PET plastic has the characteristics of light weight, high transparency, impact resistance, and not easy to break. It also prevents carbon dioxide gas, keeping the soda "steam". Therefore, PET plastic is suitable for bottling equipment, especially for water and soft drinks!

PET bottles are mainly used for the packaging of medicines and carbonated beverages, as well as the packaging of liquids such as alcohol, tea drinks, fruit juices, mineral water, edible oils, condiments, cosmetics, pesticides and detergents. PET bottles have many advantages as pharmaceutical packaging containers.

First of all, PET bottles have the advantages of light weight, easy molding and strong bottle body. Its strength and elasticity are significantly higher than other plastic materials, and can withstand considerable impact without damage. Suitable for thin-walled, light-weight, high-strength pharmaceutical packaging bottles. After the advent of PET bottles in my country in the early 1980s, it developed rapidly. In just over 20 years, it has become the world's foremost packaging container for liquids and solids. In the field of pharmaceutical packaging, when the loading volume is the same, the weight of the PET bottle is only about 1:10 of that of the glass bottle, and the capacity of the PET bottle is 1.5 times that of the glass bottle of the same diameter. Transparent or translucent brown bottles can be made from PET raw materials.

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

The recovery rate and utilization rate of PET resin are higher than other plastics. When used for waste combustion treatment, it is flammable due to its low combustion calorific value and does not produce harmful gases.

Food packaging made of PET meets the requirements of food hygiene, because PET resin is not only a harmless resin, but also a pure resin without any additives. It has passed the inspection of fairly strict food hygiene laws including the United States, Europe and Japan, and is considered to be a qualified and safe packaging material for medicines and food. These advantages make PET bottles the best among plastics.
