ABSTRACT: This review covers the
recent developments in the field of biobased packaging materials. Special
emphasis is placed on the barrier properties, which are crucial in terms of
food packaging. The state-of-the-art of several biopolymers including pectin,
starch, chitosan, xylan, galactoglucomannan, lignin and cellulose nanofibrils
is discussed. As in most cases the packaging related properties of single layer
biopolymer films are inadequate, the thin film coatings, such as sol-gel and
ALD (atomic layer deposition), as well as the multilayer coatings are also
briefly touched.
