Abstract
A multiple layered laminated tape has a permeable layer on its face. The permeable layer provides a suitable surface for printing or marking. The permeable layer is laminated to an upper strength layer made of a film of pre-stretched polypropylene or the like. The upper strength layer is laminated to a weak carrier layer of low bond Kraft paper. The carrier layer has a layer of water soluble adhesive which is used to secure the tape to a cardboard carton or the like. The water soluble adhesive is also suitable for sticking to the permeable layer face of the tape so that the tape may be stuck to itself. Labels, stamps or the like having a water soluble adhesive may also be glued to the face of the tape.
