Abstract
A gusseted bag of disposable packaging material has a roll-top closure comprising two releasably engageable fastener components. Each fastener component comprises a plastic base layer carrying either hook or loop elements. In some cases, one component is secured to one face of a rollable top of the bag, and the other component is carried on a flexible flap secured to a lower portion of an opposite face of the bag. In another embodiment, one fastener component extends in a strip from an upper edge of the bag down one face of the bag, and the other fastener component extends in a strip from an upper edge of the bag down an opposite face, such that when the top of the bag is folded downward, one fastener component will engage the other fastener component to hold the top closed.
