Abstract
Embodiments of the present invention relate to multilayer films, laminates, and articles. In one aspect, a multilayer film includes at least three layers: (a) a first layer. (b) a second layer, and (c) a third layer. Among other features, the second layer includes from 0.05 weight percent to 5.0 weight percent of at least one polydimethylsiloxane, based on the total weight of the second layer, wherein at least one of the poly dimethylsiloxane has a weight average molecular weight, Mw, of from 20,000 g/mol to 700,000 g/mol.
Claims17
A multilayer film comprising at least three layers:
- (a) a first layer comprising at least one polyolefin having a density of 0.87 g/cm3 to 0.97 g/cm3, wherein the first layer comprises at least 90 weight percent polyolefin based on the total weight of the first layer, and having an outer surface and an inner surface, wherein the outer surface is an outermost surface of the multilayer film;
- (b) a second layer having a first surface and a second surface, the second layer comprising:
- (1) at least one polyolefin having a density of 0.87 g/cm3 to 0.97 g/cm3, wherein the second layer comprises at least 90 weight percent polyolefin based on the total weight of the second layer;
- and
- (2) from 0.05 weight percent to 5.0 weight percent of at least one polydimethylsiloxane, based on the total weight of the second 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;
- and
- (c) a third layer, wherein the third layer has a first surface and a second surface, wherein the first surface of the third layer is in adhering contact with the second surface of the second layer, wherein the third layer comprises ethylene vinyl alcohol or polyamide.
