A double layer label with “dry adhesive” or adhesive-free strip.
Combining a self-adhesive label with a coupon is possible. We either use the so called dry adhesive which becomes deactivated once the top layer has been peeled off from the bottom layer or we apply adhesive selectively to allow only one part of the label to be peeled off and be used later as a coupon (one or double layer).
Another solution is a coupon that is hidden in between two adhering layers.
Promotional or discount campaigns, or loyalty programmes.
