Abstract

The present disclosure relates to a reclosable flexible film package with a flexible film having a folded edge, at least two opposing free edges, and at least a front panel and a back panel. The front and back panels define an interior space. The flexible film package also may have a score in the flexible film of the front panel forming a flap that defines an opening when the flap is moved upward, toward the folded edge and a label extending uninterrupted from edge to edge of the at least two opposing free edges, the label being attached on the film by pressure sensitive adhesive, and extending beyond the score on the front panel to reseal the package opening defined by the flap.

First claim

We claim:

1. A reclosable flexible film package comprising:
a sheet of flexible film forming a front panel and a rear panel with a fold therebetween, opposing free edges of the flexible film being sealed together to form a first side seal, a second side seal, and an end seal such that the front and back panels define an interior space;
a score in the flexible film of the front panel forming a flap that defines an opening when lifted from a remainder of the package and has a separation force for the flap from the film, the score having a first score end and a second score end disposed adjacent the fold such that the opening is disposed adjacent the fold;
a label extending uninterrupted from the first side seal to the second side seal, the label extending over less than an entire surface of the flexible film, the label being attached onto the film by pressure sensitive adhesive that is disposed over an entire surface of the label, and extending beyond the score on the front panel to reseal the package opening defined by the flap and the label extending over the fold onto the back panel, the pressure sensitive adhesive having a peel strength between the film and the label that is greater than the separation force along the score, and the label further having a pull tab configured such that the flap of the flexible film is lifted from the remainder of the package when the pull tab of the label is grasped and pulled away from the remainder of the package; and
wherein the pull tab includes a substrate disposed over the pressure sensitive adhesive of the label and the substrate extending uninterrupted from the first side seal to the second side seal.

2. The package of claim 1 , wherein the first score end is dispose adjacent a first inward edge of the first side seal and the second score end is disposed adjacent a second inward edge of the second side seal.

3. The package of claim 1 , wherein the score includes at least one of: an arcuate line and a perforation.

4. The package of claim 1 , wherein the first and second score ends include a tear-inhibiting feature.

5. The package of claim 1 , wherein the label extends equidistant on the front and back panel from the fold.

6. The package of claim 1 further comprising a midsection of the score between the first and second score ends, the midsection disposed a distance from the fold.

7. The package of claim 1 , wherein the film is a printed overwrap film laminate comprising a reverse printed oriented polypropylene (OPP) clear film bonded to a white OPP package film.

8. The package of claim 7 , wherein the OPP clear film is a gauge in the range of about 90-230 and the white OPP package film is a gauge in the range of about 90-230.

9. The package of claim 7 , wherein the OPP clear film is about 118 gauge and the white OPP package film is about 118 gauge.

10. The package of claim 1 , wherein the label is a bi-axially oriented polypropylene (BOPP) clear film of a gauge in the range of about 160 to 240.

11. The package of claim 1 , wherein the flexible film is a BOPP clear film of a gauge of about 200.

12. A reclosable package comprising:
a first substrate forming a front panel and a back panel having a first side seal, a second side seal, and an end seal to form an interior cavity for receiving items;
a flap defined by a line of weakness in at least a first panel that defines an opening to the interior cavity when the first panel is separated at the line of weakness;
a second substrate adhered to the first substrate via a pressure sensitive adhesive continuously disposed on the second substrate and the second substrate extending over less than an entire surface of the first substrate, the second substrate having a first portion extending beyond the line of weakness to form a package reseal zone, and a second portion extending from a portion of the first panel to a portion of the second panel and wherein the second substrate extends uninterrupted from the first side seal to the second side seal; and
a third substrate disposed over the pressure sensitive adhesive to form a pull tab, the third substrate extending from the first side seal to the second side seal.

13. The package of claim 12 , wherein the line of weakness is a perforation.

14. The package of claim 12 , wherein the first substrate is a printed overwrap film laminate comprising a reverse printed oriented polypropylene (OPP) clear film bonded to a white OPP package film.

15. The package of claim 14 , wherein the OPP clear film is a gauge in the range of about 48-230 and the white OPP package film is a gauge in the range of about 48-230.

16. The package of claim 14 , wherein the OPP clear film is about 118 gauge and the white OPP package film is about 118 gauge.

17. The package of claim 12 , wherein the second substrate is a bi-axially oriented polypropylene (BOPP) clear film of a gauge in the range of about 160 to 240.

18. The package of claim 12 , wherein the first substrate is a BOPP clear film of a gauge of about 200.

19. The package of claim 12 , wherein the line of weakness includes a first end and a second end disposed adjacent a package fold and the first end is disposed adjacent a first inward edge of the peripheral seal and the second end is disposed adjacent a second inward edge of the peripheral seal.

20. The package of claim 12 wherein the first and second ends of the line of weakness include a tear-inhibiting feature.

21. A reclosable package comprising:
a multi-layer laminate film, the laminate film having at least a sealant layer, a barrier layer, an adhesive layer, and a stiffening layer, the laminate film having a fold therein and forming a front panel and a back panel with a first side seal, a second side seal, and an end seal formed therein to form an interior cavity;
a line of weakness formed in the multi-layer laminate film, the line of weakness defining at least in part a package opening, the line of weakness having first and second ends disposed adjacent the fold such that the package opening is subsequently disposed adjacent the fold;
a closure layer attached to the multi-layer laminate film with an adhesive disposed on an entire surface thereof and extending over the line of weakness, the closure layer extending from a first package edge to a second package edge and over less than an entire surface of the laminate film; and
a substrate disposed over a portion of the adhesive of the closure layer, the substrate forming a pull tab with the closure layer, the substrate extending uninterrupted from the first side seal to the second side seal.

22. The reclosable package of claim 21 wherein the laminate film further comprises a polyester layer and an additional adhesive layer.

23. The reclosable package of claim 21 wherein the laminate film further comprises a release layer.

24. The reclosable package of claim 21 wherein the stiffening layer comprises a fiber substrate.

25. The package of claim 21 wherein the line of weakness further includes a tear-inhibiting feature.

26. The package of claim 21 wherein the first end is disposed adjacent a first inward edge of the peripheral seal and the second end is disposed adjacent a second inward edge of the peripheral seal.
