Circular Beverage Packaging

'Zotefoams' is a UK-based food packaging company that created 'ReZorce,' a fully circular beverage packaging alternative to replace traditional plastic sources. ReZorce uses 'High-Density Polyethylene' (HDPE) in a multi-layer structure to ensure the preservation of the beverage within. The HDPE foam layers are used in favor of a large, single layer because the insulating properties of a multi-layer package are much greater.

The multi-layer HDPE model also allows for Zotefoams to account for a shortage of high-quality materials. Should this shortage occur, Zotefoams can insert other recyclates within the inside layers, as these layers never come in contact with food. Additionally, any recyclate substitution still results in ReZorce packages being fully recyclable. ReZorce foam also includes microbubble technology, which allows for the cartons to be folded without breaking, unlike more traditional foam products.

Zotefoams has also stated, quite notably, that ReZorce foam could be used in materials aside from drink cartons. These applications include pouches, tubes, and several other structures, so the potential of ReZorce foam is expansive. The largest barrier that ReZorce currently presents is the smoothness of the outer layer, which currently has a slightly rough texture caused by the foam. Zotefoams is actively looking into a sustainable solution to this barrier.
