WEB EXCLUSIVE: Eastman Chemical Co., Kingsport, Tenn., last month launched a new resin and a new trade name for a family of copolyesters aimed at high-clarity, multi-serve beverage, spirit, and dairy packaging. The new Aspira family is aimed at extrusion blow molding of handleware and other bottles of 48 oz and larger. It includes the former Eastar EB062 copolyester, which has had five years of success in shuttle blow molding. It is joined by new Aspira EN177 copolyester, whose rheology is tailored to extend the processing range to include higher-output machinery of wheel and reciprocating-screw types, as well as shuttles. Like EB062, the new grade is a modified PET. Aspira resins offer much higher clarity than polyolefins and greater design freedom than stretch-blown PET. The two Aspira grades are very similar in physical properties. However, EN177 is said to be more compatible with the PET post-consumer recycling stream, with less tendency to cause gels or black specks.
