Abstract:
This study is focused on pure poly(lactic acid) type 4042D film and poly(lactic acid) dip-coated film on paper by measuring CO₂ evolution. The study of pure poly(lactic acid) film and poly(lactic acid) dip-coated film on paper by measuring CO₂ evolution. Poly(lactic acid)/paper dip-coated film prepared from poly(lactic acid) in three different dip-coating periods;10, 20 and 40 minutes. The biodegradation was set up by buried test sample in soil within microcosm. The biodegradation of sample was followed over time 0, 1, 3, 5, 7, 14 and 28 days. It was found that pure poly(lactic acid) film has the highest biodegradability at 21.4%. For poly(lactic acid)/paper dip-coated film at 10, 20, and 40 minute dip-coating time that shown biodegradation at 14.6%, 10.9% and 9.6%, respectively.
