How are milk bottles made

The process of bottle making begins with an initial blank piece of PET, or polyethylene terephthalate. This is then heated until it reaches a certain point, after which it is pulled apart into smaller masses called chips. These chips are then melted down and injected into the bottle-making machine as a semi-solid mass. The machine helps to form these masses into bottles by blowing hot air and liquid plastic around them in various patterns until they have taken on the desired shape. They are then cool down and finished off with a label.
