Sainsbury’sAldi and the Co-op are set to start trialling fully recyclable sandwich packaging in partnership with supplier Greencore.

The all-fibre, plastic-free recyclable skillet, which will be 100% paper-based and feature a plastic-free window, will hit shelves across the UK from September. The new packaging is said to have no impact on shelf life.

The move follows 18 months of research and development in collaboration with flexible packaging manufacturer ProAmpac. If the trials proves successful, the new packaging will begin rolling out in stores nationwide later in the year.
