A water-soluble substrate, and more particularly a water-soluble substrat e that is resistant to dissolution, and methods of making the same are discl osed. The water-soluble substrate has a first and second surface. Water-inso luble particles are applied to and partially embedded in at least one of sai d first and second surfaces, thereby forming protruberances on said first an d/or second surface. The protruberances have an average height of from 10 na nometer to 100 micrometer, and the average distance between adjacent peaks o f said protruberances is from 10 nanometer to 200 micrometer. Articles, such as pouches, made from the water-soluble substrate, are also disclosed herei n. |
