摘要
PURPOSE: A polylactic acid resin and a packing film including thereof are provided to enhance mechanical property, heat resistance, flexibility, stiffness, transparency, and blocking resistance.;CONSTITUTION: A polylactic acid resin comprises a hard segment including polylactic acid recurring units which are represented by chemical formula 1 and soft segment including polyurethane polyol recurring unit which is linearly connected with polyether-based polyol repeating units which are represented by chemical formula 2. A chemical formula 3 satisfies the following relation: 75,000=((W L/144.125) / (W P/M Wp))*144.125+M Wp = 220,000. In the chemical formula 1 and 2, A is C2-5 linear or branched alkylene group, m is an integer 10-100, and n is an integer of 700-5000.;COPYRIGHT KIPO 2012
