The present disclosure relates to a method for producing a high burst slider zipper which allows for bottom filling of reclosable packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing a peel seal or other frangible or separable connection between the zipper profiles, and by sealing a portion of one of the flanges to itself by a hard seal above the peel seal. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces.

1. A method of manufacturing reclosable packages, comprising the steps of: providing first and second package walls, joined together at edges thereof, for the reclosable package;providing a zipper assembly including a first profile and a second profile, wherein the first profile includes a first interlocking element and a first flange, the second profile includes a second interlocking element and a second flange, the zipper assembly further including a segment connecting the first flange to the second flange by a separable connection, wherein the separable connection is more resistant to a shear force than to a peeling force;attaching the second flange to an exterior of the second package wall;after the step of attaching the second flange to the second package wall, filling the reclosable package between the first flange and the first package wall;after the step of filling the reclosable package, attaching the first flange to an exterior of the first package wall. 2. The method of claim 1 wherein the first flange includes a first segment extending from the first interlocking element and a second segment extending from the first segment. 3. The method of claim 2 wherein the second flange extends from a location on the first segment between the first interlocking element and the separable connection. 4. The method of claim 2 wherein the step of attaching the first flange to the first package wall comprises attaching the second segment of the first flange to the first package wall. 5. The method of claim 4 wherein the separable connection is formed between the first segment of the first flange and the second flange. 6. The method of claim 1 wherein the step of attaching the first flange to the first package wall comprises attaching a portion of the first flange, between the first interlocking element and the separable connection, to the first package wall. 7. The method of claim 1 wherein the zipper assembly extends beyond the first and second package walls. 8. A method of manufacturing reclosable packages, comprising the steps of: providing first and second package walls, joined together at edges thereof, for the reclosable package;providing a zipper assembly including a first profile and a second profile, wherein the first profile includes a first interlocking element and a first flange, the second profile includes a second interlocking element and a second flange, the zipper assembly further including an unactivated separable connection formed on one of the first flange and the second flange;attaching the first flange to an exterior of the first package wall;attaching the second flange to an exterior of the second package wall;after the steps of attaching the first flange and attaching the second flange, filling the reclosable package between the first interlocking element and the second interlocking element;after the step of filling, activating the separable connection thereby joining the first flange and the second flange, thereby the separable connection being more resistant to a shear force than to a peel force;after the step of filling, interlocking the first interlocking element with the second interlocking element. 9. The method of claim 8 wherein the first flange includes a first segment extending from the first interlocking element and a second segment extending from the first segment. 10. The method of claim 9 wherein the second flange extends from a location on the first segment between the first interlocking element and the separable connection. 11. The method of claim 9 wherein the step of attaching the first flange to the first package wall comprises attaching the second segment of the first flange to the first package wall. 12. The method of claim 11 wherein the separable connection is formed between the first segment of the first flange and the second flange. 13. The method of claim 8 wherein the step of attaching the first flange to the first package wall comprises attaching a portion of the first flange, between the first interlocking element and the separable connection, to the first package wall. 14. The method of claim 8 wherein the zipper assembly extends beyond the first and second package walls. 15. A method of manufacturing reclosable packages, comprising the steps of: providing first and second package walls, joined together at edges thereof, for the reclosable package;providing a zipper assembly including a first profile and a second profile, wherein the first profile includes a first interlocking element and a first flange, the second profile includes a second interlocking element and a second flange, the zipper assembly further including a segment connecting the first flange to the second flange by a separable connection, wherein the separable connection is more resistant to a shear force than to a peeling force;attaching the second flange to an exterior of the second package wall;after the step of attaching the second flange to the second package wall, filling the reclosable package from a location below at least a portion of the first flange, and adjacent the separable connection; andattaching the first flange to an exterior of the first package wall. 16. The method of claim 15 wherein the first flange includes a first segment extending from the first interlocking element and a second segment extending from the first segment. 17. The method of claim 16 wherein the second flange extends from a location on the first segment between the first interlocking element and the separable connection. 18. The method of claim 16 wherein the step of attaching the first flange to the first package wall comprises attaching the second segment of the first flange to the first package wall. 19. The method of claim 18 wherein the separable connection is formed between the first segment of the first flange and the second flange. 20. The method of claim 15 wherein the step of attaching the first flange to the first package wall comprises attaching a portion of the first flange, between the first interlocking element and the separable connection, to the first package wall. 21. The method of claim 15 wherein the zipper assembly extends beyond the first and second package walls.
