INVISTA Introduces Polyclear® Conserve™ PET

Packaging Resins that Contain Up To 20 Percent Post-Consumer Recycled PET Content

INVISTA, one of the world’s largest integrated fibers and polymers producers, has formulated Polyclear® Conserve™ PET, a polyester polymer that contains up to 20 percent post-consumer recycled PET and features exceptional color and clarity.

“Polyclear® Conserve™ PET reduces potential contamination issues because it is not a simple blend of reground post-consumer recycled PET flake combined with virgin PET resin,” said Dwight Marshall, marketing manager for INVISTA. “Our process utilizes bottle-grade post-consumer recycled PET flake and reduces it back to its pre-polymer feedstock.  We then repolymerize the polymer so it processes like a virgin PET polymer.”   

Marshall went on to say that INVISTA’s process for producing Polyclear® Conserve™ PET reduces contamination including dirt and other foreign particulates that may be present when recycled PET is sourced from a conventional regrinding process. Polyclear® Conserve™ PET is an extremely high-clarity polymer that is dimensionally stable.

Polyclear® Conserve™ PET is suitable for usage in container applications including bottled water, carbonated soft drinks, juices, sports drinks, teas, food products and household goods and cleaners. This packaging polymer also complies with the Federal Food, Drug and Cosmetic Act for certain food contact applications.

In addition to using Polyclear® Conserve™ PET, many of INVISTA’s customers blend additional post-consumer recycled PET flakes at the point of manufacture and can achieve an even greater loading percentage of recycled PET than would be possible using the combination of virgin PET and post-consumer recycled PET alone.

“Research is ongoing to increase the level of post-consumer recycled PET content in Polyclear® Conserve™ PET,” Marshall said. “At INVISTA, we continue to invest in research and product development to further improve our products’ environmental impact.”

Polyclear® Conserve™ PET can be reclaimed in available PET recycling chains with PET recycling programs and can be reprocessed into the post-consumer PET recycling stream multiple times. For more information about Polyclear® Conserve™ PET, visit www.polymers.INVISTA.com.
