Multi-layer opaque films, articles including such films, and uses thereof |
| 摘要 |
A multi-layer film including a cavitated core layer, two skin layers and at least one tie layer between the core layer and one of the skin layers, said tie layer including from about 1 to about 25 wt % of a soft polymer having a density in the range of 0.850 g/cm3 to 0.920 g/cm3 and a Differential Scanning Calorimetry (DSC) melting point in the range of 40° C. to 125° C., said multi-layer film having a density between 0.50 to 0.85 g/cm3. |

1. A multi-layer film comprising a cavitated core layer, two skin layers and at least one tie layer between the core layer and one of the skin layers, said tie layer comprising from about 1 to about 25 wt % of a soft polymer having a density in the range of 0.850 g/cm3 to 0.920 g/cm3 and a Differential Scanning Calorimetry (DSC) melting point in the range of 40° C. to 125° C., and from 75 to 99 wt % of at least one alpha-olefin polymer having a higher DSC melting point than the soft polymer or blend thereof, said multi-layer film having a density between 0.50 to 0.85 g/cm3. |
