Packages with active agents are described. Generally, the disclosed packages have a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides so as to define a mouth opposite the bottom, a reclosable fastener extending along the mouth, and an active agent. The reclosable fastener includes a pair of polymeric tracks, in which each of the tracks includes a mating element and a fin portion. The mating elements are releasably engageable to each other, and each of the fin portions extends downwards from the respective mating element towards the bottom of the reclosable package. The active agent is associated with at least one of the fin portions for communication with the interior of the reclosable package.

What is claimed is: 1. A reclosable package comprising: a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides, the body panels defining a mouth opposite the bottom; a reclosable fastener extending along the mouth and including a pair of polymeric tracks, each of the tracks including a mating element and a fin portion, the mating elements being releasably engageable to each other, each of the fin portions extending generally downwardly from the reclosable element towards the bottom of the reclosable package; and an antimicrobial extruded or impregnated in at least one of the fin portions for release in a gaseous form into an interior of the reclosable package. 2. The reclosable package of claim 1, wherein the antimicrobial is extruded with the at least one of the fin portions. 3. The reclosable package of claim 2, wherein the antimicrobial is distributed in the form of microcapsules in the at least one of the fin portions. 4. The reclosable package of claim 1, further comprising: a means for selectively initiating release of the antimicrobial. 5. The reclosable package of claim 1, wherein the antimicrobial is activated by humidity. 6. The reclosable package of claim 1, further comprising: a one-time breakable element extending between the fin portions and disposed between the interior and the reclosable fastener. 7. The reclosable package of claim 6, wherein the antimicrobial is disposed above the one-time breakable element. 8. The reclosable package of claim 6, wherein the antimicrobial is disposed below the one-time breakable element. 9. The reclosable package of claim 1, further comprising: a barrier layer associated with at least one of the body panels to define a barrier environment for the interior. 10. The reclosable package of claim 1, wherein the antimicrobial is included in an antimicrobial layer, the reclosable package further comprising: a barrier layer associated with the at least one of the fin portions. 11. The reclosable package of claim 10, wherein the antimicrobial layer is located closer to the interior than the barrier layer. 12. The reclosable package of claim 1, further comprising: a diffusion layer associated with the at least one of the fin portions, the diffusion layer being adjacent to an antimicrobial layer including the antimicrobial. 13. The reclosable package of claim 12, wherein the diffusion layer is located closer to the interior than the antimicrobial layer. 14. The reclosable package of claim 1, wherein the antimicrobial is selected from the group consisting of carbon dioxide, diacetyl, chlorine dioxide, allyl isothiocyanate (AIT), ethyl alcohol, carvacrol, cinnamic aldehyde, methyl j asmonate, and mixtures thereof. 15. A reclosable package comprising: a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides, the body panels defining a mouth opposite the bottom; a reclosable fastener extending along the mouth and including a pair of polymeric tracks, each of the tracks including a mating element and a fin portion, the mating elements being releasably engageable to each other, each of the fin portions extending generally downwardly from the reclosable element towards the bottom of the reclosable package; an antimicrobial agent extruded or impregnated in at least one of the fin portions for release in a gaseous form into an interior of the reclosable package; and wherein the antimicrobial agent includes an isothiocyanate compound. 16. The reclosable package of claim 15, wherein the antimicrobial agent further includes an acid. 17. The reclosable package of claim 15, wherein the antimicrobial agent further includes a fragrant. 18. A reclosable package comprising: a first opposing body panel having an inner surface and an outer surface; a second opposing body panel having an inner surface and an outer surface, the first and second body panels being joined along a pair of opposing sides and a bottom bridging the sides so as to form an open mouth at one end, the joined first and second body panels forming an interior space; and a reclosable polymeric seal extending along the one end of the respective inner surfaces of the first and second opposing body panels, the reclosable polymeric seal including a first polymeric track and a second polymeric track, the first polymeric track including a first fin portion and a first mating element, the first fin portion extending generally downwardly from the first reclosable element toward the bottom, the first fin portion having at least a first layer having an antimicrobial extruded or impregnated therein for release in a gaseous form into an interior of the reclosable package and a second layer being a barrier layer, the second polymeric track including a second fin portion and a second mating element, the second fin portion extending generally downwardly from the second reclosable element toward the bottom, the second fin portion having at least a third layer having an antimicrobial extruded or impregnated therein for release in a gaseous form into an interior of the reclosable package and a fourth layer being a barrier layer, the first mating element and the second mating element being releasably engageable to each other. 19. The reclosable package of claim 18, wherein the antimicrobial is selected from the group consisting of carbon dioxide, diacetyl, chlorine dioxide, allyl isothiocyanate (AIT), ethyl alcohol, carvacrol, cinnamic aldehyde, methyl jasmonate, and mixtures thereof.
