PET Bottles

What is PET?

PET (PolyEthylene Terephthalate) is a strong but lightweight form of clear polyester. It is used to

make containers for soft drinks, juices, alcoholic drinks, water, edible oils, household cleaners, and

other food and non-food applications.

PET Bottle Process Flow

The PET resin, in the shape of small cylinders called pellets, is melt and injected into a mould to

make a preform. The preform, a sort of test tube shorter than what the bottle will be but with

thicker walls, is then blow-moulded. During the blow-moulding phase, high-pressure air is blown into

the preform allowing it to take the exact shape of the mould it is set into. The final product is a

transparent, strong and lightweight bottle.
