Abstract | Embodiments of the present invention relate to multilayer films, bags, and other articles. In one aspect, a multilayer film comprises at least three layers: (a) a first skin layer, (b) a core layer, and (c) a second skin layer opposite the first skin layer. Among other features, the first skin layer and the core layer, while having different overall compositions, each comprise from 0.05 weight percent to 5.0 weight percent of at least one polydimethylsiloxane, based on the total weight of the respective layer, wherein at least one of the polydimethylsiloxane has a weight average molecular weight, Mw, of from 20,000 g/mol to 700,000 g/mol.
Des modes de réalisation de la présente invention concernent des films multicouches, des sacs et d'autres articles. Selon un aspect, un film multicouche comprend au moins trois couches : (a) une première couche de peau, (b) une couche de cœur et (c) une seconde couche de peau opposée à la première couche de peau. Parmi d'autres caractéristiques, la première couche de peau et la couche de cœur, tout en ayant différentes compositions globales, comprennent chacune de 0,05 pour cent en poids à 5,0 pour cent en poids d'au moins un polydiméthylsiloxane, sur la base du poids total de la couche respective, au moins l'un du polydiméthylsiloxane ayant un poids moléculaire moyen en poids, Mw, de 20 000 g/mol à 70 000 g/mol. |
