COMPOSTABLE MULTILAYER MATERIAL, POLYMER CORE LAYER COATED ON BOTH SIDES WITH SEMI-CRYSTALLINE ALIPHATIC POLYMER LAYER
摘要
<p>A compostable multilayer film includes a core layer having a first surface and a second surface, a first blocking reducing layer covering the first surface of the core layer, and a second blocking reducing layer covering the second surface of the core layer. The core layer comprises a lactic acid residue-containing polymer having a glass transition temperature (Tg) below 20° C. At least one of the first and second blocking reducing layers comprise a semicrystalline aliphatic polyester. The core layer may be peroxide modified polylactide polymer which exhibits bridging between polylactide polymer chains.</p>
