2. The flexible packaging of claim 1 , wherein the film layer is scored to form at least one resealable flap continuous with the at least one pull tab.

3. The flexible packaging of claim 2 , wherein the resealable flap may be separated from the base layer and resealed to the base layer, via the pressure sensitive adhesive.

4. The flexible packaging of claim 2 , wherein the pull tab and resealable flap are aligned to be lifted in the machine direction.

5. The flexible packaging of claim 1 , wherein the at least one adhesive-free zone is disposed continuously, in the machine direction, in the approximate center of the film layer.

6. The flexible packaging of claim 5 , wherein at least two cavities are scored in the base layer, each cavity being disposed adjacent to opposite sides of the at least one adhesive-free zone.

7. The flexible packaging of claim 6 , wherein the film layer is scored to form at least two resealable flaps continuous with at least two pull tabs.

8. The flexible packaging of claim 7 , wherein the at least two resealable flaps are resealably affixed, via the pressure sensitive adhesive layer, to a portion of the substrate base layer defining the at least two cavities.

9. The flexible packaging of claim 6 , wherein the at least one continuous adhesive-free zone is disposed between the two cavities and has a width which is less than the distance between the two cavities.

10. The flexible packaging of claim 1 , wherein the at least one adhesive-free zone is disposed continuously, in the machine direction, left or right of center of the film layer.

11. The flexible packaging of claim 10 , wherein the film layer is scored to form at least one resealable flap which is continuous with the at least one pull tab, and wherein both the pull tab and resealable flap are aligned to be lifted in a direction which is approximately perpendicular to the machine direction.

12. The flexible packaging of claim 1 , additionally comprising tamper-evident indicators.

13. A flexible packaging comprising:

a substrate base layer; and

a film layer at least partially releasably affixed to the substrate base layer via a pressure sensitive adhesive layer, the pressure sensitive adhesive layer comprising:

at least one adhesive zone, and

at least one adhesive-free zone, wherein the at least one adhesive-free zone extends along an entire length of the packaging, continuously in a machine direction, and wherein at least one adhesive-free zone is disposed in the center of the film layer;

wherein the film layer is scored to form a pull tab which is disposed within the at least one adhesive-free zone, and wherein the pull tab is scored down its center, such that it can be separated into two pull tabs;

wherein the film layer is additionally scored to form two resealable flaps which are continuous with each of the two pull tabs; and

wherein the substrate base layer is scored to form two cavities which are disposed on opposite sides of the at least one adhesive-free zone and are aligned with the two resealable flaps.

14. The flexible packaging of claim 13 , wherein the at least one adhesive zone is disposed such that it releaseably affixes the resealable flaps to a portion of the substrate base layer defining the two cavities.

15. A method for forming a flexible packaging comprising:

providing a substrate base layer;

providing a film layer;

laminating the substrate base layer to the film layer using a pressure sensitive adhesive, wherein the pressure sensitive adhesive is disposed such that it creates an adhesive zone and at least one adhesive-free zone between the base layer and the film layer, and wherein the at least one adhesive-free zone extends along an entire length of the packaging, continuously in a machine direction, in a lane having continuously parallel edges;

scoring the film layer to form at least one pull tab within the adhesive-free zone and at least one resealable flap which is continuous with the at least one pull tab; and

scoring the base layer to form at least one cavity which is aligned with the resealable flap.

16. The method of claim 15 , wherein a die cutting machine is utilized to score the film and base layer.

17. The method of claim 15 , wherein a laser is utilized to score the film and base layer.

18. The method of claim 15 , wherein the adhesive zone is pattern applied to avoid the adhesive-free zone.

19. The method of claim 15 , wherein the pressure sensitive adhesive is disposed throughout the base layer and film layer and wherein the pressure sensitive adhesive is partially deactivated, continuously in the machine direction, to create the adhesive-free zone.

20. A film laminate comprising a plurality of flexible packaging structures comprising:

a substrate base layer; and

a film layer at least partially releasably affixed to the substrate base layer via a pressure sensitive adhesive layer, the pressure sensitive adhesive layer comprising:

at least one adhesive zone, and

at least one adhesive-free zone, wherein the at least one adhesive-free zone extends in a continuous lane having parallel edges, in a machine direction, through an entire length of the plurality of packaging structures;

wherein the film layer is scored to form at least one pull tab, in each of the plurality of packaging structures, which is disposed within the at least one adhesive-free zone; and

wherein the substrate base layer is scored to form at least one cavity which is disposed adjacent the at least one adhesive-free zone.

21. A flexible packaging comprising:

a substrate base layer; and

a film layer at least partially releasably affixed to the substrate base layer via a pressure sensitive adhesive layer, the pressure sensitive adhesive layer comprising:

at least one adhesive zone, and

at least one adhesive-free zone, wherein the at least one adhesive-free zone extends continuously in a machine direction, in the approximate center of the film layer, in a lane having continuously parallel edges;

wherein the film layer is scored to form at least one pull tab which is disposed within the at least one adhesive-free zone;

wherein the substrate base layer is scored to form at least two cavities, each cavity being disposed adjacent to opposite sides of the at least one adhesive-free zone; and

wherein the at least one continuous adhesive-free zone is disposed between the two cavities and has a width which is less than the distance between the two cavities.
