PET preform bottle is plastic bottle made from polyethylene terephthalate (PET) resin, which is a highly durable, transparent, and lightweight thermoplastic material. PET preform is produced through a process called injection molding. In this process, PET resin pellets are melted and injected into a mould, which is shaped like a tube with a narrow neck and a wider body. The mould is then cooled, and the hardened preform is ejected. The preform is then heated and stretched into the shape of the bottle. This PET preform bottle is commonly used for gulab jal, aloe vera gel, and other similar products.
