Abstract
A paper-plastic laminate sheeting whose paper ply incorporates heat-activatable material that renders the sheeting useable for producing baggage tags and other products when heat-activated are then bar-coded or otherwise identified. In a system for producing the laminate sheeting, the paper ply is cold-laminated by a water-based adhesive to an oriented synthetic plastic film ply of high strength, whereby neither the heat-activatable material in the paper ply nor the orientation of the film ply is disturbed thereby.
