TWO-STAGE PET BOTTLES:
A great alternative for…
The packaging world is a perfect example of an industry that continues to develop. Where formerly products made using the two-stage process were for mass production (E.g. in the soft drinks sector) and single-stage production was for annual volumes up to 10 million units, both production technologies now overlap each other more often. In principle, both technologies are similar, only the origination of the preform differs. The difference in the technologies is explained by the terminology.
In single-stage, the injection stretch and blowmoulding process takes place within one machine whereas in the two-stage process, the preform production is done by one machine and the blowmoulding in another machine. The scale benefits of preform production can give you a significant advantage in developing a new two-stage PET bottle or jar. By using mass produced preforms you only have to invest in a small blowmould to make your own bespoke model. Our PET specialists are happy to advise which method offers the most benefit for your packaging needs.
