Water activated adhesive and paper-plastic tape containing same

A package sealing tape for attachment to an object, which comprises a substrate of a polymeric film having upper and lower surfaces and on at least a portion of the lower surface of the substrate an adhesive composition comprising:

• a first component of a water activated adhesive agent in an amount sufficient to provide adhesive properties to the composition;
• a second component of an adhesion promoter in an amount sufficient for providing initial tack to composition;
• and a third component of a bonding agent comprising a water soluble imine compound in an amount sufficient to provide adhesion to the polymeric film and preferential anchorage of the film to the object, wherein the first, second and third components are different, and said adhesive composition being activated by contact with water for application to the object.
