PET pioneers

Our company has always believed in having the courage to come up with innovative developments. The founding of Corpoplast in 1975 was preceded by a long and determined phase of pioneering work on the first high-performance blow molder for the manufacture of plastic bottles.

In 2008 Corpoplast joined the KHS Group, one of the world's leading suppliers of highly innovative filling and packaging systems with over 145 years of expertise in its field. Corpoplast’s decades of PET expertise perfectly complement the extensive KHS portfolio, with which we offer our customers the full range of products and services in filling and packaging technology – from the development of individual container design concepts through single machines to turnkey lines including round-the-clock service.

Milestones in PET expertise

Our focus is and always has been on developing sustainable containers with an attractive design, ever adopting a holistic approach to the manufacture, filling, labeling and packaging of PET containers throughout the entire filling and packaging line.

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

With the help of Corpoplast and Plasmax the KHS Group now offers the entire range of PET line expertise. Its specialist fields include comprehensive consultancy in PET bottle design and lightweighting right up to the construction of turnkey filling and packaging systems engineered to the latest standards.

2009

World premieres of the Blomax Series IV and stretch blow molder/filler

At drinktec in Munich, Germany, KHS presents the InnoPET Blomax Series IV. The high-performance stretch blow molder proves especially convincing with its output of up to 72,000 bottles per hour – at the time a world record. With its InnoPET BloFill stretch blow molder/filler block the KHS Group also has the first block concept for the filling and packaging of still water in PET bottles on display.

2014

KHS launches the world’s lightest 0.5-liter PET bottle with a screw cap for highly carbonated beverages to market weighing just 10.9 grams.

2016

Top innovations for future markets

Several new block concepts find their way onto the market, among them the TriBlock and InnoPET FreshSafe TriBlock. The opening of the new PET competence center is a further testimony to the company’s specialization in future-proof developments.

2017

Corpoplast and Plasmax merge

KHS Plasmax and KHS Corpoplast become a single entity. In doing so they pool their PET expertise and strengthen their position as a supplier of barrier, stretch blow molding and block systems.

2017

At drinktec 2017 KHS presents three PET world premieres:

InnoPET TriBlock Aqua M
This compact block system especially for single-serve formats offers a maximum output of up to 82,000 bottles per hour.

InnoPET Plasmax 2Q/4Q
The innovative PET-barrier coating especially suited to small companies and converters.

Five grams for 500 milliliters
The lightest 0.5-liter PET bottle known to KHS for still water is the result of a co-operation with Canadian injection molding machine manufacturer and world market leader Husky.
