Abstract
A zipper assembly for a reclosable flexible package includes a first profile and a second profile. The first profile includes at least a first interlocking element, and the second profile includes at least a second interlocking element. The second interlocking element is complementary to the first interlocking element and selectively couples to the first interlocking element to close the zipper assembly. A composition of at least the first profile includes a hydro-soluble resin and a sealant resin. The hydro-soluble resin includes polyvinyl alcohol (PVOH), and the sealant resin includes polyethylene (PE).

A zipper assembly for a reclosable flexible package, the zipper assembly comprising:
- a first profile that includes at least a first interlocking element;
- and
- a second profile that includes at least a second interlocking element, wherein the second interlocking element is complementary to the first interlocking element and is configured to selectively couple to the first interlocking element to close the zipper assembly,
- wherein a composition of at least the first profile comprises a hydro-soluble resin and a sealant resin, wherein the hydro-soluble resin comprises polyvinyl alcohol (PVOH) and the sealant resin comprises polyethylene (PE).
A method of forming a zipper assembly for a reclosable flexible package, the method comprising:
- producing a first profile that includes at least a first interlocking element;
- and
- producing a second profile that includes at least a second interlocking element, wherein the second interlocking element is complementary to the first interlocking element and is configured to selectively couple to the first interlocking element to close the zipper assembly,
- wherein at least one of producing the first profile or producing the second profile includes forming a composition that comprises a hydro-soluble resin and a sealant resin, wherein the hydro-soluble resin comprises polyvinyl alcohol (PVOH) and the sealant resin comprises polyethylene (PE).
A zipper assembly for a reclosable flexible package, the zipper assembly comprising:
- a first profile that includes at least a first interlocking element;
- and
- a second profile that includes at least a second interlocking element, wherein the second interlocking element is complementary to the first interlocking element and is configured to selectively couple to the first interlocking element to close the zipper assembly,
- wherein a composition of at least the first profile comprises a hydro-soluble resin having a calcium carbonate filler and a sealant resin, wherein the hydro-soluble resin comprises polyvinyl alcohol (PVOH) and the sealant resin comprises polyethylene (PE)..
