I have a roll of clear plastic pallet wrapping film with the following criteria :\r
\n" ); document.write( "\n" ); document.write( "Total roll weight - 14.58 kilogram
\n" ); document.write( "Inner core weight - 1.554 kilogram
\n" ); document.write( "Film weight - 13.026 kilograms (total roll weight less core weight)
\n" ); document.write( "Film width - 500mm
\n" ); document.write( "Film Thickness - 17 microns\r
\n" ); document.write( "\n" ); document.write( "How can I work out the true linear length of the film without unrolling it, as the unrolling process will stretch the film and give a false measurement?
\n" ); document.write( "And is the same calculation used for different micron thicknesses?
\n" ); document.write( "============
\n" ); document.write( "More info is needed.
\n" ); document.write( "If you have the density, the length can be calculated.
\n" ); document.write( "-----
\n" ); document.write( "Or, the inside and outside diameter of the roll.
