Manufacturer of PET stretch blow moulding machines for the production of PET bottles, SIPA has developed lightweighting technologies for hot fill PET bottles used in the juice, tea, isotonic and flavoured-water markets.
Sipa has been involved in ongoing weight reduction development for hot fill PET beverage containers over the past eight years for both single- and two-stage technologies. Depending on the technology chosen in conjunction with the bottler’s filling process, bottle weight reductions of up to 30% are being achieved.
Capable of being filled at up to 90°C with modern filling equipment, Sipa can significantly reduce the weight of the traditionally heavy hot fill PET bottles.
As an example, a Sipa customer in Vietnam is producing 26 g, 500 mL bottles filled at 88°C using a 38 mm non-crystalline reinforced lightweight neck finish. Typically, the same bottles in the Australian market are in the 32-35 g range.
Bottlers can save approximately $200,000 per annum for every gram reduction on a filling line operating at 24,000 bph on a continuous production basis.
