ALIPHATIC POLYCARBONATE EXTRUSION COATINGS

摘要

A laminate includes paper or paperboard and at least one extrusion-coated layer including at least one aliphatic polycarbonate. In some embodiments, the extrusion-coated layer substantially includes only an aliphatic polycarbonate. In some embodiments, the extrusion-coated layer includes a polymer blend of an aliphatic polycarbonate and at least one other polymer, which may also be an aliphatic polycarbonate. In some embodiments, the extrusion-coated layer is applied without a tie layer. In some embodiments, the aliphatic polycarbonate is poly(ethylene carbonate). In some embodiments, the aliphatic polycarbonate is poly(propylene carbonate). In other embodiments, the aliphatic polycarbonate is not poly(propylene carbonate).
