New bio-based packaging materials are
highly interesting for replacing conventional fossil
based products for a more sustainable society. Waterstable
cellulose fiber foams have been produced in a
simple one-batch foam-forming process with drying
under ambient conditions. The cellulose fiber foams
have a low density (33–66 kg/m3) and can inhibit
microbial growth; two highly valuable features for
insulating packaging materials, especially in combination
with stability in water. Cationic chitosan and/or
polyvinylamine have been added during the foamforming
process to give the foams water-stability and
antimicrobial properties. The structural and mechanical
properties of the cellulose fiber foams have been
studied and the antimicrobial properties have been
evaluated with respect to both Escherichia coli, a
common model bacteria and Aspergillus brasiliensis,
a sporulating mold. The cellulose foams containing
chitosan had both good water-stability and good
antibacterial and antifungal properties, while the
foams containing PVAm did disintegrate in water
and did not inhibit fungal growth when nutrients were
added to the foam, showing that it is possible to
produce a bio-based foam material with the desired
characters. This can be an interesting low-density
packaging material for protection from both mechanical
and microbial damage without using any toxic
compounds.
