The protective wrapper of  claim 1 , wherein the layer of protective material is superposed to a side of the first layer of paper material and wherein the protective wrapper further comprises a second layer of protective material superposed to another side of the first layer of paper material, the second layer of protective material not overlapping the edge strip. 
     
     
         6 . The protective wrapper of  claim 3 , wherein at least one of: the first layer of paper material and the second layer of paper material includes a material in the group consisting of: a conventional type of flexible paper, a flexible type of flexible cardboard, a linerboard, a laminated paper, a virgin Kraft paper, a recycled paper or a combination thereof. 
     
     
         7 . The protective wrapper of  claim 1 , wherein the edge strip comprises two edge strips, each one of the two edge strips is for being inwardly crimped against a corresponding one of the two ends of the roll. 
     
     
         8 . The protective wrapper of  claim 7 , further comprising two inner roll headers installed at each one of the two ends of the roll and wherein the two edge strips are for being inwardly crimped against the two inner roll headers. 
     
     
         9 . The protective wrapper of  claim 1 , further comprising an outer roll header for covering at least partially at least one of the two ends and the crimped edge strip, thereby providing protection against the elements at at least one of the two ends of the roll. 
     
     
         10 . The protective wrapper of  claim 1 , further comprising an inner roll header to be installed at at least one of the two ends of the roll and wherein the edge strip is for being inwardly crimped against the inner roll header. 
     
     
         11 . The protective wrapper of  claim 10 , wherein the inner roll header covers at least partially at least one of the two ends of the roll. 
     
     
         12 . The protective wrapper of  claim 10 , wherein the inner roll header defines a disc-like shape. 
     
     
         13 . The protective wrapper of  claim 9 , wherein the outer roll header defines a disc-like shape 
     
     
         14 . The protective wrapper of  claim 13 , wherein the inner roll header defines a disc-like shape and wherein the disc-like shape of the inner roll header and the disc-like shape of the outer roll header define an equivalent disc-like shape. 
     
     
         15 . The protective wrapper of  claim 14 , further comprising a layer of heat sensitive material coated to at least one of: the inner roll header and the outer roll header for linking the at least one of: the inner roll header and the outer roll header with the crimped edge strip, the layer of heat sensitive material having a surface area not exceeding another surface area of the ends of the roll. 
     
     
         16 . The protective wrapper of  claim 9 , wherein the outer roll header comprises two outer roll headers and the inner roll header comprises two inner roll headers, one of each for each one of the two ends of the roll. 
     
     
         17 . The protective wrapper of  claim 9 , wherein at least one of: the outer roll header and the inner roll header further comprises adhesive properties for being linked with the crimped edge strip and wherein the adhesive properties are activated by heat, infrared, ultraviolet light, ultrasound, pressure, microwaves, radiowaves, X-rays or any combination thereof. 
     
     
         18 . A protective wrapper for a roll having two ends and a length defining a distance between the two ends, the protective wrapper comprising:
 an inner roll header to be installed at at least one of the two ends;   a first layer of paper material having two opposed edges and an edge strip at at least one of the two opposed edges of the first layer of paper material, the edge strip comprises one and only one layer of the paper material and the edge strip is for being inwardly crimped against the inner roll header;   a layer of protective material superposed to the first layer of paper material, the layer of protective material not overlapping the edge strip; and   an outer roll header for covering at least partially the inner roll header and the crimped edge strip, thereby providing protection against the elements at at least one of the two ends of the roll;   wherein the first layer of paper material has a width greater than the distance between the two ends of the roll.   
     
     
         19 . The protective wrapper of  claim 18 , wherein the edge strip comprises two edge strips, each one of the two edge strips is for being inwardly crimped against a respective inner roll header at a corresponding one of the two ends of the roll. 
     
     
         20 . A method for wrapping a roll having two ends and a length defining a distance between the two ends, the method comprising the steps of:
 installing an inner roll header at at least one of the two ends of the roll;   wrapping the roll with a first layer of paper material having a width greater than the length of the roll and an edge strip which comprises one and only one layer of the paper material, the first layer of paper material being superposed to a layer of protective material which has a width not exceeding the distance between the two ends of the roll; and   inwardly crimping the edge strip against at least one of the two ends of the roll for contributing to the reduction of overlapped areas and crimp tunnels on the at least one of the two ends.
