PET bottles are generally produced by a process called injection stretch blow moulding (ISBM). In this process, preforms blown into the PET bottle mould are deformed in two directions, radially by the internal pressure and axially by the stretch rod. The air pressure loading consists of two consecutive stages, the pre-blow and final-blow.

PET Use in Blow Molded Rigid Packaging - ScienceDirect

Polyethylene terephthalate (PET) bottles were commercially introduced to the market place for the first time in 1976, by Pepsi Cola. The bottles were supplied by Amoco from their Seymour, IN plant, blown on Cincinnati Milacron machines, from preforms molded in molds supplied by Broadway Mold in Dayton, OH.
