摘要： A flexible carrier for carrying a plurality of containers, such as soft drink and other beverage containers, is formed from a polymer composition which provides the carrier with improved elastic recovery following installation of the containers, along with tensile strength and tear resistance. The polymer composition includes about 10% to about 95% by weight of a post-consumer recycled plastic that includes recycled branched low-density polyethylene and recycled linear low-density polyethylene polymers, zero to about 90% by weight of a branched low-density polyethylene polymer having a density of about 0.910 to about 0.950 grams/cm3, and greater than zero to about 65% by weight of an elastomeric ethylene copolymer that includes about 60% by weight to less than 100% by weight ethylene and greater than zero to about 40% by weight of a vinyl acetate comonomer.

摘要： Disclosed herein are ethylene-based polymers generally characterized by a melt index of less than 15 g/10 min, a density from 0.91 to 0.945 g/cm3, a CY-a parameter at 190 °C from 0.2 to 0.6, an average number of long chain branches per 1,000,000 total carbon atoms of the polymer in a molecular weight range of 500,000 to 2,000,000 g/mol of less than 5, and a maximum ratio of ηE/3η at an extensional rate of 0.03 sec-1 in a range from 3 to 15. The ethylene polymers have substantially no long chain branching in the high molecular weight fraction of the polymer, but instead have significant long chain branching in the lower molecular weight fraction, such that polymer melt strength and bubble stability are maintained for the fabrication of blown films and other articles of manufacture. These ethylene polymers can be produced using a dual catalyst system containing a single atom bridged metallocene compound with an indenyl group and a cyclopentadienyl group, and an unbridged hafnium metallocene compound with two cyclopentadienyl groups.
