Appeal No. 2005-0279
Application No. 10/036,708
these layers, and a tie layer of elastomeric material disposed
between the layers and holding the reinforcing grid but allowing
slippage of the grid in the tie layer upon tensile loading,
wherein the first and second layers, the reinforcing grid and the
tie layer are extrusion laminated together to form the reinforced
shrink wrap and wherein the elastomeric tie layer has a lower
modulus than at least one of the thermoplastic layers. This
appealed subject matter is adequately represented by appealed
independent claim 1 which reads as follows:
1. An extrusion-laminated reinforced shrink wrap
comprising:
a first layer of thermoplastic;
a second layer of thermoplastic;
at least one layer of said first and second layers
comprising a shrink film of highly irradiated polyolefin;
a reinforcing grid disposed between the first and
second layers of thermoplastic; and
a tie layer of elastomeric material disposed between
the first layer and the second layer holding the reinforcing
grid but allowing slippage of the reinforcing grid in the
tie layer upon tensile loading,
wherein the first layer, the second layer, the
reinforcing grid and the tie layer are extrusion laminated
together to form the reinforced shrink wrap, and wherein the
elastomeric tie layer has a lower modulus than at least one
of the thermoplastic layers.
