Thin film strips

Abstract

A method of forming a thin film strip and thin film strips formed thereby where the method comprises coating a liner substrate with a wet slurry of film forming ingredients and other components and drying the wet slurry in a drying apparatus to form a film, measuring the moisture content of the film either during of upon exit from the drying apparatus, and storing the film in a minimal moisture loss environment during a curing process.

1 . A lightweight product composed of a mixture of film forming ingredients and other components manufactured by a method comprising: 
 coating a liner substrate with a wet slurry of the mixture of film forming ingredients and other components;    drying the wet slurry in a drying oven to form a film;    measuring a moisture content of the film as the film exists in the drying oven; and    storing the film in a minimal moisture loss environment during a curing process    where the lightweight product is in the form of a sheet comprising at least one layer where each of the at least one layer comprises at least one solid polymer selected from low-temperature-melt polymers and liquid soluble polymers, such polymer having at least one other component dispersed throughout the polymer matrix.    
     
     
         2 . The lightweight product of  claim 1  where the polymer is at least one solid low temperature melt polymer.  
     
     
         3 . The lightweight product of  claim 1  where the polymer is at least one liquid soluble polymer.  
     
     
         4 . The lightweight product of  claim 3  where the polymer is at least one water soluble polymer.  
     
     
         5 . The lightweight product of  claim 1  comprising at least two polymers.  
     
     
         6 . The lightweight product of  claim 1  where the polymers are in the form of a laminated film where each layer of the laminate contains a cosmetic or skin care active components and the cosmetic or skin care active components are selected from the same and different cosmetic or skin care active components.  
     
     
         7 . The lightweight product of  claim 6  where the laminated film contains layers laminated on top of each other.  
     
     
         8 . The lightweight product of  claim 6  where the laminated film contains layers laminated side by side.  
     
     
         9 . A lightweight cosmetic or skin care product composed of a mixture of film forming ingredients and other components and prepared by 
 coating a liner substrate with a wet slurry of the mixture of film forming ingredients and other components;    drying the wet slurry in a drying oven to form a film;    measuring a moisture content of the film as the film exists in the drying oven; and    storing the film in a minimal moisture loss environment during a curing process    where the lightweight product comprises dehydrated or encapsulated cosmetic or skin care active components dispersed within the matrix of a liquid soluble film forming polymer.    
     
     
         10 . The product of  claim 9  combined with sufficient liquid to dissolve the film forming polymer and release the cosmetic or skin care active components.  
     
     
         11 . The product of  claim 10  where the liquid is water.  
     
     
         12 . The product of  claim 1  where the thickness of the film is in the range of from about 0.25 to about 12 mils.  
     
     
         13 . The product of  claim 1  where the thickness of the film is in the range of from about 0.5 to about 2 mils.  
     
     
         14 . The lightweight product of claim  18  comprising one layer.  
     
     
         15 . The lightweight product of  claim 1  where the other component is an active component.  
     
     
         16 . The lightweight product of  claim 1  where the other component is a volatile active component.  
     
     
         17 . The lightweight product of  claim 1  where the other component is an inactive component.
