PET represents POLYETHYLENE TEREPHTHALATE. PET, which stands for polyethylene terephthalate, is a type of form of polyester that is synthetically processed fiber that is used for a wide range of industrial applications that include storage containers and electrical components. PET resembles natural fiber. PET is extruded for fibers and can be molded into plastic bottles.PET is thermoplastic in nature and gets influenced by temperature when heated.
Advantage of PET
PET is plastic in nature.PET is a highly valued packaging material owing to its physical parameters. PET is strong but possesses lightweight, Chemically PET is non-reactive. PET is economical to manufacture and owing to low density can be blown to the film like sheets
PET is not brittle and is shatterproof. Owing to low reactivity PET’ is used for food storage safety for food, beverage, personal care, pharmaceutical, and medical applications is recognized by health authorities around the world.
PET as storage container
Owing to the low reactivity and inert nature of PET, PET containers are popular for packaging food grade products. PET packing is done for edible grade items. Water, sodas, water bottles, juices bottles, salad dressings, cooking oil, shampoo, liquid hand soap, chemicals, pharmaceuticals are stored in PET containers. Moreover, milk too that constitute of lactic acid does not react with
PET.
PET Manufacturing
PET is a polymer of ethylene glycol and terephthalic acid. Pellets of PET resin are heated in an autoclave under pressure to arrive at a molten liquid. This liquid is transparent. At molten state, the colloid can be extruded to fibres or moulded into any shape.

Physical Properties of PET
PET (POLYETHYLENE TEREPHTHALATE) is a polymer. PET has lots of industrial advantages owing to its physical properties. PET materials are thermoplastic. They are electrical insulators and are used as a dielectric. Owing to low weight to high strength they are used in the manufacture of containers for both food storage and transportation.
Chemical Properties of PET fibres
PET polymers can be moulded under influence of temperature. This helps in the recycling process and the reuse process. PET material is highly stable under influence of fluids that include water, milk, and biomaterials like blood.
Industrial applications
PET owing to its properties are largely used in industries. Ropes, support structures, electrical components, medical devices use PET. The recycling property of PET is noteworthy. Water repellent properties, optical properties help in industrial applications.
