In terms of the policy for the development of plastic packaging, the first is to reduce the amount of plastic packaging waste, and to reduce the generation of plastic packaging waste, which should be the primary environmental strategy for plastic packaging. First of all, the design innovation of plastic packaging should be promoted, so that the plastic packaging can achieve lightweight or thin-walled plastic packaging while ensuring its basic functions. The technological advancement of the material synthesis process so far has been able to provide plastic varieties that can achieve this purpose.
Due to its good ductility, easy molding, and good stability, PET has a wide range of applications. In addition to food plastic bottles, plastic cosmetic bottles, plastic medicine bottles, etc. used in the daily life. It is also used in film and sheet series, such as daily shopping bags; as well as substrates for motion picture film, photosensitive film, etc.; electrical components, auto parts, mechanical equipment and other fields are also widely used.
The molding process of PET plastic can be injection molding, extrusion, blow molding, coating, bonding, machining, electroplating, vacuum metal plating, printing
PET plastic is the abbreviation of English, referred to as PET or PETP. The natural color of PET material is transparent, has good formability, and is easier to produce and process. PET is resistant to weak acids, has good stability under normal conditions, corrosion resistance and low water absorption, and also has good electrical insulation. But PET is not resistant to high temperature, even if it is a special high temperature resistant PET, the higher temperature it can withstand is only about 83 degrees. Therefore, PET products cannot be boiled, otherwise they will deform and release harmful substances.
