Abstract:
Embodiments of the present disclosure are directed to laminates comprising a uniaxially oriented first multilayer film comprising ethylene-based polymer, wherein the uniaxially oriented first multilayer film has a ratio of percent elongation at break in the cross direction to percent elongation at break in the machine direction of at least 2 to 1; a biaxially oriented second multilayer film adhered to the uniaxially oriented first multilayer film and comprising an ethylene-based polymer, wherein the biaxially oriented second multilayer film has a ratio of percent elongation at break in the machine direction to percent elongation at break in the cross direction of at least 2 to 1; and a third film adhered to the biaxially oriented second multilayer film such that the biaxially oriented second multilayer film is disposed between the uniaxially oriented first multilayer film and the third film, wherein the third film comprises an ethylene-based polymer.
