HIGH CLARITY AND STRENGTH POLYETHYLENE FILMS |
| 摘要 |
A film having an A/B/A structure comprising an layer A and a layer B. The layer A is present in an amount ranging from 25 to 65 wt. %, based upon the total weight of the A/B/A structure, and the layer A comprises a first A layer and a second A layer each independently comprise linear low density polyethylene. The layer B is present in an amount ranging from 35 to 75 wt. %, based upon the total weight of the A/B/A structure, and the layer B, which comprises high density polyethylene, is positioned between the first A layer and the second A layer. |

1. A film having an A/B/A structure comprising:
(A) a layer A, wherein the layer A:
(i) is present in an amount ranging from 25 to 65 wt. %, based upon the total weight of the A/B/A structure, and(ii) the layer A comprises a first A layer and a second A layer, the first A layer and second A layer each independently comprise linear low density polyethylene; and (B) a layer B, wherein the layer B comprises high density polyethylene:
(i) is present in an amount ranging from 35 to 75 wt. %, based upon the total weight of the A/B/A structure,(ii) the layer B is positioned between the first A layer and the second A layer,wherein the film has a gauge from 0.7 to 1.8 mils, andwherein the film has a water vapor transmission rate of 0.25 to 0.95 g/100 si/day. |
