发明名称 Reinforced Packaging Webs
摘要 The specification discloses a method for affixing a strip to an underlying web substrate. According to the method, a substrate web having at least one surface is provided and at least one strip is applied over at least a portion of the substrate surface such that at least a significant portion of an underside surface of the strip disposed adjacent the substrate surface is unbounded to the substrate. A polymer coating is extruded over both the substrate surface and the strip. The strip is thereby affixed to the substrate surface by the coating while the portion of the underside surface of the strip remains substantially unbounded to the substrate surface. At the same time, a substantial portion of an upper surface of the strip adjacent the polymer coating layer is bonded to the coating layer. Also disclosed are packaging materials formed from the reinforced substrate.
