Krehalon has been awarded a Silver and Greenstar Sustainability Award at the 59th annual Starpack Packaging Industry Innovation Awards as recognition for the company’s success in developing a Mono-APET mince pack for the Co-op, in collaboration with Dunbia.
Krehalon gained two awards for its mono- material mince pack which offers superior environmental benefits over the conventional mince pack format.
“We are following closely the recent debate on plastics and our R&D team is concentrating every effort on trying to address issues with recyclability. This award- winning development shows our drive and commitment to align our offering with the principles of the circular economy,” said Glenn Dale, Sales Technical Manager for Krehalon B.V., UK Branch.
The current format of choice for modified atmosphere protein packaging traditionally uses polythene (PE) sealing mechanisms to enable secure seal of the film lid to the amorphous polyethylene terephthalate (APET),most common hard plastic used for food stuffs. This is a complex multi-material structure which makes protein packs more difficult to readily recycle.
Driven by Co-op’s ‘80% easy to recycle by 2020’ ambition, the key focus of the Dunbia-Krehalon partnership was to help simplify Co-op’s packaging for minced beef to one polymer type and help increase recycling at consumer level.
As a result, Krehalon-Dunbia developed a mono-APET pack structure using a specialist top web film which enabled the removal of the PE sealant layer and achieved a strong fused seal to the mono- APET base. Starpack judges described the development as ‘a great mono-material sustainability story with clearly defined future application potential’.
The success of this ipackaging development demonstrates that film technology is now readily available for retailers to pro-actively consider the removal of PE layers in their thermoformed pack formats, without compromising seal strength and pack integrity, whilst improving clarity and visual pack appearance. In the longer term, adopting mono structures will simplify the recycling chain and minimise the need for costly landfill or specialist recyclers.
