This invention relates to a method for equipping packages with indicators and to an indicator system for indicators based on colour reactions, used for instance in food industry packaging. In the invention, an indicator (1) of a generally applicable structure and shape is placed on the inside of a package consisting of transparent packaging film (2), and, essentially, all the information related to interpreting the indicator is printed on the outside of the package, either onto the packaging film (2) itself or onto a label (3), which is then stuck to the package. |
