    Abstract: A process for separating and recovering at least one polymer component from a melt of a multiple number of polymer components including the steps of: (A) shearing a multi-polymer component melt in the presence of a pressurized aqueous solution; wherein the multi-polymer component melt comprises a blend of at least a first polymer component and at least a second polymer component; wherein the multi-polymer component melt has at least two melting temperatures, at least two glass transition temperatures or combinations thereof; wherein the pressurized aqueous solution comprises an aqueous liquid mixture of: (i) water, and (ii) at least one dispersing agent; wherein the shearing of the multi-polymer component melt in contact with the pressurized aqueous solution forms a dispersion, particles, or strands of the at least one first polymer component having an enriched first polymer component concentration; and (B) after the shearing of step (A), isolating the at least first polymer component from the other polymer components of the multi-polymer component melt by separating the dispersion, particles, or strands of the at least one first polymer component having an enriched first polymer component concentration from the water, the at least one dispersing agent, the at least second polymer component, and any remaining thermoplastic polymer resins present in the mixture of the multi-polymer component melt in the pressurized aqueous solution.

    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: A system and method for performing a tear test are described herein. The system may include a fixed clamping station configured to hold a first portion of a film specimen and a movable clamp coupled to an actuator, the movable clamp may be configured to hold a second portion of the film specimen. The movable clamp may be configured to move in a direction away from the fixed clamping station to tear the film specimen. The system may include a slitter blade configured to cut the film specimen at a location between the fixed clamping station and the movable clamp. The system may include a load cell coupled to one of the fixed clamping station and the movable clamp. The load cell may be configured to measure a force associated with tearing of the film specimen. The actuator may be configured to manipulate the movable clamp along a trajectory.
