The sheets produced from blends of thermoplastic
starch and poly(lactic acid) had good processability during
molding. The sheets showed good handleability and
homogeneous appearance, without apparent cracks. The
cross-linked chitosan deposited onto sheets homogeneously overlaid the surfaces without changing the
appearance of the sheets, and its presence did not change
the thickness, which was around 0.9-1.2 mm.
