Difference and application of PET and RPET
The difference between PET and REPT, first of all, from the source, PET is a kind of primary plastic, which comes from petrochemical raw materials. While RPET is a recycled plastic, which is made by recycling, cleaning, crushing, melting and re-granulating used PET products (mainly beverage bottles), so RPET will also have a special global recycling standard certification, referred to as GRS certificate. The difference in source also makes the price of PET and RPET very different. The raw material price of RPET is higher, and the unit price of the products produced will be higher than that of PET. In terms of performance, PET has stable performance, high strength and good transparency, and RPET performance is close to that of native PET, but its thermal stability may be slightly lower, so it usually needs to be mixed with raw materials to ensure its performance.
Application of PET and REPT. PET is widely used in blister packaging industry, food packaging (such as fruit boxes and egg trays) and electronic product packaging and so on. PET Sheet is also commonly used for printing, such as UV printing, offset printing and silk-screen printing. The application field of RPET is highly coincident with that of PET, but it is more prominent in industries that pursue sustainability and environmental image.
In a word, PET is the basic plastic material of modern life, and RPET is its "green upgraded version". With the promotion of global circular economy and the goal of "double carbon", the application scope and market share of RPET are rapidly expanding, which has become the key path for the sustainable development of plastic industry.
