a density of at least about 0.94, said first layer
being oriented in the transverse direction (TD) to a
degree which is at least three times greater than
the degree of orientation present in the machine
direction (MD) to
(b) a second layer comprising inner and outer
sides, comprising at least about 50 weight
percent of a high density polyethylene having a
density of at least about 0.94, said second
layer being oriented in the transverse direction
to a degree which is at least three times
greater than the degree of orientation present
in the machine direction, with a laminating
adhesive resin which comprises a component
selected from the group consisting of low
density polyethylene (LDPE) and linear low
density polyethylene (LLDPE), said second layer
being laminated in the film substrate so that
said transverse direction of orientation of said
second layer is substantially aligned with said
transverse direction of orientation of said
first layer, thereby forming an embossable
substrate; and
ii) embossing said substrate.
