characteristics of plastic bottles, that is, plastic bottles can achieve the appearance of glass bottles, but they are less fragile, safe, environmentally friendly, and easy to transport than glass bottles.

Secondly, medicinal PET bottles have good gas barrier properties. Among the commonly used plastic materials, PET bottles have the best water vapor and oxygen barrier performance, which can fully meet the special storage requirements of pharmaceutical packaging. PET has excellent chemical resistance and can be used for packaging of all items except strong alkali and some organic solvents.

Again, the recycling rate of PET resin is higher than that of other plastics. When it is burned as waste, it is flammable because of its low calorific value of combustion, and does not produce harmful gases.

The most important thing is that food packaging made of PET meets food hygiene requirements, because PET resin is not only a harmless resin, but also a pure resin without any additives, which has passed quite strict standards including the United States, Europe and Japan. test.
