Non gelatin film materials, e.g. hydroxy propyl methyl cellulose comprise e.g. an additive or additives such as an organic acid, e.g. hydroxy carboxylic acid, which form a barrier composition. The resultant films are safe human consumption and find use as a wall material of an ingestible delivery capsule, e.g. containing a dose of a pharmaceutical preparation.

L'invention concerne des matières de films non gélatineuses, telles que l'hydroxypropylméthylcellulose, comprenant, par exemple, un ou plusieurs additifs tels qu'un acide organique, et notamment de l'acide hydroxycarboxylique, et formant une composition barrière. Les films résultants sont sans danger pour la consommation humaine et trouvent une utilité comme matière de paroi d'une capsule administrable par voie orale contenant, par exemple, une dose d'une préparation pharmaceutique.
