Agar-based Bioplastic Films as Food Packaging

We have examined the viability of agar-based bioplastics as a substitute for fossil plastic food packaging. Furthermore, we investigated if the addition of cellulose could improve the bioplastic’s properties. The mechanical properties were evaluated through tensile tests. Product safety was assessed with an overall migration test that examined the degradability of the material in hydrophilic, acidic, and fatty foods. The tests showed that the bioplastics tolerated stress comparable to fossil plastics and that the added cellulose improved elasticity. The bioplastics degraded easily in all food simulants. Since these bioplastics are edible, this indicates promising biodegradability and compostability.
