Abstract
A multi-layer label for displaying information is disclosed which includes at least two layers which may be repeatedly partially separated and re-adhered to one another, such that a portion of the outer surface of a lower layer is exposed upon separation of a portion of an upper layer from it. The inner surface of the upper layer of the label is coated with a pressure sensitive adhesive. To form a lift tab for the upper layer at least one corner of the inner surface is either coated with varnish to deaden the adhesive, or alternatively, a corner is not coated with adhesive. The outer surface of the lower layer is selectively coated with an adhesive release material such that the coated portion releasably bonds to the inner surface of the upper layer, and, the portion of the outer surface of the lower layer not coated with the adhesive release layer permanently bonds to the upper layer thus forming a hinge between the two layers. A method and apparatus for manufacturing a multi-layer label is also disclosed.
