Patent

CA 2627019

The invention relates to perforated films comprising at least one layer, and to packages prepared from the same. Such packages contain a combination of perforation sizes and perforation densities that allows for effective air removal, during a filling, conveying, and palletizing process, and especially during the pressurized filling of fine powder substances. In particular, the invention provides a perforated film, comprising at least one layer, and wherein the at least one layer comprises perforations that are individually of a size less than, or equal to, 100 microns (µm), and wherein the ratio of the total perforation area to the total film surface area is from 400,000 to 2,000,000 square micron per square inch of film (µm)2/(in)2.

La présente invention a trait à des films perforés comportant au moins une couche, et à des emballages préparés à partir de ces films. De tels emballages contiennent une combinaison de tailles de perforation et de densités de perforation permettant une élimination d'air efficace, lors du remplissage, du transport, et du procédé de palettisation, et particulièrement lors du remplissage sous pression de substances en poudre fine. En particulier, l'invention a trait à un film perforé, comportant au moins une couche, et dans lequel ladite au moins une couche comprend des perforations qui sont individuellement d'une taille inférieure ou égale à 100 microns (?m), et dans lequel le rapport de la surface totale de perforation à la surface totale de film est compris entre 400,000 et 2,000,000 microns carrés par pouce carré (?m)2/pouce carré.
