(Photo by VTT)It’s the source of a steady stream of innovations, and now the team at VTT Technical Research Centre of Finland Ltd has developed a new product - a lightweight 100% bio-based stand-up pouch. Offering high performance in both oxygen, grease and mineral oil barrier properties that has been developed by different bio-based coatings on paper substrate. The pouches exploit VTT's patent pending high consistency enzymatic fibrillation of cellulose (HefCel) technology.

"One-third of food produced for human consumption is lost or wasted globally. Packaging with efficient barrier properties is a crucial factor in the reduction of the food loss. Our solution offers an environmentally friendly option for the global packaging industry", says Senior Scientist Jari Vartiainen of VTT.

VTT's HefCel technology provides a low-cost method for the production of nanocellulose resulting in a tenfold increase in the solids content of nanocellulose. Nanocellulose has been shown to be potentially very useful for a number of future technical applications. The densely packed structure of nanocellulose films and coatings enable their outstanding oxygen, grease and mineral oil barrier properties.

HefCel technology exploits industrial enzymes and simple mixing technology as tools to fibrillate cellulose into nanoscale fibrils without the need for high energy consuming process steps. The resulting nanocellulose is in the consistency of 15-25% when traditional nanocellulose production methods result in 1-3% consistency.

However, the development of environmentally friendly new materials is of growing importance. Nanocellulose has been shown to be potentially very useful for a number of future technical applications.

VTT ( @VTTFinland ) has solid expertise in various bio-based raw materials and their application technologies for producing bio-based coatings, films and even multilayered structures both at lab-scale and pilot-scale. A versatile set of piloting facilities are available from raw material sourcing through processing to application testing and demonstration.
