Coextruded Multilayer Film with Barrier Properties |
| 摘要 |
The disclosure provides a coextruded multilayer film. The coextruded multilayer film includes a core component having from 15 to 1000 alternating layers of layer A and layer B. Layer A has a thickness from 100 nm to 500 nm and includes an ethylene-based polymer. Layer B has a thickness from 100 nm to 500 nm and includes a cyclic olefin polymer (“COP”). Layer A has an effective moisture permeability less than 0.20 g-mil/100 in2/day and an effective oxygen permeability less than 150 cc-mil/100 in2/day/atm. In an embodiment, the multilayer film includes skin layers. |
