An object of the present invention is to provide a heat-shrinkable film that has a low environmental impact, has excellent heat-shrinkage properties, impact resistance, transparency, mechanical properties, and shrink-finishing properties, and is suitable for applications such as shrink-wrapping, shrink-bound packaging, and shrink labels. Get. A polylactic acid-based resin and a polyolefin-based resin are contained as main components, and a mass ratio of the polylactic acid-based resin to the polyolefin-based resin is 95/5 to 50/50. The lactic acid resin is a copolymer of D-lactic acid and L-lactic acid or a mixed resin of this copolymer, and the D / L ratio of D-lactic acid and L-lactic acid is 3/97 to 15/85 or 85/15 to 97/3, the storage elastic modulus (E ′) at 20 ° C. measured at a vibration frequency of 10 Hz and a strain of 0.1% of the polyolefin resin is 100 MPa or less, and stretched in at least one direction And the heat shrinkage rate in the main shrinkage direction of the film when immersed in warm water at 80 ° C. for 10 seconds is 20% or more.
