ABSTRACT:
A foam cushion tape comprising a compressible polyurethane foam layer having a first side and an opposite second side; a composite reinforcing film comprising an anchoring layer and a reinforcing layer, wherein the second aide of the polyurethane foam is disposed on the anchoring layer of the reinforcing film; a first adhesive disposed on the first side of the compressible polyurethane foam; and a second adhesive disposed an the reinforcing layer of the composite reinforcing film. The anchoring layer comprises at least one non-olefinio polymer, such as polyvinylidene chloride (PVDC), polyurethane, nylon, or the like. A method for the manufacture of thin, foam cushion tapes for flexographic printing is provided, comprising casting a curable polyurethane foam composition directly onto the anchoring layer of a composite reinforcing film having a first anchoring layer and a second reinforcing layer, followed by curing the foam composition to form a compressible polyurethane foam.
