5 . The recloseable package of claim 1 , wherein said flexible container and said flexible film member are configured such that a portion of said flexible container including said one of said two end lateral seams can be releasably secured between said flexible film member and said flexible container subsequent to opening one of said two lateral end seams.
6 . The recloseable package of claim 1 , wherein at least a portion of said flexible film member between said opposed ends is permanently adhered to at least one of said front side or said back side of said flexible container.
7 . The recloseable package of claim 6 , wherein said flexible film member has a length that extends from a top lateral edge to a permanently adhered bottom portion of said flexible film member of about 1.78 centimeters or greater.
8 . The recloseable package of claim 1 , wherein said flexible film member is disposed onto an upper half of said flexible container, the upper half extending from said one of said two lateral end seams.
9 . The recloseable package of claim 1 , wherein said flexible film member is disposed onto an upper third of said flexible container, the upper third extending from said one of said two lateral end seams.
10 . The recloseable package of claim 1 , wherein said flexible film member is disposed onto an upper quarter of said flexible container, the upper quarter extending from said one of said two lateral end seams.
11 . The recloseable package of claim 1 , wherein said flexible film member is disposed between an upper half and an upper third of said flexible container, the upper half and the upper third extending from said one of said two lateral end seams.
12 . The recloseable package of claim 1 , wherein said flexible film member is disposed at, above or below a fill line for said product.
13 . The recloseable package of claim 1 , wherein said flexible film member is substantially transparent.
14 . The recloseable package of claim 1 , wherein said flexible film member further comprises printing thereon.
15 . The recloseable package of claim 1 , further comprising one or more adhesives disposed onto one or more portions of said flexible film member.
16 . A method of fabricating a recloseable package for containing a product therein, said method comprising:
adhering opposed ends of a flexible film member permanently onto a flexible container body film; and
forming the flexible container body film into a flexible container having a front side and a back side sealed together along at least one longitudinal seam and two lateral end seams, the flexible film member structured and arranged on said flexible container so as to releasably secure one of said two lateral end seams of said flexible container subsequent to opening one of said two lateral end seams.
17 . A method for releasably securing a recloseable package comprising (i) a flexible container having a front side and a back side sealed together along at least one longitudinal seam and two lateral end seams and (ii) a flexible film member having opposed ends permanently adhered to said flexible container to releasably secure between said opposed ends one of said two lateral end seams of said flexible container, said method comprising:
opening said one lateral end seam; and
securing said one lateral end seam of said flexible container between said flexible container and said flexible film member.
18 . A flexible film for forming a recloseable package, said flexible film comprising:
a flexible container body film; and
a flexible film member having opposed ends permanently adhered to said flexible container body film.
19 . The flexible film of claim 18 , wherein said flexible container body film is selected from the group consisting of one or more paper-based materials, polymeric materials, metallized polymeric materials, metallic foils, and combinations thereof.
