Abstract: Provided herein are substantially all-poly ethylene films, and in particular blown biaxially oriented all-polyethylene films. The films can be multi-layer, and can be produced using a double bubble process. Particular multi-layer films include at least two skin layers, and al least one core layer disposed directly or indirectly between the at least two skin layers. The film composes: a narrow-composition-distribution metallocene linear low density? polyethylene (narrow-CD mLLDPE), a long-chain-branched metallocene linear low density? polyethylene (LCB mLLDPE), and, optionally, either or both of a low density polyethylene (LDPE) and high density polyethylene (HDPE).

Abstract: Provided herein are films comprising a core layer sandwiched between an outer layer and a scaling layer. The film has a seal initiation temperature at 5 N/15 mm between about 82° C. and about 88° C., a 1% secant modulus m MD between about 300 MPa and about 400 MPa, and plateau seal strength at between about 16 and about 17 N/15 mm. While the outer layer and core layers comprise polyethylene compositions, the sealing layer comprises a polyethylene blend. The polyethylene blend comprises a plastomer and a polyethylene composition in an amount equal to or less than 50 wt %.

Abstract: Disclosed are multilayer films which can provide desired film performance suited for packaging applications favoring cost-effectiveness.

Abstract: Films made from at least two polyethylene polymers differentiated in density, melt index, melt index ratio, or branching index and optionally, with other polymers, are disclosed.

Abstract: Polymeric films are provided. The films comprise an ethylene-derived resin that has a density of about 0.905 to about 0.945 g/cm3, a compositional distribution breadth index (CDBI) of at least 50%, a melt index (MI) of about 0.1 to about 5.0 g/10 min and a branching index (g?) of greater than about 0.7. The film may further comprise a propylene-derived resin having a density of about 0.86 to about 0.91 g/cm3. The films have excellent mechanical and optical properties and double-bubble extrusion processability.
