Plastic bottle manufacturers

The manufacture of plastic bottles takes place in stages. Typically, the plastic bottles used to hold potable water and other drinks are made from polyethylene terephthalate (PET), because the material is both strong and light. To understand the manufacturing process it’s helpful to first examine the composition and how this affects plastic bottles.

The first stage in bottle manufacturing is stretch blow molding. The PET is heated and placed in a mold, where it assumes the shape of a long, thin tube.

(The process by which the plastic is forced into the mold is called injection molding.) The tube of PET, now called a parison, is then transferred into a second, bottle-shaped mold. To ensure that the bottom of the bottle retains a consistently flat shape, a separate component of plastic is simultaneously joined to the bottle during blow molding.
