Just an idea to consider. We use paper packaging for flour, sugar etc. for decades. Why we use plastic for plenny shake? paper is fully biodegradable. Personally I would prefer one meal paper bags over big plastic resealable bags.
We need our products to have a long shelf life so the packaging needs to be water and air tight therefore our bags are a combination of PE and PET plastics. We want to contribute to sustainability by having the longest shelf life possible but we also want the maximum recyclability. It is a balance between those two things and we are in continuous conversation with our suppliers to have the best of both and trying different things to improve on this. Thanks for thinking about the environment it is our biggest ambition after making people their diet more healthy.
