New Biobased Label Adhesive for PET Recycling

WILMINGTON, DE—June 7, 2012—Susterra® Propanediol from DuPont Tate & Lyle Bio Products was selected as a key renewable building block in a new biobased label adhesive. DaniMer Scientific, LLC is releasing a new biobased label adhesive, designated DaniMer 92721, to eliminate the problems associated with polyethylene terephthalate (PET) container recycling. To develop the adhesive, DaniMer utilized renewable building blocks from two world-class suppliers: DuPont Tate & Lyle BioProducts, and Myriant. DaniMer combines Susterra® propanediol from DuPont Tate & Lyle, and bio-succinic acid from Myriant into a proprietary, patent-pending resin that enables the breakthrough properties of the new 92721 label adhesive.

DaniMer’s new label adhesive is designed to meet the stringent demands of the PET container and packaging recycling streams while offering the additional benefit of a renewable content higher than 50 percent. The DaniMer adhesive dissolves completely in the PET flake caustic wash recycling operations without clumps or “stickies.” This new biobased formulation is competitively priced with block co-polymers, with pricing not linked to crude oil derivatives. In addition, rheology of DaniMer 92721 enables the adhesive to operate in existing adhesive systems at temperatures under 325 degrees F. Results from industry standard protocol testing show the product enables zero contamination in PET recycle streams.

“DaniMer is pleased to announce this advancement toward eliminating a significant challenge within the PET recycling process,” said Daniel Carraway, CEO of DaniMer Scientific. “We have been actively engaged with our customer partners in order to best understand the PET recycling processing challenges. The issue of contamination by the label adhesive was a recurring problem and if resolved provided a significant quality improvement for the users of recycled PET. Our objective of providing world class solutions, led us to choose DuPont Tate & Lyle along with Myriant as our primary suppliers for this project due to their innovative capabilities, knowledge and extensive background with the development of renewable building blocks.”

“Susterra® propanediol is certified 100 percent biobased by the U.S. Department of Agriculture, making it attractive for companies seeking to add renewable content to their products. We are excited to be selected by DaniMer as a key ingredient for this new biobased adhesive technology.” commented Pete Colombo, account executive for DuPont Tate & Lyle Bio Products.

DaniMer Scientific will be providing details and describing the commercial launch of their new label adhesive at the Nova-Pack 2012 Conference in Arlington, VA. The product exhibition will be on June 7-8 at West Arlington Gateway Hotel, just outside of Washington, D.C. The exhibition gives packaging suppliers and users a chance to display products they designed that overcome challenges faced with the PET recycling industry.
