<p>PROBLEM TO BE SOLVED: To provide a film capable of being formed by an inflation molding machine, keeping biodegradability and showing excellent weatherability and flexibility by combining various biodegradable resins. SOLUTION: A biodegradable film is manufactured by an inflation-molding machine using a biodegradable resin composition obtained by compounding 20 to 82 wt.% of an aliphatic aromatic polyester having a melting point of 105 to 115 deg.C obtained by condensing a dicarboxylic acid component comprised of an aliphatic dicarboxylic acid and an aromatic dicarboxylic acid and a diol component comprised of an aliphatic diol and polymerizing the obtained aliphatic aromatic polyester with a polyfunctional isocyanate and 18 to 80 wt.% of an aliphatic polyester-based resin having a melting point of 110 to 120 deg.C obtained by condensing a dicarboxylic acid component comprised of an aliphatic dicarboxylic acid and a diol component comprised of an aliphatic diol and polymerizing the obtained aliphatic polyester with a polyfunctional isocyanate.</p> |
