PURPOSE: An environmentally-friendly and decomposable multi-layer film is provided to maintain transparency and supplement heat resistance and anti-blocking property. CONSTITUTION: An environmentally-friendly and decomposable multi-layer film comprises a first resin layer and a second resin layer. The first resin layer includes an aliphatic polycarbonate resin. The aliphatic polycarbonate resin can be obtained by polymerizing epoxide compound which is selected from a group consisting of alkylene oxide, cycloalkene oxide, and a mixture thereof and carbon dioxide. The aliphatic polycarbonate resin is selected from a group including polyethylene carbonates, polypropylene carbonate, and a mixture thereof. The aliphatic polycarbonate resin has a number average molecular weight of 50,000-1,000,000. |
