Pet Bottle Cap Manufacturing Process

Polyethylene tetra phthalate is a polymer that is formed by combining two monomers called modified ethylene glycol and purified terephthalic acid.

Pet bottle cap manufacturing process.

The material normally used to make bottle caps is polyethylene. The raw material used in the manufacturing of pet bottles preforms is polyethylene terephthalate. The pet granulate is first melted at about 280 c and processed into what are called preforms. The manufacturing of pet bottles pet bottles are mainly manufactured in a two stage process.

Pet bottle production raw material. Plastic bottle manufacturing process. Plastic pellets are plasticized in the barrel of an injection molding machine where the plastic is melted by heat and the shearing action of a feed screw. Some caps such as 2.

These preforms already have the bottle cap threads and are small and easy to transport. Diethylene glycol and acetaldehyde a large amount of acetaldehyde in pet can posibly affect the taste when you drink out of the cap bottle must. Polyethylene terephthalate pet pet is polymerized to create long molecular chains two impurities during this proces. The first stage of a typical 2 step reheat and blow machine rbm bottle manufacturing process is injection molding.
