Abstract
Film constructions and articles including the film constructions, wherein a film construction includes: a backing having a first major surface and a second major surface, wherein the backing includes at least one backing layer comprising a polylactic acid and an ethylene-containing copolymer comprising a polar comonomer; a tie layer disposed on the first major surface of the backing; and a release layer disposed on the tie layer.
Claims20
A film construction comprising:
- a backing having a first major surface and a second major surface, wherein the backing comprises at least one layer comprising a polylactic acid and an ethylene-containing copolymer comprising a polar comonomer;
- a tie layer disposed on the first major surface of the backing;
- and
- a release layer disposed on the tie layer.
A film construction comprising:
- a backing having a first major surface and a second major surface, wherein the backing comprises at least one layer comprising a polylactic acid and an ethylene-containing copolymer comprising a polar comonomer;
- a tie layer disposed on the first major surface of the backing, wherein the tie layer comprises at least two different ethylene-containing copolymers, each independently comprising a polar comonomer;
- and
- a release layer disposed on the tie layer, wherein the release layer comprises an extrudable material.
A film construction comprising:
- a backing having a first major surface and a second major surface, wherein the backing comprises at least one layer comprising a polylactic acid and an ethylene-containing copolymer comprising a polar comonomer;
- a tie layer disposed on the first major surface of the backing, wherein the tie layer comprises at least two different ethylene-containing copolymers, each independently comprising a polar comonomer;
- and
- a release layer disposed on the tie layer, wherein the release layer comprises a polyolefin, an ethylene-containing copolymer comprising a polar comonomer, a polyalkyl siloxane, a polyurethane, or a combination thereof.
