ABSTRACT:
A method of manufacturing multi-ply tubular containers for food products is provided including the steps of advancing a continuous body ply formed of paperboard towards a shaping mandrel and advancing a continuous polymeric liner ply adjacent to one surface of the paperboard body ply. The polymeric liner ply includes a moisture barrier layer and an adhesive layer defining one surface of the liner ply, wherein the adhesive layer includes a polymeric adhesive which is activated at a predetermined activation temperature. The body ply is heated to a temperature above the activation temperature of the adhesive, and the body ply and the liner ply are then passed in face-to-face contact through a nip to adhere the liner ply to the body ply. The body ply and liner ply are then wrapped around a shaping mandrel to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having an unsupported and polymeric liner ply which is adhered to a body ply without the application of any separate adhesives.
