The oPTI process is based on MuCell technology licensed from Trexel, and is said to produce bottles with visual and tactile attributes.
Foboha GmbH and Ferromatik Milacron have joined PTI to improve speed-to-market and commercial viability for the oPTI bottles.
The Foboha cube mould system has been designed from the ground up to maximise cavitation and minimise cost for overmoulded parts. The goal was to increase production output criteria for the oPTI inner layer and an overmoulded traditional PET outer layer. Coupling Foboha’s cube mould technology with Ferromatik Milacron’s injection moulding platform results in an increased number of cavities in the mould, thereby significantly increasing the output.
“oPTI technology provides unparalleled appearance, with minimal chemical additives,” said Scott Steele, president of PTI. “This produces an ideal container for brand differentiation while still delivering recycling benefits. Brand owners will now have the combined expertise of PTI, Foboha, Ferromatik Milacron and Trexel supporting oPTI commercialisation.”
PTI says that the overmoulded oPTI bottle has been developed to deliver point-of-sale differentiation coupled with performance attributes at a cost significantly lower than single-use aluminium bottles, for example. Additionally, the technology can reduce the amount of expensive colourants used while still producing dynamic shelf appeal. The dual-layer structures also enable optimisation of barrier attributes. For example, oxygen barrier can be added to the inner layer, while the outer can include a carbon dioxide barrier.
In some categories, embossed overmoulded oPTI containers could even reduce costly label requirements. Ideal applications include foods, beverages (wine, spirits, beer, juice, nutraceuticals) health and beauty aids, and cosmetics.
