Pakages with active agents

Abstract

Packages with active agents are described. Generally, each disclosed package has a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides, a reclosable fastener extending along a mouth formed opposite the bottom, and at least one active agent. The at least one active agent is associated with at least one of the body panels and includes a freshness-extension agent to inhibit spoilage of perishable product disposed in the package, an odor management agent to reduce, mask, or neutralize odors from garbage or waste disposed in the package, or another type of agent.

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;    a reclosable fastener extending along a mouth formed opposite the bottom; and    a freshness-extension agent associated with at least one of the body panels for communication with an interior of the reclosable package and to inhibit spoilage of perishable product disposed therein.    
   
   
       2 . The reclosable package of  claim 1 , wherein the freshness-extension agent is included in at least one of a coating, a patch, a pouch, and a tape applied to the at least one of the body panels.  
   
   
       3 . The reclosable package of  claim 1 , wherein the freshness-extension agent is distributed in the at least one of the body panels.  
   
   
       4 . The reclosable package of  claim 3 , wherein the freshness-extension agent is distributed in the at least one of the body panels in the form of microcapsules.  
   
   
       5 . The reclosable package of  claim 1 , further comprising: 
 a structure to selectively initiate release of the freshness-extension agent.    
   
   
       6 . The reclosable package of  claim 1 , wherein the freshness-extension agent is released by humidity.  
   
   
       7 . The reclosable package of  claim 1 , wherein the freshness-extension agent includes an isothiocyanate compound.  
   
   
       8 . The reclosable package of  claim 7 , wherein the freshness-extension agent further includes an acid.  
   
   
       9 . The reclosable package of  claim 7 , wherein the freshness-extension agent further includes a fragrant.  
   
   
       10 . The reclosable package of  claim 1 , wherein the freshness-extension agent is included in a permeable freshness-extension layer having a release agent.  
   
   
       11 . The reclosable package of  claim 1 , wherein the freshness-extension agent is included in a freshness-extension layer, the reclosable package further comprising: 
 a removable cover removably attached to at least a portion of the freshness-extension layer.    
   
   
       12 . The reclosable package of  claim 11 , wherein the freshness-extension layer is secured to one of the body panels and the removable cover is secured to the other of the body panels.  
   
   
       13 . The reclosable package of  claim 1 , further comprising: 
 a barrier layer associated with the at least one of the body panels.    
   
   
       14 . The reclosable package of  claim 13 , wherein the barrier layer is attached to the at least one of the body panels via at least one of an adhesive, a co-extrusion, a heat seal, and a weld.  
   
   
       15 . The reclosable package of  claim 1 , wherein the freshness-extension agent is included in a freshness-extension layer, the reclosable package further comprising: 
 a diffusion layer disposed adjacent to the freshness-extension layer.    
   
   
       16 . The reclosable package of  claim 15 , wherein the diffusion layer is located closer to the interior than the freshness-extension layer.  
   
   
       17 . The reclosable package of  claim 1 , wherein the freshness-extension agent is included in a freshness-extension layer and the at least one of the body panels defines a perforation extending therethrough, the freshness-extension layer being disposed on the exterior of the at least one of the body panels adjacent the perforation.  
   
   
       18 . The reclosable package of  claim 1 , wherein the freshness-extension agent is included in a freshness-extension layer attached to one of the body panels, the freshness-extension layer including a one-time breakable element extending between and secured to the opposing body panels.  
   
   
       19 . 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,    a reclosable polymeric seal extending along the one end of the inner surface of the first and second opposing body panels,    at least one polymeric freshness-extension structure including a first polymeric layer being a barrier layer and a second polymeric layer being a diffusion layer and including a freshness-extension agent, the second polymeric layer being adjacent to the first polymeric layer, the first polymeric layer being attached to the package such that the freshness-extension agent of the second layer is in communication with the interior space.    
   
   
       20 . A freshness-extension structure comprising: 
 a first polymeric layer being a barrier layer,    a second polymeric layer being a diffusion layer and including a freshness-extension ingredient, the second polymeric layer being adjacent to the first polymeric layer, and    a removable cover removably attached to at least a portion of the second polymeric layer.
