Voided uniaxially oriented films |
摘要 |
The invention is a uniaxially oriented film (10) comprising a polymer film (16) of at least one layer wherein within the layer is located a strata of voids. The voids cause the film to have an opacity greater than about 30 %. The invention is further a uniaxially oriented film comprising a polymer film of at least one layer wherein within the layer is located a strata of voids wherein essentially all of the voids are closed. The invention is further a process for orienting a voided film comprising the step of orienting a film consisting essentially of non-spherical void initiating particles wherein the particles cause the film to have an opacity greater than about 30 %. The invention is further the process for uniaxially orienting the above films. |
