The PITCH ! Laboratoire 3SR, LGP2 et CTP

Plastic is everywhere in our packaging… but can we replace it?
Here, a collaborative research effort between the 3SR Laboratory, LGP2, and CTP explores how paper could become an effective and environmentally friendly alternative.

The idea is simple and inspired by nature: shells and peanut husks have folds and bumps that make them rigid. Why not apply the same principle to bio-based packaging? To achieve this, researchers designed patterns of natural gels made from starch or nanocellulose printed onto the paper. As the gels dry, they induce paper deformation in the forms of structured bumps: the matter deforms and strengthens on its own, without any extra energy input!

The result: natural packaging that is five times stronger, as light as plastic… and quickly biodegradable
