An adhesive composition is provided that is water-insoluble yet water-absorbent, i.e., capable of absorbing up to 15 wt. % water or more. The composition in composed of a film-forming hydrophilic polymer with at least one linear segment having a plurality of recurring polar groups along the polymer backbone, a complementary multifunctional polymer with a plurality of recurring functional groups that noncovalently bind to the polar groups on the film-forming polymer, and plasticizer. A method for manufacturing the adhesive composition is provided as well.
