THE INVENTION
The invention is directed to a multilayer film facestock. The facestock comprises a
coextrudate of at least two layers comprising a base layer and at least one face layer. The
base layer is free of filler particles and has a stiffness of from about 10 to 100 Gurley.
Additional limitations are provided in the following illustrative claim.
THE CLAIM
Claim 54 is illustrative of appellant’s invention and is reproduced below:
54. A die-cuttable and matrix strippable multilayer film facestock having an
overall thickness of from 1.5 mils to about 6.5 mils for use in pressure-sensitive
adhesive label applications comprising a coextrudate of at least two layers
comprising a base layer and at least one skin layer wherein the base layer is thicker
than the skin layer, said coextrudate having a face side, said base layer comprising a
polyethylene having a density of from 0.89 to 0.965 free of filler particles, and
having a stiffness of from about 10 to 100 Gurley, and said skin layer being on the
face side of the coextrudate and having an ink-printable surface.
