Abstract

La présente invention concerne la fabrication d'un matériau biodégradable capable d'être formé en une feuille fine convenant à de nombreux emplois. Le nettoyage du matériau de feuille est rapide, facile et bon marché, étant donné que ce matériau est biodégradable. Dès qu'on n'a plus besoin du matériau de la feuille, il suffit de le pulvériser avec de l'eau, ou de le mettre en contact d'une façon ou d'une autre avec de l'eau, pour dissoudre le matériau en ses composants constitutifs.
