Abstract

La présente invention concerne généralement le domaine des objets tridimensionnels à base de cellulose, par exemple des matériaux d'emballage à base de cellulose. En particulier, la présente invention concerne des objets moulés à base de cellulose ayant une surface fonctionnalisée, par exemple une surface qui réduit l'absorption d'eau. Un mode de réalisation de la présente invention concerne un objet moulé à base de cellulose comprenant une couche de gel de cellulose. Par exemple, la couche de gel de cellulose peut être obtenue par sulfuration.
