ABSTRACT:
The invention disclosed provides a resealable closure system for a non-rigid product bag. The resealable closure system is generally an adhesive strip affixed to a non-rigid product bag which allows the bag to be reclosed a multiple number of times. The resealable closure system has a permanent adhesive on the first surface such that the system can be affixed to a non-rigid product bag and positioned between the top and the bottom of the bag. The second surface of the bag has a controlled peel adhesive disposed thereon. A release liner containing perforations cut essentially perpendicular to the system's length cover the controlled peel adhesive until use. These perforations permit defined segments of the release liner to be removed to expose new areas of adhesive thereby providing fresh securing sites for subsequent closure and sealing of the bag.
