Abstract:
An economy sealing tape comprising a continuous length of a smooth surfaced plastic thin film substrate having one side carrying a thin dry coating of a pressure-sensitive adhesive, the adhesive coating having on an outer surface, opposite from the one side of the plastic thin film substrate, a nonembossed, roughened surface texture with a plurality of peaks and valleys, each of the peaks having an apex, the adhesive coating having a coating thickness, measured perpendicularly from the one side of the plastic thin film substrate to the peaks' apexes, that is less than about 1 mil (0.025 mm), the one side of the plastic thin film substrate having at least one adhesive-free zone running in a longitudinal direction on the plastic thin film substrate wherein the at least one adhesive-free zone has a surface area of at least about 10% to about 80% of the total surface area of the one side of the plastic thin film substrate.
