What is PET :
PET or PolyEthylene Terephthalate is a great material for producing pure, healthy and food grade containers. Sparkling bottles with almost glass like ﬁnish can be produced using it. It complies with most of the food materials and do not affect the physical appearance, taste or odour. It is unbreakable, tough and incredibly convenient for production and storage. Due to high sustaining capability, it is ideal for storing carbonated products. It has quite low permeability to gases and humidity increasing shelf-life of products. Due to high-chemical resistance it is a good package material for harsh chemicals and acid. Lightweight, high-strength and leakproof PET bottles and containers offer an ideal substitute for glass. It is possible to mold containers of any shape, design, and colour and neck size. High recyclability and reusability ensure less environmental impact. It gets decomposed into carbondioxide and water and no chemical residuals are produced.
PET is an excellent water and moisture barrier material. Plastic bottles made from PET are widely used for packaging water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. . PET plastic possesses characteristics such as durability, good clarity, and tends to be impact resistant.
