Abstract: The present invention provides multilayer films. In some embodiments, multilayer films of the present invention are desirable for use in thermoforming applications. In one aspect, a multilayer film comprises a first layer comprising polypropylene, polyethylene, or blends thereof, a second layer comprising polypropylene, polyethylene, or blends thereof, and a third layer between the first layer and the second layer, the third layer comprising polypropylene, polyethylene, or blends thereof, wherein at least one of the layers further comprises a cyclic olefin copolymer and wherein the multilayer film comprises at least 1 weight percent and less than 5 weight percent cyclic olefin copolymer based on the total weight of the film.

Abstract: The present disclosure is directed to a fiber that is composed of a polymeric blend including (i) 95 wt % to 99 wt % of a high density ethylene-based polymer having a Mw/Mn from 2.0 to 3.0 and (ii) from 5 wt % to 1 wt % of a low density ethylene-based polymer having a melt index from 5 g/10 min to 15 g/10 min. The fiber has a density from 1 denier to 2 denier and a 3% secant modulus from 8.5 g/denier to 20 g/denier.
