KINGSPORT, TENN. (Oct. 3, 2:15 p.m. ET) — Eastman Chemical Co. has debuted a polyester specifically designed for extrusion blow molding and recyclability.

The properties of the new Aspira polymer make it processable at high speeds and gives it shelf appeal for large container applications. Packaging designers can exploit Aspira’s clarity, strength, processing ease and flexibility in a sustainable polymer.

Kingsport-based Eastman said the resin is compatible with the PET recycling stream, and in July the Association of Postconsumer Plastic Recyclers said it met the group's PET Bottle Critical Guidance Document protocol.

The resin boasts lower scrap rate and energy demand and is a clear and glossy glass alternative. Its integrated clear handle possibilities extend its end uses. It is robust, bisphenol-free and also doesn’t contain antimony or halogens.

Compared to EPET, Aspira has no haze, gels, degradation in processing and has a low drying temperature of only 60° C. It is an amorphous regrind type similar to pellets and gives bottle toughness, according to Eastman.
