Patent ID: 8047752

Claim:
A fastener assembly for use in a fastener driving tool, comprising: a. a plurality of fasteners; b. a multi-layered structure including i. a first polymeric layer having a first surface for contacting the fasteners and a second surface and including a thermoplastic polymer backbone having at least 0.03% grafted maleic anhydride by weight of the first polymeric layer; ii. a second polymeric layer disposed on the first polymeric layer on the second surface, the second polymeric layer being sufficiently rigid for reinforcing the first polymeric layer, wherein the second polymeric layer includes an inorganic filler in an amount of about 3 to about 45% by weight of the second polymeric layer; and wherein the plurality of fasteners are carried on the multi-layered structure; wherein each of the first layer and the second layer have a substantially constant thickness over its length, and the ratio of the thickness of the first layer to the second layer ranges from about 1:25 to about 3:1; wherein the fastener assembly is prepared by a process including a first step of extrusion coating a backing layer with the first polymeric layer and the second polymeric layer, or a first step of co-extruding the first polymeric layer and the second polymeric layer without a backing layer, to form the multi-layered structure; and a second step of engagingly contacting the multilayered structure to the plurality of fasteners; and wherein the first polymeric layer includes a polar functional moiety that provides adhesion to the fasteners.
