PROBLEM TO BE SOLVED: To provide a polylactic acid-based mulching film having excellent flexibility, heat resistance, bleed-out resistance and durability, and further superior resistance to shrinkage with time, tear propagation resistance and total light transmittance necessary as a mulching film, while containing a large amount of filler.SOLUTION: The polylactic acid-based mulching film comprises a polylactic acid-based resin as a resin (A), a thermoplastic resin other than the polylactic acid-based resin as a resin (B), and a compound treated with a surface treatment agent as a filler (C), and is formed from a composition containing the resin (A) in an amount of 30-70 mass% and the resin (B) in an amount of 30-70 mass%, each based on 100 mass% of the total of the resins (A) and (B), and the filler (C) in an amount of 20-100 pts.mass to 100 pts.mass of the total of the resins (A) and (B). |
