Serac has installed a blow-fill-cap machine in Brazil (Combox), for the packaging of 50g yoghurt portions presented in an attractive fruit-shaped PET flask.
High precision stretcg blow-moulding for tiny preforms
Blown from a PET preform of only 2.3 g, with nearly half of the mass concentrated in the neck, the fruit-shaped flesk requires an expansion rate of 16 (4 times in both length and width), which is extreme in this industry. On such tiny preforms, the SBL blower from Serac clearly demonstrates a high level of precision in heating, stretching and blowing operations.
With the new blow-fill-cap Combox unit in operation, Serac demonstrates the benefits as well as the versatility of its single block solution.
