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 high-strength, oriented synthetic plastic film whose opposing surfaces are corona-discharge treated to render them wettable and receptive to adhesives, and a paper face ply adhesively laminated to the base ply. The exposed surface of the base plastic-film ply is coated with a water-remoistenable adhesive, so that when this adhesive is moistened in a tape dispenser, the sealing tape can then be adhered to the carton. Since the remoistenable adhesive is coated on the plastic 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 relatively long "open-time" period. By reason of the strong bond between the plastic film ply and the paper face ply which resists delamination, the tape adhered to the carton may be stripped in toto therefrom, so that the carton may then be recycled.
