ABSTRACT:
The present invention relates to a method and system for producing a label comprising a folded sheet which is sealed between two webs, one of which is transparent. One of the webs is self-adhesive and is provided from pressure-sensitive stock which has had the release backing material removed. A succession of sheets are applied to the self-adhesive surface of the web and then the other web is laminated over the adhered sheets by being adhered to the exposed self-adhesive surface. The composite web is then cut into individual labels.
