A new biobased label adhesive, DaniMer 92721, can reportedly eliminate the problems associated with polyethylene terephthalate (PET) container recycling. To develop the adhesive, DaniMer used renewable building blocks from Dupont Tate & Lyle and Myriant.
The new label adhesive is designed to meet the demands of PET container packaging recycling streams and has a renewable content higher than 50%. It reportedly dissolves completely in PET flake caustic wash recycling operations without clumps or “stickies.” This new bio-based formulation is reportedly competitively priced with block copolymers, with pricing not linked to crude oil derivatives.
