A water-soluble substrate, and more particularly a water-soluble substrat e that is resistant to contact with small amounts of water, and methods of m aking 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 sub stantially covers at least one surface of the water-soluble substrate. The w eight ratio of coating to water-soluble substrate is higher than 0.8. Articl es, such as pouches, made from the water-soluble substrate, are also disclos ed herein. |
