Patent

CA 2412512

The present invention provides a polymer blend suitable for use as a film or a coating, the polymer blend including from 1 to 99% by weight of a metallocene- produced VLDPE polymer having a density less than 0.916 g/cm3, and from 1 to 99% by weight of an LDPE polymer having a density of from 0.916 to 0.928 g/cm3 wherein the sum of (a) and (b) is 100%. The VLDPE polymer can have a melt index of from 6 to 15 dg/min, or from 9 to 12 dg/min. The present invention further provides polymeric films extrusion cast from such polymer blends, and articles having a flexible substrate and a polymeric film extrusion-coated on the substrate.

La présente invention concerne un mélange de polymère pouvant être utilisé comme film ou revêtement. Ce mélange de polymère comprend de 1 à 99 % en poids d'un polymère VLDPE à base de métallocène, dont la densité est inférieure à 0,916 g/cm<3 >et entre 1 et 99 % en poids d'un polymère LDPE dont la densité est comprise entre 0,916 et 0,928 g/cm<3>, où la somme de (a) et (b) est égale à 100 %. Le polymère VLDPE peut présenter un indice de fusion compris entre 6 et 15 dg/min, ou entre 9 et 12 dg/min. La présente invention concerne des films polymères coulés par extrusion à partir de ces mélanges de polymères, et des articles présentant un substrat flexible recouvert d'un film polymère, déposé par extrusion.
