Patent

CA 2226865

A combination of lamellar and spherical particulates provides a film with desired slip and antiblock characteristics, in the absence of loose dust on the surface of the film. The film exhibits improved Machinability over comparative films having either lamellar or spherical particulates. The invention is also directed to a composition of matter comprising a polymer having the mixture of lamellar and spherical particulates.

La présente invention concerne une combinaison de particules lamellaires et sphériques qui permet à un film d'acquérir les caractéristiques de glissement et d'antiadhérence souhaitées, en l'absence de toute poussière mobile à sa surface. Ledit film a une aptitude au traitement en machine meilleure que celle de films comparables, dotés soit de particules lamellaires, soit de particules sphériques. En outre, la présente invention concerne une composition de matière comprenant un polymère qui contient ledit mélange de particules lamellaires et sphériques.
