    Abstract: Embodiments of the present disclosure are directed to post-consumer recycled (PCR) resin formulations comprising: PCR resin comprising a blend of polyethylene recovered from post-consumer material, pre-consumer material, or combinations thereof; and virgin polyethylene resin formulation, wherein the virgin polyethylene resin formulation comprises: a density from 0.910 to 0.950 g/cc, an improved comonomer content distribution (iCCD) wt. fraction greater than 30 wt. % at a temperature range of 35 to 90° C., and an iCCD wt. fraction greater than 8 wt. % at a temperature range of 99 to 115° C. The PCR resin formulation comprises an overall density of from 0.910 to 0.930 g/cc; an iCCD second elution peak occurring at a temperature greater than 99° C.; an iCCD wt. fraction greater than 6 wt. % at a temperature range of 99 to 115° C.; and an iCCD wt. fraction greater than 60 wt. % at a temperature range of 35 to 90° C.

    Abstract: Provided are multilayer films including ethylene-based polymers. The multilayer films can be fully compatible with polyethylene recycling streams. The multilayer films include a first outer layer, a second outer layer, and a core, the core including a first core layer that includes an ethyl ene-propylene copolymer. The multilayer films of the present invention can exhibit improved, maintained, or desirable properties, such as high tear resistance, in comparison to existing multilayer film structures that are not fully compatible with polyethylene recycling streams.

    Abstract: A process comprising forming fibers having at least a first region and a second region wherein the first region comprises an ethylene/alpha olefin interpolymer composition characterized by: density in the range of 0.930 to 0.965 g/cm3; melt index (I2) in the range of from 10 to 60 g/10 minutes; molecular weight distribution in the range of from 1.5 to 2.6; tan delta at 1 radian/second of at least 45; a low temperature peak and a high temperature peak on an elution profile via improved comonomer composition distribution (ICCD) procedure; and full width at half maximum of the high temperature peak is less than 6.0° C. and stretching the fibers to an elongation of at least 20% thereby increasing curl of the fiber. The process may further include forming a non-woven from the fibers and the stretching of the fibers may occur before or after forming of the non-woven.

    Abstract: Provided are bicomponent fibers with curvature. The bicomponent fiber includes a first region and a second region. The first region includes a polypropylene blend and second region includes an ethylene/alpha-olefin interpolymer composition. The polypropylene blend includes a polypropylene homopolymer and a propylene-ethylene interpolymer, wherein the propylene-ethylene interpolymer has a density of from 0.860 to 0.880 g/cc and a melt flow rate of greater than 12 g/10 min. The ethylene/alpha-olefin interpolymer composition has a density of greater than 0.920 g/cc and a melt index (I2) of from 10 to 25 g/10 min. The bicomponent fiber can be used to form a nonwoven.
