Equipolymers: BPA-free PET for large bottles
Designed for large bottling applications including the home and office delivery (HOD) water bottle market, Equipolymers BISNEINEX polyethylene terephthalate (PET) resin is a new, cost-effective solution that maintains good aesthetics while eliminating any regulatory or consumer issues related to existing and developing bans of bisphenol-A.
BISNEINEX also has no impact on raw material cost and has potential to improve processing cost conditions due to lower energy use for large container sizes including 5 gallon and 20 liter applications. The PET is optimized specifically for injection molding, stretch blow molding, and injection stretch blow molding production of large volume containers (>3 liters) that require thick-walled preforms and reduced crystallization rate.
BISNEINEX also provides: a large processing window due to reduced recrystallization behavior; improved bottle thermal stability (low shrinkage); improved color in the final application; and high drop test and top load performance.
BISNEINEX requires very minimal changes to existing manufacturing processes, and can be used on PC lines with only minor modifications to the equipment.
