A flexible package that includes a flexible material in the form of a first panel and a second panel. The first panel includes a first perimeter that is attached to a second perimeter, associated with the second panel, to form an interior cavity, between the first panel and second panel, in which content is stored. The package also includes an adhesive that is attached to a first exterior surface of the first panel or a second exterior surface of the second panel. The adhesive has a first state that prevents the adhesive from bonding with the flexible material that does not permit the package, once opened, to be reclosed. The adhesive may have a second state that can be activated to enable the adhesive to bond with the flexible material that permits the package, once opened, to be reclosed or resealed.

1. A flexible package comprising: a first panel and a second panel that are formed by a flexible material, the first panel being attached to the second panel to form an interior cavity, between the first panel and second panel, in which content is stored; andan activatable adhesive that is located on an exterior surface of the first panel or the second panel, the adhesive having an inactive state and an active state, wherein the inactive state precludes the adhesive from bonding with a separate portion of the first or second panel,wherein the active state is achieved by roughening, rubbing, heating, or scraping the adhesive and, when activated, enables the adhesive to bond with a separate portion of the first or second panel; anda seal between the first panel and the second panel which defines an openable access point for the package,wherein the activatable adhesive is disposed on an exterior of the first panel in the location of the seal, andwherein when the package is in a resealed position, the activated adhesive is releasably bonded to an interior surface of the second panel. 2. The flexible package of claim 1, where the adhesive comprises a pressure sensitive adhesive or a cohesive. 3. The flexible package of claim 2 wherein the adhesive is a cohesive, the flexible package comprises a plurality of locations of cohesive, and the locations of the cohesives are disposed to enable the cohesives to bond with each other. 4. The flexible package of claim 1, where the flexible material corresponds to a monoweb polymer. 5. The flexible package of claim 1, where the flexible material corresponds to a multiweb polymer. 6. The flexible package of claim 1 comprising a plurality of locations of activatable adhesive. 7. A method of resealing the flexible package of claim 1, the method comprising: opening the seal of the flexible package to access content stored within the flexible package;causing the adhesive disposed on the exterior of the first panel to change from the inactive state to an active state by roughening, rubbing, heating, or scraping the adhesive; andcausing the adhesive, in the active state, to bond to an interior surface of the second panel to close the flexible package. 8. The method of claim 7, where heating the adhesive includes causing a temperature of the adhesive to increase to a threshold associated with the glass transition temperature of the adhesive.
