ABSTRACT:
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 core layer comprises a lactic acid residue-containing polymer having a glass transition temperature (Tg) below 20.degree. C. The first and second blocking reducing layers comprise a semicrystalline aliphatic polyester. The hydrolyzable polymer and have a T.sub.g above about 50.degree. C. The multilayer structure can be used for preparing bags and wrappers.
