Shelf life is chemistry controlled by engineering.
Our oxygen-scavenging PET preforms contain 1 % amorphous nylon dispersed at nano-scale, scavenging 2 ppm O₂ over 180 days and doubling the shelf life of sensitive juices.
For carbonated soft drinks, a 30 mm preform with optimised stretch ratios lowers CO₂ loss from 15 % to < 8 % over 16 weeks at 38 °C, outperforming standard PCO1810 necks.
In dairy, UV-block masterbatch at 330 nm prevents riboflavin degradation, preserving vitamin B2 levels above 90 %.
Combined with fluorinated neck rings that minimise flavour scalping, these innovations let brands expand distribution into tropical climates without refrigeration, opening new markets in Africa and Southeast Asia while reducing cold-chain emissions.
