Milestones in PET expertise
1967
Stretch blow molding technology is born
Machine manufacturers Heidenreich & Harbeck focus on innovation and invest in the development and engineering of a high-performance blow molder which produces plastic bottles for beer – then made of PVC.
1971
Premiere for PET
Dupont presents what is to date a secret material which demonstrates much better properties than PVC and paves the way for the success of the plastic bottle – stretch blow-moldable PET. As early as in May 1971 Gildemeister starts to develop a high-capacity rotary machine for the stretch blow molding of PET bottles.
1975
Founding of Corpoplast
The first series of high-performance stretch blow molders is ready for market. The recently founded Corpoplast company is the manufacturer of these high-quality machines.
2000
Success has a name: Blomax
The top technology of the stretch blow molding model, which has long successfully established itself on the market, is constantly further developed. In its third generation it gains the new name of Blomax Series III.
2002
Launch of PLASMAX barrier coating
The next innovation conquers the market: a system for the barrier coating of PET bottles celebrates one success after another. Under the name of PLASMAX it has been jointly developed by SIG and HiCotec (Schott AG). Following a number of scientific awards and approval by the FDA industrial tests at Bischofszell Nahrungsmittel AG are not long in coming.
2008
Corpoplast and Plasmax join the KHS Group

Premiere of the InnoPET Blomax Series V
Even more resources saved through intelligent processing systems during preform heating and in the stretch blow molding process. A maximum of 36 blow stations with a specific capacity of up to 2,500 containers per hour/blow station, suitable for practically all standard plastic, bio-based or rPET containers.
