Eastman introduces new recyclable EBM resin for beverage packaging

Eastman Chemical Company has launched a new PET resin, Aspira One, for extrusion blow molding (EBM) applications such as clear handleware and large-size bottles.

Aspira One carries resin identification code 1 (RIC 1), meaning it is compatible in the PET recycle stream. It has received resin recognition from the Association of Postconsumer Plastic Recyclers (APR) in July 2012 for meeting the PET Bottle Critical Guidance Document protocol.

According to Eastman Chemical, the new polymer enables the design of unique, clear and glossy containers, such as handles, through holes and other innovative features that can only be obtained by the EBM process. For bottle performance, the material offers robust toughness and crystal-clear clarity. It is also free of bisphenol A and halogens.

As different from other polyester resins for EBM, Aspira One is an amorphous, melt-phase produced material. Because the pellets are not crystalline or solid-stated, they can be dried and processed at lower temperatures than other PET resins. This lowers energy usage, improves melt quality and minimizes thermal degradation of the polymer.

Another feature is that crystallization of bottle flash regrind is not required, because Aspira One pellets are amorphous and thereby compatible with the regrind in a dryer setup. In addition, the material does not melt fracture at high extrusion rates, giving it high clarity on all EBM platforms.

"Aspira One polymer provides the straightforward solution leading converters and brand owners are looking for," said Ron Salati, Global Market Development Manager, Specialty Plastics Packaging, Eastman. "In fact, major global beverage companies are expected to use Aspira One bottles starting in 2013."
