Patent

CA 2247026

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.

L'invention concerne un film uniaxialement orienté (10) comprenant un film polymère (16) constitué d'au moins une couche, une strate d'alvéoles étant disposée à l'intérieur du film. Les alvéoles donnent au film une opacité supérieure à 30 % environ. L'invention concerne également un film uniaxialement orienté comprenant un film polymère constitué d'au moins une couche, une strate d'alvéoles dans laquelle pratiquement tous les alvéoles sont fermés étant disposée à l'intérieur du film. L'invention concerne aussi un procédé permettant d'orienter un film alvéolé, qui consiste à orienter un film, constitué essentiellement de particules amorçant des alvéoles non sphériques, de sorte que celui-ci présente une opacité supérieure à 30 % environ. L'invention concerne enfin le procédé permettant d'orienter uniaxialement les films ci-dessus.
