Provided herein are monolayer films, and also multilayer films comprising a core, a subskin disposed on the core, and a skin disposed on the subskin. The films may have an Elmendorf tear in MD greater than about 7.0 g/μm, a dart impact greater than about 6.0 g/μm, and a 1% secant modulus greater than about 200 MPa. In multilayer films, the core comprises a first polyethylene blend comprising an ethylene 1-hexene copolymer and a high density polyethylene composition in an amount between about 0 wt. % and about 40 wt. %. Further provided herein are bags and laminates comprising the present films.

Films made of polyethylene blends for improved bending stiffness and high MD tear resistance

A multi-layered polyethylene film suitable for shrink applications including at least a core layer and at least one other layer adjacent thereto, the core layer including within a range from 5 wt % to 50 wt % of a cyclic olefin copolymer based on the weight of the core layer, and within a range from 50 wt % to 95 wt % of a polyethylene based on the weight of the core layer, wherein the cyclic olefin copolymer has a glass transition temperature (T) of at least 70&#xb0; C.

Shrink films comprising a cyclic-olefin copolymer core

Disclosed are multilayer films which can provide balanced improvement in film mechanical performance, where the film comprises a propylene-based polymer and an elastic ethylene copolymer.

Multilayer films and methods of making the same

Disclosed are multilayer films with high toughness performance, where the films have an elastic ethylene copolymer in the core layer.

Films made from metallocene-catalyzed polyethylene polymers, optionally, with other polymers, are disclosed.

Polyethylene films

Disclosed are methods for making a multilayer blown film comprising a propylene-based elastomer in the skin and/or subskin layers.

Low crystalline polypropylene-based polymer for blown film applications

Disclosed are multilayer films which can provide desired film performance and balanced overall performance suited for various applications.

The present disclosure relates to compositions comprising a propylene-based elastomer, a branched polymer, and a blowing agent. The present disclosure also relates to foamed layers and articles made from such layers.

Compositions comprising propylene-based elastomers, foamed layers made therefrom, and methods of making the same

Provided herein is a polymer comprising greater than or equal to about 70 wt % units derived from ethylene, less than or equal to about 30 wt % units derived from propylene, and less than about 5 wt % of units derived from C-Calpha-olefins, and having the following properties: crystallinity derived from ethylene; a heat of fusion of about 20 to about 85 J/g; a polydispersity index (Mw/Mn) of less than about 2.5; a reactivity ratio of about 0.5 to about 1.5; a proportion of inversely inserted propylene units based on 2, 1 insertion of propylene monomer in all propylene insertions, as measured byC NMR of less than 0.5 wt %; and a branching index greater than about 0.5
