More Information
Summary:The present disclosure provides embodiments of a composition comprising post-consumer recycled resin comprising: at least 50 weight percent polyolefin, having an initial limonene level of at least 5 ppm; virgin ethylene-based polymer; and at least one odor-active zeolite, wherein the odor-active zeolite has an FAU crystal structure, an MFI crystal structure, and/or a beta crystal structure and a Si/Al molar ratio from 1 to 100, wherein the composition has a reduced limonene level of less than 3 ppm. The present disclosure also provides embodiments of a method of reducing taste and/or odor in a post-consumer recycled (PCR) resin-containing composition.
