For the purpose of this study, the process "tap water, at user" was used for the water filled in the bottles. Classification of processing methods 1. Pet Bottle Production Raw Material. Later, the hot air pushes and expand the plastic against the mould to form the desired mould shapes. Blow molding is a manufacturing process by which hollow plastic parts are formed.
