Marks & Spencer has launched a range of nuts in packs that combine transparency with high oxygen protection from Amcor Flexibles Europe.

The new packs feature a clear window surrounded by striking metallic inks. Camclear AIOx clear barrier polyester film and polyethylene was chosen to give comparable shelf life to the pack’s previous two-ply metallised polyester specification.

The film, produced by Amcor Flexibles Camvac of Thetford, is laminated and printed by the Amcor Colordense plant in Bristol.
