| abstract |
A compostable multilayer structure is provided by the present invention. The multilayer structure can be in the form of a film, sheet, laminate, and the like, and includes a core layer (12) having a first surface (13) and a second surface (15), a first blocking reducing layer (14) covering the first surface of the core layer, and a second blocking reducing layer (16) covering the second surface of the core layer. The core layer includes a polymer composition of a hydrolyzable polymer containing a lactic acid residue and has a glass transition temperature (Tg) below about 20 deg. C. The first and second blocking reducing layers include a polymer composition of a hydrolyzable polymer and have a Tg above about 50 deg. C. The multilayer structure can be used for preparing bags and wrappers. |
