SIPA of Veneto, Italy specialises in a range of stretch blow moulding machines for the production of PET bottles.
 
SIPA has now used its expertise to develop a new 18.9-litre PET bottle with an embedded handle also made from PET, making it totally recyclable.
 
SIPA engineers took on the challenge of designing the large, yet lightweight PET bottle following market concerns over the use of BPA (residual bisphenol A) in bottles, particularly in large water cooler bottles. The engineers initially produced a 690-gram bottle with a polypropylene handle. The weight was further reduced by 25 grams by developing a preform with a lightweight neck and base, and adding material in the area of the body where the handle is attached during the blow mould process.
 
Since the handle is also produced using PET in place of polypropylene, there is no need to separate the two pieces for recycling.

The new PET bottle design with integrated PET handle is produced on a SIPA SFL 2/2 two cavity linear stretch blow moulding machine at speeds of up to 250 bottles per hour per cavity, which is around three times more than that achieved with polycarbonate bottles, to provide further cost savings.
 
SIPA is represented in Oceania by HBM Packaging & Plastics Technologies .
