Flexible packaging (31, 32) is provided with a bar code (20). A method is provided for applying the bar code (20) to flexible packaging material (31, 32). An opaque coating of reflective color is applied on a surface of the material in a bar code pattern in which non-reflective bars (51) are defined by uncoated strips of the transparent material and in which reflective spaces (53) between the bars are defined by the opaque coating. |
