Wetness indicating roll wrap system, and methods

Abstract

A wetness indicating wrap system that provides evidence to the user if the roll wrap system has been exposed to water or other aqueous material. The wetness indicating wrap system includes a water contact indicator (e.g., soluble dye present as indicia) on an outer surface of the roll wrap system, the water contact indicator configured to bleed, run, or otherwise distort when exposed to water or other aqueous material. The water contact indicator dries in its distorted image, thus providing an indication that the water contact indicator, and thus the roll wrap system, had been exposed to water or other aqueous material.

1 . A wrapped roll of sheet material comprising:
 (a) a roll of sheet material having a first end and an opposite second end; and   (b) a wetness indicating wrap system comprising a roll wrap system at least partially covering the roll, the roll wrap system having a water contact indicator thereon and comprising an outer wrap of material wrapped circumferentially around the roll and an outer header covering at least one end of the roll.   
   
   
       2 . The wrapped roll of  claim 1  wherein each of the outer wrap and the outer header has the water contact indicator thereon. 
   
   
       3 . The wrapped roll of  claim 2  wherein the outer header comprises a first header covering the first end of the roll and a second header covering the second end of the roll. 
   
   
       4 . The wrapped roll of  claim 3 , wherein each of the outer wrap, the first header and the second header has the water contact indicator thereon. 
   
   
       5 . The wrapped roll of claim I wherein the water contact indicator comprises indicia formed from a water soluble dye. 
   
   
       6 . The wrapped roll of  claim 5  wherein the water soluble indicia is alphanumeric. 
   
   
       7 . The wrapped roll of  claim 5  wherein the water soluble indicia comprises a repeating pattern. 
   
   
       8 . The wrapped roll of  claim 1  wherein the sheet material is paper. 
   
   
       9 . A method of monitoring the quality of rolled sheet material, the method comprising:
 wrapping a roll of sheet material with a wetness indicating wrap system comprising a roll wrap system having a water contact indicator thereon; and   monitoring the wrapped roll for distortion of the water contact indicator.   
   
   
       10 . The method of  claim 9  further comprising, after wrapping, storing the wrapped roll. 
   
   
       11 . The method of  claim 9  further comprising, after wrapping, transporting the wrapped roll from a first location to a second location. 
   
   
       12 . The method of  claim 9  wherein wrapping a roll of sheet material with a wetness indicating wrap system comprises wrapping a roll of paper. 
   
   
       13 . The method of  claim 9  wherein wrapping a roll of sheet material with a wetness indicating wrap system comprises wrapping a roll of sheet material with a wetness indicating wrap system comprising a roll wrap system having water soluble indicia thereon. 
   
   
       14 . A wrapped roll of sheet material comprising:
 (a) a roll of sheet material having a first end and an opposite second end; and   (b) a wetness indicating wrap system comprising a roll wrap system at least partially covering the roll, the roll wrap system having a water contact indicator thereon and comprising at least one of an outer wrap of material wrapped circumferentially around the roll and an outer header covering at least one end of the roll.   
   
   
       15 . The wrapped roll of  claim 14  wherein the roll wrap system comprises both an outer wrap of material and an outer header. 
   
   
       16 . The wrapped roll of  claim 15  wherein each of the outer wrap and the outer header has the water contact indicator thereon. 
   
   
       17 . he wrapped roll of  claim 15  wherein one of the outer wrap and the outer header has the water contact indicator thereon. 
   
   
       18 . The wrapped roll of  claim 14  wherein the water contact indicator comprises indicia formed from a water soluble dye. 
   
   
       19 . The wrapped roll of  claim 18  wherein the water soluble indicia is alphanumeric. 
   
   
       20 . The wrapped roll of  claim 18  wherein the water soluble indicia comprises a repeating pattern.
