Medical grade adhesive compositions comprising a homogeneous blend of one or more pressure sensitive adhesive materials and one or more natural or synthetic polymers capable of developing elastomeric properties when hydrated such as gluten and long chain polymers of methyl vinyl ether/maleic acid are disclosed. The compositions may also include one or more water soluble hydrocolloid gums and may additionally contain one or more water swellable cohesive strengthening agents.
