Perstorp: Plastic alternative

A high-performance co-polyester, Akestra from Perstorp can be used as a polystyrene replacement for heat resistant thin wall containers, a polycarbonate replacement for durable “dishwasher proof” transparent products, and a glass replacement for hot-fill food containers.

Developed in partnership with partnership with Mitsubishi Gas Chemical, Akestra can enhance both disposable and reusable packaging.  The high glass transition temperature, combined with its amorphous and high strength properties help make it an alternative in food packaging, and a material that can be easily blended with other plastics to improve their properties.

The high melt strength of Akestra makes it particularly suitable for extrusion blow molding as well as extrusion foaming processes. In combination with PET, it is said to create a finer cell structure allowing further weight savings with superior mechanical properties in structural and packaging foam applications.

When used in co-extrusion sheets for thermoforming, Akestra surpasses polystyrene heat resistance for hot-fill applications and, by using recycled PET, it can contribute to a more sustainable packaging solution with a lower carbon footprint, according to the company.
