Italian company SIPA (distributed in Australia by HBM Plastics & Packaging Technologies) has released four lightweight neck designs that are suitable for water, carbonated soft drinks (CSD) and hot-fill containers.
PMCI, the PET moulds and containers division of SIPA, has designed the necks for PCO 1810 standard CSD closures that use the same height as the 21 mm thread finish of standard designs, however offers 27 per cent material savings, bringing the individual weight down from 5.1g to 3.7–1.4 g per neck.
PMCI claimed the neck designs enable savings for 28 mm necks. The Hotlight 28 neck weighs 3.8g , half that of the standard 7.8 g. This design allows for the production of hot fill and CSD products on the same line, without any compromise to sealing.
