09 Oct 2018 --- Sonoco has announced that it is now producing rigid paper containers as the new exclusive supplier of the German muesli manufacturer mymuesli. The packaging solution is ideally suited for both online distribution and through brick-and-mortar shops and provides superior product protection. The wall and bottom are equipped with a barrier film that replaces the conventional aluminum. This enhances the gas-tightness so that the quality, taste and nutritional value of components like grains, nuts and berries are preserved for longer.
