  • Adhesive paper material and a label made from such material
    Patent number: 4619858
    Abstract: A web for the production of self-adhesive paper labels consists of thin paper web and a very thin plastic sheet of polyester or a similar material of high tensile strength and low initial stretchability, yet of low tear strength due to its small thickness, e.g. 12 .mu.m. Labels of such a web show a high tensile strength and a good flexibility, while they show a sufficient low tear strength to be usable as guarantee labels. In the production of the labels as left on a co-laminated backing sheet the so-called `waste` may be drawn off at high speed, whereby the production may run at increased speed.
