Swedish speciality chemicals company Perstop has announced that its new high-clarity thermopolymer line – Akestra – has now been certified as fully ‘fully safe for use in food packaging’ in the EU.

The move was announced on 14 September. The central step that has now been completed is having the key monomer in Akestra added to Regulation 10/2011 on plastic materials and articles for food contact use.

Perstop is positioning Akestra as an alternative to polycarbonate, polystyrene and glass; but principally polyethylene terephthalate (PET) in hot-fill packaging. This is based on its superior heat resistance and transparency that can give a ‘glass-like’ appearance according to the developer. Akestra can also be combined with up to 80% recycled PET to improve environmental performance.

Perstop product manager David Engberg says: ‘Akestra is a unique family of plastics that will open up a whole new range of applications for polyesters. It is an excellent choice for demanding applications, like hot-fill and hot food serving. We expect it to be used primarily in disposable packaging.’

The developer notes the new thermoploymers can be processed on existing PET manufacturing equipment with minimal changes.
