Patent ID: 8071191

Claim:
A reinforced packaging web comprising: a substrate web having at least one surface; at least one strip disposed adjacent the substrate web surface such that an underside surface of the strip is disposed adjacent the substrate web surface; and an extruded polymer coating disposed adjacent both the substrate web and the strip such that the strip is sandwiched between the substrate web and the polymer coating and is affixed to the substrate web surface by an adhesive bond of the strip to the coating and of the substrate web surface to the coating and at least a significant portion of the underside surface of the strip is substantially free of an adhesive bond to the substrate web surface such that the underside surface of the strip is substantially unbounded to the substrate web surface and a substantial portion of an upper surface of the strip adjacent the polymer coating is bonded to the coating, whereby the strip can slide relative to the substrate to the extent permitted by the coating so as to strengthen the packaging web and resist tearing of the substrate.
