ABSTRACT
Biodegradable films of polyvinyl alcohol (PVA) and starch, 60-40 (wt%/wt%) have been prepared by solution casting method. Effect of different cross-linking agents, i.e. glutaraldehyde and formaldehyde withdifferent concentration on the swelling behaviour, porosity and mesh size on these PVA-starch biodegradable films has been studied. The crosslinked films have also been characterised using SEM and FTIR techniques.
