Flexible packaging with internal release

1. A blank for forming a package comprising:

a panel defining a first end, a second end opposite the first end, and at least two side edges, wherein the panel comprises:

at least one film layer;

an adhesive adjacent the film layer, wherein the adhesive is pattern applied within an interior region of the film layer and wherein a perimeter of the film layer is adhesive free adjacent each of the first end, second end, and side edges;

a release liner comprising a substrate layer and a cured silicone layer,

wherein the release liner is adhered to the film layer via the adhesive,

wherein the substrate layer of the release liner is disposed adjacent the film layer, and

wherein a perimeter of the release liner is smaller than the perimeter of the film layer.

2. The blank of claim 1 wherein the at least one film layer comprises an outer layer adhered to a printable sealant.

3. The blank of claim 2 wherein the outer layer and printable sealant are coextruded.

4. The blank of claim 2 wherein the outer layer comprises biaxially oriented nylon.

5. The blank of claim 2 wherein the printable sealant is print receptive.

6. The blank of claim 2 wherein the printable sealant comprises polyethylene.

7. The blank of claim 2 wherein the printable sealant is coextensive with the outer layer.

8. The blank of claim 1 wherein the area between the perimeter of the film layer and the perimeter of the release liner comprises a seal area for forming a package.

9. The blank of claim 1 wherein the perimeter of the release liner is substantially aligned with an outer perimeter of the adhesive.

10. The blank of claim 1 wherein the substrate layer comprises polyethylene terephthalate.

11. A package for reactive materials comprising:

a panel defining a first end, a second end opposite the first end, and at least two side edges, wherein the panel comprises:

at least one film layer;

an adhesive adjacent the film layer, wherein the adhesive is pattern applied such that it is disposed within an interior region of the film layer and wherein a perimeter of the film layer is adhesive-free adjacent each of the first end, second end, and side edges;

a release liner comprising a substrate layer and a cured silicone layer,

wherein the release liner is adhered to the film layer via the adhesive,

wherein the substrate layer of the release liner is disposed adjacent the film layer,

wherein a perimeter of the release liner is smaller than the perimeter of the film structure,

wherein the panel comprises a tubular body, and

wherein the side edges are sealed together to form a fin seal, the first end is sealed closed to form an end seal, and the second end is sealed closed to form an end seal.

12. The package of claim 11 wherein the at least one film layer comprises an outer layer adhered to a printable sealant.

13. The package of claim 12 wherein the outer layer and printable sealant are coextruded.

14. The package of claim 12 wherein the outer layer comprises biaxially oriented nylon.

15. The package of claim 12 wherein the printable sealant is print receptive.

16. The package of claim 12 wherein the printable sealant comprises polyethylene.

17. The package of claim 12 wherein the printable sealant is coextensive with the outer layer.

18. The package of claim 11 wherein the substrate layer comprises polyethylene terephthalate.

19. The package of claim 11 wherein the package contains one or more reactive materials.

20. The package of claim 11 wherein the area between the perimeter of the at least one film layer and the perimeter of the release liner comprises the fin seal and end seals.

21. The package of claim 11 wherein the fin seal and end seals are adhesive-free.
