Abstract
A self-adhesive label has discrete areas having differently patterned adhesive coverages. Thus, areas where permanent adhesion is desired have full or 100% coverage of a permanent adhesive whereas areas where lesser adhesion is desired have fine patterns with lesser percentages of coverage, such as 30% coverage of the same adhesive which would permit a resealable mode of operation. This type of label could be applied from backing tape to a cereal box, or a bag for example, to control operation of a dispensing flap or spout. A label may have full coverage of a permanent pressure-sensitive adhesive at one end, an area of fine adhesive pattern coverage for resealing, and an adhesive-free lift tab at the remote end. The fine pattern may include lines of adhesive extending in the direction of peeling, to provide uniform resistance.
