Bottles made from 7730 resin have high brightness and clarity in compared with antimony based bottles. The optimized recipe design of 7730 resin makes the crystallization of bottle neck effectively, and the lower generation of acetaldehyde and cyclic oligomer. Tairilin 7730 resin is especially suitable for heatsetting hotfill bottle with neck crystallization.
Tairilin 7730 resin is produced in a state of the art continuous polymerization technology and is combined with a strict quality monitoring system. The production facilities producing 7730 resin
are approved by ISO9001, ISO14001 and OHSAS18001 systems to confirm its outstanding quality of the product.
