Application of PET plastic bottle:
　　PET plastic with light texture, high transparency, impact resistance is not easy to break, and other characteristics, easy to transport and other characteristics, mostly for the final sterilization of oral liquid preparation and oral solid preparation.
　　PET bottles are mainly used in the packaging of pharmaceuticals and carbonated drinks, and can also be used in the packaging of liquor, tea drinks, fruit juice, mineral water, edible oil, spices, cosmetics, pesticides and detergents.
　　As a pharmaceutical packaging container, PET bottles have many advantages.
　　First, the polyester bottle light weight, easy to form and solid bottle. The utility model has the advantages that the strength and the elasticity are obviously higher than that of other plastic materials, and the utility model can bear considerable impact force and is not damaged, and is the most suitable to be used as a thin wall, light weight and high strength medicine packaging bottle. PET bottles in China at the beginning of 80s after the advent of century, with the rapid development momentum of can't be held back. In a short span of 20 years, it has become the world's most liquid and solid packaging containers. In the field of drug packaging applications, in the case of the same volume of drug loading, PET bottle weight is equivalent to about 1 / 10 of the glass bottle; the same diameter of the packaging bottle, PET bottle capacity of glass bottles is 1.5 times. Transparent or opaque brown bottles can be made with PET material.
　　Second, medicinal PET bottle has good gas barrier property. In the commonly used plastic materials, PET bottle barrier water vapor, oxygen performance is the best, can fully meet the special packaging requirements of pharmaceutical packaging. PET has excellent chemical resistance and can be used for the packaging of all items except for strong alkali and some organic solvents.   third, the recovery of PET resin utilization rate higher than other plastics, as waste combustion process, because of its value and low calorie burning flammable, and does not produce harmful gases.
　　At present, the world's polyester production is growing at a rate of two digits. The medicinal PET plastic bottles made of polyester as the main raw materials have become the most mainstream medicine, health care products and food packaging containers.
　　How to sort PET bottles and PVC bottles?
　　If PET bottles and PVC bottles are mixed together, here are transparent bottles. PET bottle molding is carried out in two steps, that is, the first injection molding and blow molding, so each PET bottles have a lower end of the injection mouth, take a look at the know. PVC is a blow molding, without the need for injection molding, so no injection mouth. So a bottle with a material injection mouth is PET, no PVC.
　　The characteristics of plastic bottles:
　　High transparency, light transmittance can be up to 90%, on the packaging of goods have good display function.
　　High barrier property and good fragrance, and low transmittance of O2, CO2, water vapor to PET.
　　Good chemical stability, oil resistance, fat resistance, acid resistance, alkali resistance, resistant to most solvents.
　　PET plastic bottle has excellent low temperature performance, can be used in -30 -60 C C.
