Abstract

L'invention porte sur une pellicule hydrosoluble apte au thermoscellement conservant son état au moment du thermoscellement même en atmosphère sèche, et sur un emballage alimentaire, cosmétique, médical ou chimique utilisant une telle pélicule. Ladite pellicule hydrosoluble comprend: un ou des polysaccharides hydrosolubles sans groupe sulfate, un ou des polysaccharides hydrosolubles à groupes sulfate, et un ou des composés hydroxy servant de matériau d'humidification, tout en étant pratiquement exempte d'agents réticulants. Après thermoscellement la pellicule donne une partie thermoscellée ne subissant pratiquement pas de séparation dans des conditions d'équilibre d'humidité, et pour une humidité relative de 25 % ou moins.
