| description | In this research, studies on properties of sago starch plastic films with the
additional of various additives, polyvinyl alcohol and silica were carried out. The
additives used in this research were glycerol (GLY), polyethylene glycol (PEG) and
glutaraldehyde (GLU). Glycerol and polyethylene glycol were used as plasticizer to
brittleness, caused by high intermolecular forces. While,
glutaraldehyde was used as crosslinking agent to increase the tensile strength of
films by increasing the cross linking structure. Sago starch plastic films were
prepared through blending process followed by casting method. From the results
obtained, film with the addition of 2 wt% glutaraldehyde shows the highest tensile
strength. Besides that, results showed that the glycerol-plasticized films exhibited
higher elongation at break and tensile strength than that of polyethylene glycolplasticized
films, which mainly due to the better plasticizing effect of glycerol.
Degradability test revealed that the weight loss of unplasticized sago starch plastic
films was lower than of glycerol- and polyethylene glycol-plasticized sago starch
plastic films. The effectiveness of polyvinyl alcohol (PVA) on sago starch plastic
films was studied and compared in the presence of glycerol as plasticizing agent and
glutaraldehyde as crosslinking agent. |
