PET bottles have almost monopolized medicinal oral liquid bottles and health care bottles, and once caused the price of raw materials to rise. What makes it so attractive? Is PET bottle really the best material, just like the rumors of the outside world?


First of all, the polyester bottle is light in weight, easy to form, and the bottle body is firm. The strength and elasticity are significantly higher than other plastic materials, and it can withstand considerable impact without being damaged. It is most suitable as a thin-walled, light-weight, and high-strength pharmaceutical packaging bottle.

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


Third, the recycling rate of PET resin is higher than that of other plastics. When it is burned as waste, it is flammable due to its low combustion calorific value 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. It has passed quite strict standards including the United States, Europe and Japan test.
