Abstract

A water-soluble substrate, and more particularly a water-soluble substrate that is resistant to contact with small amounts of water, and methods of making the same are disclosed. A coating which is less water-soluble than the water-soluble substrate and in the form of particles, is applied to and substantially covers at least one surface of the water-soluble substrate. The weight ratio of coating to water-soluble substrate is higher than 0.8. Articles, such as pouches, made from the water-soluble substrate, are also disclosed herein.
