Genius Isothermal Extender

Code 770BLA
Introducing the Polibox® Genius Isothermal Extender – a premium food transport solution designed for professional caterers, bakeries, patisseries, and hospitality businesses. Manufactured from high-quality BPA-free and melamine-free expanded polypropylene foam (PPE). This eco-friendly material is made up of 98% air and is fully recyclable.

Suitable for direct contact with food, it does not transfer odours or flavours, helping preserve the freshness and quality of cakes, desserts, and catering items. The extender is also dishwasher safe for easy cleaning and long-lasting performance.

Perfect for transporting cakes of different sizes and heights up to 80 × 80 cm, the Genius modular system features an innovative interchangeable base and lid design.
