Abstract

A method of making a thermoplastic laminate includes the steps of extruding a tubular polymeric film; collapsing the extruded film to form a layflat film; slitting the edges of the collapsed film to form two plies; taking up both plies of the slit film onto a single take up roll to form a double wound film with two plies, the film having first and second outside surfaces; corona treating the first outside surface of the double wound film; applying a varnish to the treated surface; printing the varnished surface; corona treating the second outside surface of the double ground film; and taking up the printed film onto a wind-up roll such that the treated printed surface of one ply of the film in the roll bonds to the treated second outside surface on an adjacent wind in the roll, thereby forming a laminate. Alternatively, two separate films may be taken up on a take up roll to form a double wound film, and processed as described. The result is a trap printed laminate with good machinability and other properties.
