Printing Cylinders at Different Angles, and a Prototype of An Innovative Packaging Material

Caption

The top images show how the researchers are able to precisely control the orientation of the cellulose nanofibrils, printing in different directions in the same way that natural wood grows. The lower images show a honeycomb structure with solid particles encapsulated in the air gaps between the printed walls. Cellulose has excellent oxygen barrier properties, meaning this could be a promising method for creating airtight packaging, for foodstuffs or pharmaceuticals for example.
