| مستخلص: | The zipper includes flanges which include an oxygen scavenging polymer. The oxygen scavenging polymer can be a co-extruded layer or blended with other polymers. The oxygen scavenging polymer is activated by ultra-violet light prior to installation by a form fill seal apparatus. This zipper is particularly useful in reducing residual oxygen in the packaging of such food products as cheese and meat, thereby extending the shelf life. |

| Claim: | 1. A zipper for a reclosable package, including: a first profile including a first interlocking element and a first flange, a second profile including a second interlocking element and a second flange, and a strip with a proximal end and terminating in a distal end, including an oxygen scavenging polymer, wherein the proximal end is attached to and extends from at least one of the first and second flanges and wherein the distal end is a free end which is free of attachment to the first and second flanges. |
| Claim: | 2. The zipper of claim 1 further including a slider which joins the first and second interlocking elements to each other when moved in a first direction and which separates the first and second interlocking elements from each other when moved in a second direction. |
| Claim: | 3. The zipper of claim 1 wherein the oxygen scavenging polymer is activated by ultra-violet light prior to installation on a reclosable bag. |
| Claim: | 4. A zipper for a reclosable package, including: a first profile including a first interlocking element and a first flange, a second profile including a second interlocking element and a second flange, and a strip, including an oxygen scavenging polymer, attached to one of the first and second interlocking elements, terminating in a free distal end, and engaged between the first and second interlocking elements. |
| Claim: | 5. The zipper of claim 4 further including a slider which joins the first and second interlocking elements to each other when moved in a first direction and which separates the first and second interlocking elements from each other when moved in a second direction. |
| Claim: | 6. The zipper of claim 4 wherein the oxygen scavenging polymer is activated by ultra-violet light prior to installation on a reclosable package. |
| Claim: | 7. The zipper of claim 1 wherein the zipper is provided on a spool. |
| Claim: | 8. The zipper of claim 3 wherein the zipper is provided on a spool and wherein the oxygen scavenging polymer is activated after the zipper is removed from the spool. |
| Claim: | 9. The zipper of claim 4 wherein the zipper is provided on a spool. |
| Claim: | 10. The zipper of claim 6 wherein the zipper is provided on a spool and wherein the oxygen scavenging polymer is activated after the zipper is removed from the spool. |
