Abstract

Cette invention concerne un film qui est doté d'une grande stabilité au stockage, même en atmosphère très humide, et qui est agréable au toucher; un procédé de fabrication pour ce film; et un film de conditionnement qui renferme un parfum et qui dégage donc une odeur agréable lorsqu'on l'ouvre ou qu'on le dissout. Ce film comprend une pellicule hydrosoluble et un matériau insoluble dans l'eau sur une de ses faces. Le matériau insoluble dans l'eau représente de 0, 1 à 80 parties en poids pour 100 parties en poids du film hydrosoluble et se présente sous la forme de paricules dont le diamètre moyen est de 500 νm ou moins, ou sous la forme de fibres d'une longueur comprise entre 10 νm et 6 mm. L'invention concerne également un produit de lavage dont les emballages individuels sont constitués par ledit film. Le procédé de fabrication de ce film consiste plus précisément à fixer le matériau insoluble dans l'eau sur une face de la pellicule hydrosoluble par application en couche ou par impression.
