This video shows a detailed process of how PET bottles are crafted. The bottle begins it journey as a mold which is then mounted onto the PBBM (Pet Blow Bottles Machine) to be carefully constructed into a bottle through a process of being heated up to melting temperate between 254 -256 C. A remarkable transformation takes place when injection molded PET is stretched at the right temperatures and to the right extent. The long chains undergo strain-hardening and strain-induced crystallization, which gives the properly-made PET bottle exceptional clarity, resistance to internal pressure, uniform wall thickness, toughness, and a host of other features.
