ABSTRACT:
A method of making a laminated, thermally imageable tag, such as a baggage tag, as made from a top sheet. The top sheet is precoated on one surface with a thermally sensitive material. A hot-melt adhesive is applied to the bottom sheet. The top sheet, the reinforcing fibers, and the bottom sheet are pressed together, as by two pressing rolls defining a nip. A laminate thus is formed with the reinforcing fibers between the top and bottom sheets. The hot-melt adhesive is applied and the top sheet, the reinforcing fibers, and the bottom sheet are pressed together under conditions insuring that the thermally sensitive material is not heated to its activation temperature by heat transfer from the hot-melt adhesive, through the top sheet, to the thermally sensitive material.
