PROBLEM TO BE SOLVED: To reliably determine whether wrinkles of a resin film roll for food packing are within an allowable range.SOLUTION: An inspection method of a resin film roll for food packing includes: a step S1 of providing a resin film roll for food packing served as analyte; a step S2 of measuring brightness L, chromaticity aand bof the analyte in accordance with an Labcolorimetric system; a step S3 of providing saturation Caccording to the chromaticity aand b; a step S4 of branching by whether saturation Cexceeds a predetermined threshold value; a step S5 of determining an analyte having saturation Cexceeding the predetermined threshold value as acceptance; and a step S6 of determining as unacceptance in the other case.SELECTED DRAWING: Figure 3 |
