PET preform is called "polyester resin", which is applicated highly in the packaging of food, as it is an odorless material. Food as an eligible, something to eat, so that the package is very important.
Food, for which the vast number of consumers pay attention to its quality problems,if stays in the air long time, it would be deteriorated. However, if the food wrapped with PET bottle material, it can be protected well, because PET can block ultraviolet light, and block water, oil, air and etc. Generally speaking, PET has a relatively low permeability to gas and water vapor.
Moreover, PET has a relatively stable physical function, featuring oil resistance, corrosion resistance, and folding resistance. It also has a strongly high temperature resistance. All this laid a foundation on a kind of food protection material. PET can be used not only for food packaging, but also for PET bottle preform material, of which principle is the same as food, with high temperature resistance, UV resistance, air isolation and other excellent conditions, becoming an important link in processing. With these features, we can completely make assured of PET bottle preform, which is not harmful to our health, and we can be no worry for high temperature to make the product worse.
