A water-soluble substrate, and more particularly a water-soluble substrate that is resistant to dissolution, and methods of making the same are disclosed. The water-soluble substrate has a first and second surface. Water-insoluble particles are applied to and partially embedded in at least one of said first and second surfaces, thereby forming protruberances on said first and/or second surface. The protruberances have an average height of from 10 nanometer to 100 micrometer, and the average distance between adjacent peaks of said protruberances is from 10 nanometer to 200 micrometer. Articles, such as pouches, made from the water-soluble substrate, are also disclosed herein.
L'invention concerne un substrat soluble dans l'eau et, plus particulièrement, un substrat soluble dans l'eau résistant à la dissolution, ainsi que des procédés de fabrication de celui-ci. Le substrat soluble dans l'eau présente une première et une seconde surface. Des particules insolubles dans l'eau sont appliquées et partiellement intégrées dans au moins une desdites première et seconde surfaces, formant des protubérances sur ladite première et/ou seconde surface. Les protubérances présentent un poids moyen de 10 nanomètres à 100 micromètres, et la distance moyenne entre des pointes adjacentes desdites protrubérances varie de 10 nanomètres à 200 micromètres. L'invention concerne également des articles, par exemple des sachets, obtenus à partir du substrat soluble dans l'eau.
