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

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

Multilayer films and methods of making the same

Disclosed are multilayer films which can provide desired low-temperature bag drop performance suited for laminate freezer film packaging.
