5-6 months - Start in February/March 2025 - The LGP2 and 3SR laboratories and the Centre Technique du Papier are working to develop a low-cost, bio-inspired approach to significantly reduce the weight of paper and cardboard packaging while maintaining its mechanical performance. One effective way of increasing the bending stiffness/weight ratio of a flat structure is to emboss or form a network of “ribs” on the surface. By printing a starch gel onto the surface of a paper, an embossed shape is obtained, which increases the flexural rigidity of the structure. This process aims to reduce packaging weight by around 30%, which translates into savings in raw materials and energy.
