Repositionable lidding film- seal activated

Abstract

The present document describes a package for distributing and storing produce comprising: a container for holding produce, the container comprising a peripheral edge defining an opening into the container; a film for being positioned onto the peripheral edge of the container to close the opening; and an adhesive material for providing an airtight seal between the film and the peripheral edge upon being activated once the film has been positioned to cover the opening; and wherein upon being activated, the adhesive material populates both the peripheral edge and the film, the film thereby being repositionable onto the peripheral edge to reclose the opening of the container once the airtight seal has been broken upon initial opening of the package.

1 . A package for distributing and storing produce comprising:
 a container for holding produce, the container comprising a peripheral edge defining an opening into the container;   a film for being positioned onto the peripheral edge of the container to close the opening; and   an adhesive material for providing an airtight seal between the film and the peripheral edge upon being activated once the film has been positioned to cover the opening; and   wherein upon being activated, the adhesive material populates both the peripheral edge and the film, the film thereby being repositionable onto the peripheral edge to reclose the opening of the container once the airtight seal has been broken upon initial opening of the package.   
     
     
         2 . The package of  claim 1 , wherein the peripheral edge of the container comprises the adhesive material to be activated. 
     
     
         3 . The package of  claim 1 , wherein the adhesive material is for being activated via at least one of heat and radiation being applied thereto. 
     
     
         4 . The package of  claim 1 , wherein the film comprises micro-perforations practiced there through for controllably transferring a gaseous substance into or out of the container, through the film, and according to a respiration rate of the produce. 
     
     
         5 . The package of  claim 4 , wherein the micro-perforations each comprise a diameter from about 30 to about 60 microns. 
     
     
         6 . The package of  claim 1 , wherein the film comprises at least one of a polymer-based film, a layer of translucent plastic, a layer of paper-based material a cellulose-based film, and a corn-based film. 
     
     
         7 . The package of  claim 1 , wherein the container comprises one of: a tub-like container; a box-like container; a can-like container; and a tray. 
     
     
         8 . The package of  claim 1 , wherein the container is made of a clear rigid plastic material. 
     
     
         9 . The package of  claim 1 , wherein the film comprises an additive for altering an interior environment composition, to impact on at least one of: the produce; and an overall visual aspect associated with the package. 
     
     
         10 . The package of  claim 1 , wherein the film comprises a thickness from about 25 to about 175 microns. 
     
     
         11 . The package of  claim 1 , wherein at least one of the film and the container comprises at least one of an opening indicator and a tamper evident indicator, thereby respectively providing for a breaking of the airtight seal upon the initial opening of the package and an indication of the package having been opened. 
     
     
         12 . The package of  claim 1 , comprising a non-breakable sealant over a portion of the peripheral edge, for preventing a complete peeling of the film away from the peripheral edge upon the initial opening of the package. 
     
     
         13 . A lidding film for installation over a peripheral edge of a container to be loaded with produce, to form a package, the lidding film comprising:
 a film for being positioned onto the peripheral edge, to close the container once loaded with the produce and to form an airtight seal with the peripheral edge upon an activation of an adhesive material, the adhesive material being provided between the film and the peripheral edge; and   wherein the activation of the adhesive material populates both the peripheral edge and the film, the film thereby being repositionable onto the peripheral edge to allow the container to be reclosed once the airtight seal has been broken upon the package being initially opened.   
     
     
         14 . The lidding film of  claim 13 , wherein the film comprises micro-perforations practiced there through, the micro-perforations for controllably transferring a gaseous substance into or out of the package upon the airtight seal being formed, the controllably transferring being according to a respiration rate of the produce. 
     
     
         15 . The lidding film of  claim 14 , wherein the micro-perforations have a diameter from about 30 to about 150 microns. 
     
     
         16 . The lidding film of  claim 14 , wherein the diameter is from about 30 to about 90 microns. 
     
     
         17 . The lidding film of  claim 14 , wherein the diameter is from about 30 to about 60 microns. 
     
     
         18 . The lidding film of  claim 14 , wherein the micro-perforations are uniformly distributed over at least a portion of the film. 
     
     
         19 . The lidding film of  claim 13 , wherein the film comprises at least one of a polymer-based film, a layer of translucent plastic, a layer of paper-based material a cellulose-based film, and a corn-based film. 
     
     
         20 . The lidding film of  claim 13 , wherein the film comprises an additive, the additive comprising at least one of: an ethylene absorption agent for slowing a ripening rate of the produce to be packaged; and an anti-fog agent for improving a translucence of the package.
