Recyclable packaging container for dry based powders, grains, particulates and aggregates

Abstract

A recyclable bag for dry based powders, grains, particulates or aggregates having a minimum single ply of high-density porous paper adapted to be foldably configure into a sealable bag shape wherein at least one ply of high density porosity paper has an adhered layer of a hydrophobic biodegradable material on an external and/or internal side wherein the adhered layer of hydrophobic biodegradable material includes a series of holes, spacing and/or slots within or around the hydrophobic biodegradable material to allow air to pass there through for aeration of the bag during filling of the bag.

1 . A recyclable bag for dry particulates such as grains, powders or aggregates, the bag including at least one ply of high-density porous paper foldable into a closable bag shape to provide a paper-based receptacle, wherein:
 a. at least one of the plies has an adhered layer of a hydrophobic biodegradable material on a face thereof, the layer being defined in areas spaced about the face,   b. the spaces between the areas are configured to allow air to escape through the face within the spaces, whereby air may escape from the spaces during filling of the bag with powders, grains, particulates or aggregates.   
     
     
         2 . The recyclable bag of  claim 1  wherein the hydrophobic biodegradable material is a polymer. 
     
     
         3 . The recyclable bag of  claim 2  wherein the hydrophobic biodegradable material is a wax. 
     
     
         4 . The recyclable bag of  claim 1  wherein the face within the spaces has greater permeability to air than the areas on the face having the hydrophobic biodegradable material adhered thereon. 
     
     
         5 . The recyclable bag of  claim 1  wherein the adhered layer is applied to the face of the ply as droplets. 
     
     
         6 . The recyclable bag of  claim 5  wherein the droplets are applied to the face of the ply as a spray. 
     
     
         7 . The recyclable bag of  claim 1  wherein the adhered layer is defined as droplets of the hydrophobic biodegradable material spattered about the face of the ply, wherein spaces which lack the hydrophobic biodegradable material are defined between the spattered droplets. 
     
     
         8 . The recyclable bag of  claim 7  wherein the spaces lacking the hydrophobic biodegradable material occupy more of the area of the face of the ply than the spattered droplets. 
     
     
         9 . The recyclable bag of  claim 1  wherein the areas of hydrophobic biodegradable material are defined by spraying the hydrophobic biodegradable material about the face, whereby one of:
 a. the material-bearing areas, and 
 b. the spaces between the material-bearing areas, 
 is finely dispersed within the other at a frequency of several per square centimeter. 
 
     
     
         10 . The recyclable bag of  claim 1  having outer and inner plies of high-density porous paper having adjacent faces, wherein the hydrophobic biodegradable material is adhered to at least one of the adjacent faces. 
     
     
         11 . The recyclable bag of  claim 1  having outer and inner plies of high-density porous paper, wherein the hydrophobic biodegradable material is adhered to an external face of the inner ply. 
     
     
         12 . The recyclable bag of  claim 1  wherein the hydrophobic biodegradable material has a color different from that of the face of the ply upon which the hydrophobic biodegradable material is adhered. 
     
     
         13 . The recyclable bag of  claim 1  wherein the hydrophobic biodegradable material is adhered to an external face of an outermost ply of high-density porous paper in a pattern defining alphanumeric indicia. 
     
     
         14 . The recyclable bag of  claim 1  wherein the hydrophobic biodegradable material is adhered to selected areas on the face of the ply defining one or more of:
 a. the bottom of the bag; 
 b. smaller sides of the bag defined between larger sides of the bag. 
 
     
     
         15 . The recyclable bag of  claim 1  wherein the hydrophobic biodegradable material is adhered to selected areas on the face of the ply defining opposing sides of the bag, with the selected areas being spaced by regions lacking the hydrophobic biodegradable material. 
     
     
         16 . The recyclable bag of  claim 1  wherein the hydrophobic biodegradable material rests atop or beneath at least a major portion of the area of the bag. 
     
     
         17 . The recyclable bag of  claim 1  defining a closed bag having an internal volume, wherein at least a major portion of the internal volume is filled with dry particulates. 
     
     
         18 . A recyclable bag for dry particulates such as grains, powders or aggregates, the bag including a ply of high-density porous paper which:
 a. extends across at least a major portion of at least one side of the bag, and   b. has opposing faces, at least one of the faces bearing hydrophobic biodegradable material defined in areas spaced about the face, wherein the spaces between the material-bearing areas have greater permeability to air than the material-bearing areas.   
     
     
         19 . The recyclable bag of  claim 18  wherein the spaced areas of hydrophobic biodegradable material occur at a frequency of several spaced areas per centimeter across at least a portion of the face. 
     
     
         20 . A recyclable bag for dry particulates such as grains, powders or aggregates, the bag being formed of one or more layers of high-density porous paper, each layer having opposing faces, wherein at least one of the layers has hydrophobic biodegradable material defined on at least one of the faces thereof as spattered droplets of the hydrophobic biodegradable material, wherein spaces which lack the hydrophobic biodegradable material are defined between the spattered droplets.
