Best Answer

Blanks are created that are smaller and thicker than the finished product. Blank are inserted into the feed of a molding machine where they are places into a mold, heated up, and are expanded by blowing air pressure into the heated blank. This makes the blank take the shape of the mold.
The plastic bottle is usually manufactured in stages. The first stage of the plastic bottle manufacturing process is the stretch blow molding. The molten bottle is then usually subjected to pressurized air, heat and pressure and then molded to a specific shape.

From recycling.
