Abstract

This invention relates to a livestock identification tag assembly comprising: (a) a heat seal laminate comprising: (i) a facestock having an upper surface and a lower surface; (ii) a heat-activatable adhesive layer having an upper surface and a lower surface, wherein the upper surface of the heat-activatable adhesion layer is adhered to the lower surface of said facestock; (iii) an ink or graphics layer adhered to the lower surface of said heat-activatable layer; and (b) a flexible polymeric substrate; wherein the lower surface of the heat-activatable adhesive of the laminate is adhered to the substrate. In one embodiment, the ink or graphics layer is positioned between said heat-activatable adhesive layer and said facestock.

Claims

1. A heat seal laminate comprising:

a facestock having an upper surface and a lower surface;

a heat-activatable layer adhered to said lower surface of said facestock;

a laminating adhesive overlying said upper surface of said facestock;

a carrier layer adhered to said laminating adhesive; and

the heat-activatable layer having an upper surface and a lower surface, the upper surface of the heat activatable layer being adhered to said lower surface of said facestock, a layer of ink or graphics overlying the lower surface of the heat-activatable layer;

said heat-activatable layer comprising a heat-activatable adhesive or thermoplastic film selected from the group consisting of polyolefins, polyamides, polyester copolymers, polyurethanes, ionomers based on sodium or zinc salts of ethylene methacrylic acid, polyacrylonitriles, ethylene-vinyl acetate copolymers, ethylene methacrylic acid, ethylene methyl acrylate, ethylene acrylic acid, ethylene ethyl acrylate, and mixtures of two or more thereof.

2. The heat seal laminate of claim 1 wherein said facestock comprises a single layer construction.

3. The heat seal laminate of claim 1 wherein said facestock comprises a multi-layered construction.

4. The heat seal laminate of claim 1 wherein said heat-activatable layer comprises a polyurethane based adhesive.

5. The heat seal laminate of claim 1 wherein said facestock comprises a polyvinyl chloride film.

6. The heat seal laminate of claim 1 wherein said laminating adhesive comprises a radiation-cured adhesive material or a removable pressure-sensitive adhesive material.

7. The heat seal laminate of claim 1 wherein said laminating adhesive comprises a radiation-cured adhesive material.

8. The heat seal laminate of claim 1 further comprising a detack layer having an upper surface and a lower surface, the upper surface of said detack layer adhered to the lower surface of the heat-activatable layer, the layer of ink or graphics being printed on the lower surface of the detack layer.
