Patent ID: 7294380

Claim:
A clear polymeric film structure for producing labels that are removable, comprising: (a) a core layer that has a first side and a second side, wherein the core layer comprises a film-forming thermoplastic polymer; (b) a first skin layer that has a first side and a second side, wherein the first skin layer comprises polylactic acid polymer (PLA); (c) a second skin layer that has a first and a second side, wherein the second skin layer comprises a film-forming thermoplastic polymer; and (d) a first tie layer that has a first side and a second side, wherein the first tie layer comprises a film-forming thermoplastic olefin polymer, the first side of the first tie layer is adjacent to the second side of the first skin layer, and the second side of the first tie layer is adjacent to the first side of the core layer; wherein each layer of the film structure is non-cavitated and the film structure is essentially free of cavitating and opacifying agents and the core layer is located between the first and second skin layers.
