MICROPERFORATED POLYMERIC FILM AND METHODS OF MAKING AND USING THE SAME |
| 摘要 |
Described herein are microperforated polymeric films comprising: opposed first and second surfaces separated by a first certain distance; and a plurality of channels perpendicular to the first and second surfaces, wherein a first opening of a channel intersects the first surface and a second opening of the channel intersects the second surface; wherein the diameter of the first opening is larger than the diameter of the second opening and the second openings on the second surface are spaced apart by a second certain distance; wherein the ratio of the first certain distance to the second certain distance is at least 0.25; and further;wherein the second surface has an open area of at least 10%. Also described are methods of making and using such microperforated polymeric films. |

1. A microperforated polymeric film comprising: comprising: (i) opposed first and second surfaces separated by a first certain distance; and (ii) a plurality of channels perpendicular to the first and second surfaces, wherein a first opening of each channel intersects the first surface and a second opening of each channel intersects the second surface; wherein the diameter of the first opening is larger than the diameter of the second opening and the second openings on the second surface are spaced apart by a second certain distance; wherein the ratio of the first certain distance to the second certain distance is at least 0.25; and further
wherein the second surface has an open area of at least 10%. |
