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.
Claims11
In an improved multiple layered tape;
- a non-adhereable plastic, strength layer of the tape not suited for the adherence to it of water-soluble glue, a carrier layer united on one side of the non-adhereable layer and capable of holding a water-soluble adhesive and a water-soluble adhesive film, suitable for adherence to cartons and the like, on the side of the carrier layer opposite the non-adhereable layer, a permeable layer united to the surface of the non-adhereable layer on the side opposite the carrier layer, said permeable layer being a surface suitable to be written or printed upon and said permeable layer capable of being adhered to by the water-soluble adhesive film.
A thin tape for such use as sealing carton tops together, comprising a thin film of strong plastic material to provide a strength layer, a thin permeable layer united to one side of the strength layer;
- a weak, thin carrier layer united to the other side of the strength layer;
- and a water-soluble adhesive film on the opposite side of the carrier layer, said permeable layer able to be adhered to by said water-soluble adhesive film;
- the strength layer of plastic material being non-rigid, flexible and floppy, and hence unable to be dispensed lengthwise from a tape dispenser, the permeable layer suited to be written or printed upon, and the plastic being unable to hold a coating of water-soluble adhesive, the carrier layer being of thin paper-like material continuous and unbroken laterally across the strength layer, the carrier material being capable of holding the water-soluble adhesive film, and also of being united to the plastic film, and the adhesive film being on the exposed face of the carrier layer opposite the plastic film.
