Abstract
A label sheet comprises a substrate and an adhesive layer formed by applying an adhesive agent to a surface of the substrate, said adhesive layer being formed only on a limited area of the surface. With such an arrangement and if it is part of a larger label sheet or a multi-layer structure of label sheets, it can be stripped off easily from the remaining part. If perforations are formed in adhesive free areas, they do not produce any projections of the applied adhesive agent so that the final product can be handled with ease. Additionally, by forming an adhesive-repellent layer on the outer surface with an ink type adhesive-repellent agent, the overall manufacturing process can be simplified and the product is adapted to making by hand.
