Danimer's bio-adhesive for bio-PET

The use of bio-based polyethylene terephthalate (PET) containers is getting another boost with this announcement from DaniMer Scientific.
FYI, DaniMer's sister company Meredian, by the way, is a producer of polyhydroxyalkanoate (PHA) polymers.
DaniMer said that it has partnered with DuPont Tate & Lyle for the use of its bio-based propanediol (PDO) Susterrra, and Myriant for the use of its bio-succinic acid, in the development of a bio-based label adhesive.
The adhesive, under the line DaniMer 92721, was created to eliminate the problems associated with PET container recycling, according to DaniMer. The adhesive, with a more than 50% renewable content, dissolves completely in PET flake caustic wash recycling operations "without clumps or stickies."
"This new bio-based 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 deg F. Results from industry standard protocol testing show the product enables zero contamination in PET recycle streams."
DaniMer said it will provide details and announce the commercial launch of their new label adhesive at the Nova-Pack 2012 Conference in Arlington, Virginia, which is being held today and tomorrow at West Arlington Gateway Hotel.

DaniMer recently announced its entrance into the Czech Republic market with a partnership deal with Standridge Color Corporation. The company is expected to produce DaniMer's PHA plastics at Standridge's Czech plant earlier this year, according to Plastics News.
