Abstract
The invention provides a film comprising at least two layers, a first layer and a second layer; and wherein the first layer is formed from a first composition comprising a polyester and/or a polylactic acid; and wherein the second layer is formed from a second composition comprising at least the following: A) a functionalized ethylene-based polymer, and B) at least one ethylene/alkylacrylate copolymer.
Claims12
A film comprising at least two layers, a first layer and a second layer;
- and wherein the first layer is formed from a first composition comprising a polyester and/or a poly lactic acid;
- and
- wherein the second layer is formed from a second composition comprising at least the following:
- A) 20 to 50 wt %, based on the sum weight of component A and component B, of a maleic anhydride (MAH) grafted ethylene/octene copolymer,
- B) an ethylene/alkylacrylate copolymer, and
- C) a low density polyethylene (LDPE), and wherein the LDPE is present in an amount from 10 to 50 weight percent, based on the weight of the second composition;
- and
- wherein the ethylene/alkylacrylate copolymer of component B (second composition) has a melting point (Tm) greater than, or equal to, 93° C., as determined by DSC;
- and a density from 0.910 to 0.940 g/cc;
- and
- wherein the weight ratio of component B to component A (B:A) is from 4:1 to 1:1;
- and
- wherein the second composition has a melt index (12) from 1.5 to 12 g/10 min.
