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 film, preferably, a multi-layered film, including a polymer composition, wherein the polymer composition includes: within a range from 1 wt % to 25 wt % of a cyclic olefin copolymer based on the weight of the polymer composition, and within a range from 75 wt % to 99 wt % (the remainder of material) of a polyethylene based on the weight of the polymer composition, wherein the cyclic olefin copolymer has a glass transition temperature (T.sub.g) of at least 80.degree. C. The films may be used in shrink packaging application.

Polyethylene films and methods of making the same

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

Polyethylene films

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