A double layer speciality label – peel off the top layer and re-apply elsewhere.
Two or three self-adhesive layers combined together, where the entire or part of the top layer can be peeled off from the bottom layer and re-applied elsewhere (to identify a batch) or used as a coupon.
For the purpose of documenting the use of a product by means of applying the batch number of the product, e.g. a vaccine.
For promotional campaigns, collectible labels or discount coupons.
