Varieties of PET Flakes: Hot, Cold, and Unwashed High-density polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. This is usually used in the production of plastic bottles. PET bottles go through treatment process and PET Flakes are produced as a result. The treatment process includes crushing, washing, separating and drying. PET Flakes are used as an alternative raw material to polyester. The raw material is used in producing a range of products. PET has several advantages such as (a) non-toxic (b) low water absorption (c) organic solvents (d) weather resistance (e) resistance to weak acids (f) anti-chemical stability (g) little affected by temperature etc. South Korea, India, China are some of the main markets for PET flakes.
