An improved foam cushioning tape is a composite reinforced film comprising a compressible polyurethane foam layer having a first side and an opposite second side, a fixing layer and a reinforcing layer, wherein the polyurethane foam first A composite reinforced film having two side surfaces disposed on a fixing layer of the composite reinforced film, a first adhesive disposed on a first side surface of the compressible polyurethane foam, and the composite reinforced film. And a second adhesive disposed on the reinforcing layer. The fixing layer includes at least one non-olefin polymer such as polyvinylidene chloride (PVDC), polyurethane, or nylon. Casting a curable polyurethane foam composition directly onto a fixing layer of a composite reinforced film having a first fixing layer and a second reinforcing layer, and then curing the foam composition to produce a compressible polyurethane foam. There is further provided an economical method of manufacturing a thin foam cushioning tape for flexographic printing, including forming. |
