Disclosed herein are multilayer water-dispersible articles including a water-dispersible substrate layer having a thickness in a range of about 5 μm to about 10 mm, and a water- dispersible coating layer on the substrate layer, the coating layer having a thickness in a range of about 0.5 to about 250 μm, wherein water-dispersible article has a moisture vapor transmission rate (MVTR) of about 20 g H2O/m2/day or less, such as 10 g H2O/m2/day or less. L'invention concerne des articles multicouches dispersibles dans l'eau comprenant une couche de substrat dispersible dans l'eau ayant une épaisseur dans une plage d'environ 5 µm à environ 10 mm, et une couche de revêtement dispersible dans l'eau sur la couche de substrat, la couche de revêtement ayant une épaisseur dans une plage d'environ 0,5 à environ 250 µm, l'article dispersible dans l'eau ayant un taux de transmission de vapeur d'humidité (MVTR) d'environ 20 g H2O /m2/jour ou moins, tel que 10 g H2O/m2/jour ou moins.
