HBM Packaging & Plastics Technologies supplies a new line of hot-fill bottles recently introduced by SIPA of Veneto, Italy, a global leader of stretch blow moulding machines for the production of PET bottles.
The new hot-fill bottles are a result of two years of development and eliminate the need for vacuum absorption panels.
SIPA has created bottles, production and hot-fill systems for cylindrical containers of various shapes, which have a petaloid base, are panel-free and can be labelled with a regular wraparound label.
The application was created by SIPA to help their customers reduce the cost of their primary packaging (bottle, cap and label) while still using hot-fill technology that ensures that their products retain high standards without the need for preservatives.
Liquid is filled into the hot-fill bottles at 85ºC - 87ºC, and a dose of liquid nitrogen is injected immediately prior to the capping, which results in 1.5 bars of internal pressure. After the beverage has cooled and its volume has contracted, the internal pressure remains at 0.2 - 0.3 bars, ensuring rigid packaging and ease of labelling.
Wraparound labels, which cost 30% less than typical shrink labels can be used on these hot-fill bottles helping to achieve cost savings.
Additionally, lighter weight containers can be used for filling due to the elimination of the side panels.
SIPA is represented in Oceania by HBM Plastics & Packaging Technologies.
