Claims
- 1. A dual closure arrangement for use on a pair of separate polymeric bags, the dual closure arrangement comprising:
a first closure arrangement including a first reclosable fastener, a first header portion with an interior convex area and a second header portion with an interior concave area located opposite the interior convex area of the first header portion; and a second closure arrangement including a second reclosable fastener, a third header portion with an interior convex area and a fourth header portion with an interior concave area located opposite the interior convex area of the third header portion, wherein the first header portion is joined to the third header portion such that the first closure arrangement and the second closure arrangement are connected to each other.
- 2. The dual closure arrangement of claim 1, further comprising one or more gripping ridges disposed on both the first header portion and the third header portion, wherein the gripping ridges are positioned between the convex area and the reclosable fastener of each of the first and second closure arrangements.
- 3. The dual closure arrangement of claim 1, wherein the first header portion and the third header portion each include a preferential area of weakness exterior to the convex area.
- 4. The dual closure arrangement of claim 3, wherein said the preferential area of weakness is selected from the group consisting of a perforation, a knife score, a stress line or a laser score.
- 5. The dual closure arrangement of claim 1, wherein the first header portion and the third header portion each contain a preferential area of weakness exterior to the convex area along a line that is parallel to the reclosable fastener.
- 6. The dual closure arrangement of claim 1, further comprising a peel seal disposed between the reclosable fastener of the first closure arrangement and an interior of the bag and a second peel seal disposed between the reclosable fastener of the second closure arrangement and an interior of the bag.
- 7. A method for making a pair of sealed polymeric bags, comprising:
providing a dual profile having a first closure arrangement and a second closure arrangement joined to each other; sealing a first header portion of the first closure arrangement inside a first film, the first header portion having a convex area; sealing a third header portion of the second closure arrangement inside the first film, the third header portion having a convex area; sealing a second header portion of the first closure arrangement inside a second film, the second film the second header portion having a concave area opposite the convex area of the first header portion; sealing a fourth header portion of the second closure arrangement inside the second film, the fourth header portion having a concave area opposite the convex area of the third header portion; and separating the first closure arrangement from the second closure arrangement to define two separate sealed polymeric bags.
- 8. The method of claim 7 wherein the first header portion is connected to the third header portion prior to separation of the first closure arrangement from the second closure arrangement.
- 9. The method of claim 7 wherein each of the first, second, third and fourth header portions contain one or more gripping ridges.
- 10. The method of claim 7 further comprising the step of perforating the first header portion exterior to the convex area and perforating the third header portion exterior to the convex area.
- 11. The method of claim 7, further comprising the step of perforating the second header portion exterior to the concave area and perforating the fourth header portion exterior to the concave area
