VTT develops 100% bio-based stand-up pouches

VTT has developed lightweight 100% bio-based stand-up pouches with high technical performance. High performance in both oxygen, grease and mineral oil barrier properties has been reached by using different biobased coatings on paper substrate.
The pouches exploit VTT's patent pending high consistency enzymatic fibrillation of cellulose (HefCel) technology. This technology provides a low-cost method for the production of nanocellulose resulting in a tenfold increase in the solids content of nanocellulose. The densely packed structure of nanocellulose films and coatings enable their outstanding oxygen, grease and mineral oil barrier properties (News Item VTT, 14 March 2017).
