摘要： A multilayer coextruded film which includes at least one oil and grease absorbing layer and at least one oil barrier layer. The at least one oil and grease absorbing layer includes at least one styrenic block copolymer. Each oil barrier layer includes one or more polyolefins. Some multilayer coextruded films include an interior sealing layer. Further multilayer coextruded films include an exterior finishing layer with the oil barrier layer and the oil and grease absorbing layer disposed between the interior sealing layer and the exterior finishing layer.

摘要： The present invention provides uniaxially oriented films and packages formed from such films. In one aspect, a uniaxially oriented film comprises (a) a first layer comprising a polyolefin plastomer having a density of 0.865 to 0.908 g/cm 3 and a melt index (I 2 ) of 0.5-6 g/10 minutes, and at least one of a single-site catalyzed linear low density polyethylene having a density of 0.912 g/cm 3 to 0.935 g/cm 3 and a melt index (I 2 ) of 0.5 to 6 g/10 minutes, or a Ziegler-Natta catalyzed ultra low density polyethylene having a density of 0.880 g/cm 3 to 0.912 g/cm 3 , a melt index (I 2 ) of 0.5 to 6 g/10 minutes, and a MWD of 6.0 or less; (b) a second layer comprising a Ziegler-Natta catalyzed ultra low density polyethylene having a density of 0.880 g/cm 3 to 0.912 g/cm 3 , a melt index (I 2 ) of 0.5 to 6 g/10 minutes, and a MWD of 6.0 or less; and (c) at least one inner layer between the first layer and the second layer comprising at least one polyolefin. The film is oriented in the machine direction at a draw ratio of between 4:1 and 10:1, and can exhibit a machine direction 2% secant modulus of 85,000 psi or more when measured as per ASTM D882.

In one aspect, a uniaxially oriented film comprises (a) a first layer comprising (i) a first composition comprising an ethylene-based polymer prepared in the presence of a single-site catalyst, wherein the first composition has a density of 0.935 g/cm3 to 0.965 g/cm3, a melt index (I2) of 0.5 to 6 g/10 minutes, and a MWD of 6.0 or less, and (ii) a Ziegler-Natta catalyzed ultra low density polyethylene having a density of 0.880 g/cm3 to 0.912 g/cm3, a melt index (I2) of 0.5 to 6 g/10 minutes, and a MWD of 6.0 or less, (b) a second layer comprising at least one polyolefin, and (c) at least one inner layer between the first layer and the second layer comprising a high density polyethylene. The film is oriented in the machine direction at a draw ratio of between 4:1 and 10:1, and can exhibit a machine direction 2% secant modulus of 85,000 psi or more when measured as per ASTM D882.
