Many companies are building the value of their brands<br />
and growing their business by investing in development<br />
of product offerings that utilize renewable-based<br />
biopolymer materials. DaniMer Scientific, LLC is enabling brand<br />
owners and converters who focus on environmental stewardship<br />
to grow their market share by offering biopolymers for extrusion<br />
coating of paper and paperboard. Extrusion coating is an excellent<br />
application for biopolymers, and there is no current opposition<br />
concerning contamination of the existing recycle stream for<br />
paper articles when biopolymers are present. Further enhancing<br />
its appeal, DaniMer’s extrusion coating resin provides additional<br />
value by enabling coated articles to be repulpable. DaniMer’s advances<br />
in the use of biopolymers led to the introduction in 2006<br />
of the world’s first commercial extrusion coating resin that meets<br />
global standards for compostability while utilizing renewable resources.<br />
This new DaniMer technology enabled International Paper<br />
to launch the Ecotainer product in a partnership with Green<br />
Mountain Coffee. Since that launch, DaniMer’s extrusion coating<br />
product has continued to enjoy the market’s embrace and<br />
steady growth. In fact, International Paper recently announced it<br />
has crossed the one billion cup milestone and is expanding their<br />
product line to include cold cups for a certain large global brand<br />
owner; further demonstrating that biopolymer coated paper substrates<br />
are more than just a fad. DaniMer has expanded its customer<br />
base and is working with key customers on a global basis<br />
in various stages of commercialization for new products.<br />
DaniMer’s proprietary extrusion coating resin is based on<br />
NatureWorks Ingeo Biopolymer. Ingeo biopolymer is an excellent<br />
material, but requires modification for melt strength, melt curtain<br />
stability, and adhesion to paper in extrusion coating applications.<br />
In most cases, DaniMer’s extrusion coating resin can be run on<br />
existing equipment with minimal adjustments relative to the<br />
