Internship offer at LGP2 - Feb-July 2026 - Paper and cellulose are promising materials for replacing plastic in the packaging sector. However, they still have limitations, particularly in terms of barrier properties (resistance to moisture, oxygen, grease, etc.). The intern will participate in the search for solutions and the study of barrier properties for flexible packaging used on a daily basis. Working closely with an industrial partner, he/she will explore innovative approaches to improving the resistance of these packaging materials to various environmental factors. The aim is to design packaging that effectively preserves the quality of the products it contains while complying with hygiene, sustainability and recyclability standards, thereby contributing to a transition towards more environmentally friendly solutions that comply with new regulations.
