ABSTRACT:
A method of making sealing tape by (i) applying a thin coating of liquid adhesive onto one side of a moving thin film continuous web; (ii) contacting the liquid adhesive coating applied to the web with the surface of a rotating roller, the speed of the roller at the area of contact with the moving adhesive coating being different from the speed of the moving web, to effect roughening of the surface of the applied adhesive coating into a surface texture having a random pattern; and (iii) drying or curing the textured adhesive coating on the web to produce a dry coating of adhesive with a roughened surface texture having peaks and valleys. An economy sealing tape is also disclosed, being a plastic thin film substrate with a thin dry coating of a pressure-sensitive adhesive, the surface of the adhesive coating having a nonembossed, roughened surface texture with peaks and valleys and having a coating thickness of less than about 1 mil (0.025 mm) and, further, the tape having at least one adhesive-free zone running in a longitudinal direction wherein the adhesive-free surface area constitutes at least about 10% to about 80% of the total adhesive coated side.
