Transparent plastic bottle is a kind of blow molding processing for the color of all transparent milky white plastic through injection mold processing to produce the middle product bottle billet, and then through blow molding to produce plastic bottle, which is the basic principle of two-step forming. Transparent plastic bottle is a transparent bottle embryo mold produced by injection mold processing according to the special raw materials of polyester. The transparent bottle embryo mold is expanded in accordance with the mold size and model of the gun structure of the injection mold through blow processing under the special gas pressure and air temperature standards, and the transparent plastic bottle with the corresponding relative height and thickness is obtained. Transparent plastic bottles are used for pharmaceutical, drinks, purified water, candy bars, edible spices and other packaging bags. PET and PETG are widely used to produce plastic bottles through blow molding, which is also a three-step molding method. Bottle embryos are generated according to the injection molding of raw materials, and then the bottles are expanded according to certain specifications and models of the mold shell by heating and injection molding, so as to obtain the same thin and thick plastic bottles of relative height. The safety and reliability of PET and petg are very high, so in beverage and food enterprises, the use of these two secondary materials will be more; 1.PET material transparent plastic bottle characteristics: hard, good ductility, high compressive strength, surface smooth, environmental protection, non-toxic, transparent and a variety of color sheet.
