ABSTRACT:
A paper-film laminate sealing tape for sealing a corrugated board carton or other article fabricated of recyclable material. The tape is composed of a base ply formed of oriented synthetic plastic film whose opposing surfaces are corona-discharge treated to render them wettable and receptive to adhesives, and a paper face ply cold laminated to the base ply by a water-based adhesive. The exposed surface of the film base ply is coated with a water-remoistenable adhesive, such as a starch, so that when this adhesive is moistened in a tape dispenser, the sealing tape can then be adhered to the carton. Since the re-moistenable adhesive is coated on the film ply which is water-impermeable, when this adhesive is moistened with water it remains in a moistened state in a condition to be applied to the carton for a controlled "open-time" period. Because of the strong bond between the film base ply and the paper face ply which resists delamination, the laminate tape adhered to the carton may be stripped therefrom, so that the carton can then be recycled or reused.
