Plastic trash bag with odor control and method of making

Abstract

A plastic trash bag with odor control is formed of a bag having a pair of opposed sides joined together along longitudinal edges and at one end, the bag being longitudinally folded such that one bag side defines a pair of adjacent facing surfaces. A generally uniform dusting of odor-absorbing particles is disposed on at least the adjacent facing surfaces.

I claim:  
     
         1 . A plastic trash bag comprising: 
 (A) a bag having a pair of opposed sides joined together along longitudinal edges and at one end, said bag being longitudinally folded such that one bag side defines a pair of adjacent facing surfaces; and    (B) a generally uniform dusting of odor-absorbing particles on said adjacent facing surfaces.    
     
     
         2 . The bag of  claim 1  wherein the other bag side is relatively free of said odor-absorbing particles.  
     
     
         3 . The bag of  claim 1  wherein the other bag side defines a pair of oppositely facing surfaces, and a generally uniform dusting of odor-absorbing particles is also disposed on said oppositely facing surfaces.  
     
     
         4 . The bag of  claim 1  wherein said odor-absorbing particles are baking soda (sodium bicarbonate) particles.  
     
     
         5 . The bag of  claim 1  wherein said odor-absorbing particles are baking soda particles mixed with a relatively small quantity of a flow-control additive.  
     
     
         6 . The bag of  claim 1  wherein said bag is polyethylene.  
     
     
         7 . The bag of  claim 1  wherein said bag is polyethylene having a relatively small quantity of odor-absorbing material therein.  
     
     
         8 . A plastic trash bag comprising: 
 (A) a polyethylene bag having a pair of opposed sides joined together along longitudinal edges and at one end, said bag being longitudinally folded such that one bag side defines a pair of adjacent facing surfaces; and    (B) a generally uniform dusting of odor-absorbing baking soda particles on said adjacent facing surfaces, the other bag side being relatively free of said odor-absorbing particles.    
     
     
         9 . A method of making a plastic trash bag in the form of a longitudinally folded flat tubular web sealed at one end, the method including the step of applying, prior to longitudinal folding of the bag, a generally uniform dusting of odor-absorbing particles to one of the bag sides which will define a pair of adjacent facing surfaces after longitudinal folding of the bag.  
     
     
         10 . The method of  claim 9  wherein the uniform dusting is applied immediately prior to longitudinal folding of the bag.  
     
     
         11 . The method of  claim 9  wherein, after application of the uniform dusting, the bag is longitudinally folded and sealed at one end.  
     
     
         12 . The method of  claim 9  wherein the uniform dusting is applied electrostatically.  
     
     
         13 . The method of  claim 9  wherein the uniform dusting is applied to only the one of the bag sides.  
     
     
         14 . The method of  claim 9  wherein the odor-absorbing particles are baking soda (sodium bicarbonate) particles.  
     
     
         15 . The method of  claim 9  wherein the odor-absorbing particles are baking soda particles mixed with a relatively small quantity of a flow-control additive.  
     
     
         16 . The method of  claim 9  wherein the bag is polyethylene.  
     
     
         17 . The method of  claim 9  wherein the bag is polyethylene having a relatively small quantity of odor-absorbing material therein.  
     
     
         18 . A method of making a plastic trash bag in the form of a longitudinally folded flat tubular web of polyethylene sealed at one end, the method including the step of electrostatically applying, immediately prior to longitudinal folding of the bag, a generally uniform dusting of odor-absorbing baking soda particles to only the one of the bag sides which will define a pair of adjacent facing surfaces after longitudinal folding of the bag.  
     
     
         19 . The method of  claim 18  wherein a generally uniform dusting of odor-absorbing particles is applied to exposed surfaces of the bag subsequent to longitudinal folding of the bag.  
     
     
         20 . A wrap comprising a plastic film having on at least one surface thereof a generally uniform dusting of odor-absorbing baking soda particles.  
     
     
         21 . The wrap of  claim 20  wherein said film has said dusting on each surface thereof.  
     
     
         22 . The wrap of  claim 20  wherein said film has said dusting on only one surface thereof.
