(PlasticsToday) -- Bericap
has cut the weight of closures for edible oils in 1-liter bottles by 50%,
developing a range for 26-mm neck diameters that weigh only 1.37g compared to
2.74g. Bericap said the move was in response to an industry shift. In the past,
the heavier closures were needed on the standard 29/21 neck for 1-liter
containers when they were meant to fit glass and polyethylene terephthalate
(PET) bottles. Today, edible oils are primarily supplied in PET.
Bericap said the inner diameter of the new neck is identical to the
previous 29mm diameter, eliminating the need for modifications to filling
nozzles at the filler while still providing the same flow rate. The company
achieved the dramatic weight savings by cutting the inner diameter and the cap
height.
