Abstract: A storage bag comprises: first and second panels joined or connected on three sides and having a mouth on a fourth side; a pair of zipper strips respectively joined to the first and second panels in the region of the mouth, each zipper strip comprising respective upper and lower zipper profiles; resealable means joined to at least one of the zipper strips in a region between the upper and lower zipper profiles; and a slider that pushes the respective pairs of zipper profiles together and reseals the resealable means as the slider travels along the mouth of the bag. In one embodiment, the resealable means comprise a layer of adhesive material that adheres to the base web of the opposing zipper strip as the moving slider presses the adhesive material and base web together. In another embodiment, the resealable means comprise first and second layers of cohesive material that cohere to each other as the moving slider presses the layers of cohesive material together.

Abstract: A plastic zipper for use in a reclosable package or bag. The zipper includes a pair of fastener strips respectively having male and female interlockable members formed thereon. The male member has a profile with an expanded head. The female member has a profile with a groove for receiving the expanded head of the male member. The female member preferably includes a base, first and second walls extending from the base, first and second hooks respectively extending from the first and second walls toward a center plane of the female member, and first and second wings respectively extending from the first and second walls away from the center plane. The wings have surfaces for guiding an impinging male member toward an opening defined by the hooks of the female member. Preferably, the plastic zipper has a target width to zipper height ratio substantially equal to or greater than unity.
