  • Patent number: 5221557
    Abstract: V-groovable gravure printable paper having the machinability of vinyl and the printability of paper, and a process for manufacturing such a product. A smooth, saturated only paper is subjected to heavy calendering during processing in order to provide adequate smoothness as required by printers. The paper is saturated with an acrylic/PVC blend designed to give good "miter-fold" strength, good smoothness and adequate adhesive anchorage. The saturant also allows the ink types used on vinyl films to adhere to the paper, and exhibits good stain resistance.
