Pregummed remoistenable tape having long open time and short tack time

摘要

A pregummed, remoistenable tape having long open time and short tack time which utilizes adhesive formulations using acid hydrolyzed, derivatized waxy maize starch as a component to replace animal glue in remoistenable pregummed tape formulations. Wet tack strength is equal or better than "all-animal glue" adhesives presently used, especially for short open times. In one embodiment, the major ingredient in the adhesive coating of the pregummed tape comprises waxy maize starch which is first acid-hydrolyzed and then copolymerized with acrylamide monomer using a free radical initiator in an aqueous system.
