Abstract: A multi-layered bag with a re-sealable closure assembly attached thereto is provided, as well as a method of manufacturing the same. Specifically, multi-layered paper composite bags with a re-sealable closure assembly attached to the innermost layer of the bag as well as a method of manufacturing the same are provided. A slider-operated zipper is a particularly preferred embodiment of a re-sealable closure assembly. The bags may be gusseted and comprise an outer paper layer, a middle paper layer and an inner plastic film or sheet layer, and the bottom of the bag may be open bottomed or close bottomed.
