An injection molded cap or closure having a weld line, wherein the injection molded cap or closure is formed from an ethylene-based resin comprising a high molecular weight component and a low molecular weight component.

Injection molded caps or closures, and methods thereof

Polyethylene formulations and articles produced therefrom, comprise a multimodal high density polyethylene (HDPE) composition, and 0.1 ppm to 300 ppm of a nucleating agent, wherein the multimodal HDPE composition comprises a density of 0.940 g/cmto 0.970 g/cmwhen measured according to ASTM D792, and a melt index (I2) of 0.1 g/10 min. to 10.0 g/10 min. when measured according to ASTM D1238 at 190&#xb0; C. and a 2.16 kg load, and wherein the multimodal HDPE composition comprises an infrared cumulative detector fraction (CDF) of greater than 0.27 and an infrared cumulative detector fraction to light scattering cumulative detector fraction ratio (CDF/CDF) from 0.7 to 2.0.

Polyethylene formulations with improved barrier and environmental stress crack resistance

Polyethylene formulations, articles produced therefrom, and methods of making articles are provided. The polyethylene formulation includes a multimodal high density polyethylene (HDPE) composition, and 1 ppm to 10,000 ppm of a nucleating agent, wherein the multimodal HDPE composition comprises a density of 0.940 g/cmto 0.970 g/cmwhen measured according to ASTM D792, and a melt index (I) of 0.01 g/10 min. to 1.0 g/10 min. when measured according to ASTM D1238 at 190&#xb0; C. and a 2.16 kg load, and wherein the multimodal HDPE composition comprises an infrared cumulative detector fraction (CDF) of greater than 0.27 and an infrared cumulative detector fraction to light scattering cumulative detector fraction ratio (CDF/CDF) from 0.7 to 2.0.

Polyethylene formulations with improved barrier and toughness for molding applications

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

A method for processing a thermoplastic material that comprises a microwave-sensitive polymeric region, wherein the method includes exposing the microwave-sensitive polymeric region to microwaves; wherein the exposing results in an increase in the temperature of the polymeric region; and processing the thermoplastic material is disclosed.
