Akestra™ 90

About
Akestra™ is a sparkling glass-like, heat resistant polyester that enables optimization and diversification of PET packaging production lines. Akestra™ is a sustainable material that enables food serving in a new, safe and visually appealing container that also improves brand security as brand owners can feel 100% secure in serving their products in Akestra™ packaging. Akestra™ 90 offers the best value in terms of mechanical properties for both cold and hot application, in the Akestra™ range. Still at a heat resistance superior to PET, as HDT is 11°C above PET. Akestra™ 90 also offers many opportunities as performance boosting additive as it is fully mixable with PET and PC without compromising with transparency.&&
