Coextruded Multilayer Film with Propylene-Based Polymer and Ethylene-Based Polymer |
| 摘要 |
The present disclosure provides a coextruded multilayer films. In one embodiment, 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 30 nm to 1000 nni and layer A includes a propylene-based polymer having a crystallization temperature (TPc). Layer B includes an ethylene-based polymer having a crystallization temperature (TEc), wherein TPc<TEc. Layer A has an effective moisture permeability less than 0.40 g-mil/100 in2/day. |
