The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment is composed of a polymeric composition. The polymeric composition includes (i) from 70 to 90 weight percent of a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.970 g/cc, a melt temperature, Tm, greater than 125&#xb0; C., and a melt index from 1 g/10 min to 50 g/10 min; and (ii) from 30 to 10 weight percent of an olefin-based elastomer having a density from 0.860 g/cc to 0.905 g/cc, a melt index from 0.2 g/10 min to 50 g/10 min, and a Tm less than 125&#xb0; C.

Fitment with blend component and flexible container with same

A molded article formed from a polymer composition, the polymer composition consisting essentially of: an ethylene homopolymer or ethylene/alpha-olefin copolymer; greater than 20 ppm of a fluoropolymer; and optionally, up to 5 wt. % of one or more of processing aids, acid neutralizers, stabilizers, phosphites, antioxidants, metal de-activators, pigments or colorants, or fillers; wherein the molded article exhibits an oxygen transmission rate [OTR, (cc*mm)/(m*day*atm)]&#x2264;&#x2212;3181 (cc*mm)/g*m*day*atm)&#xd7;[Density, g/cc]+3077, (cc*mm)/(m*day*atm).

Molded articles and methods thereof

Ethylene-based interpolymers, e.g., ethylene-acrylic acid copolymers, are made by a process comprising the steps of: A. Injecting a first feed comprising a chain transfer agent system (CTA system) and ethylene into a first autoclave reactor zone to produce a first zone reaction product, the CTA system of the first reactor zone having a transfer activity Z1; and B. (1) Transferring at least part of the first zone reaction product to a second reactor zone selected from a second autoclave reactor zone or a tubular reactor zone, and (2) at least one of transferring or freshly injecting a feed comprising a CTA system into the second reactor zone to produce a second zone reaction product, the CTA system of the second reactor zone having a transfer activity of Z2; and with the proviso that the ratio of Z1:Z2 is greater than 1. The comonomer comprises at least one carboxylic acid group or an anhydride group.
