PROBLEM TO BE SOLVED: To provide a heat-shrinkable polystyrene-based resin film suitable as a packaging material used for covering, bundling, exterior, etc. of containers and the like, especially a low shrinkage appropriate temperature range, aseptic filling packaging and the like. A heat-shrinkable polystyrene resin film having excellent applicability to packaging in a short time, and a label and a container using the same. SOLUTION: The heat shrinkage as indicated by the rate of change in length after the immersion for 10 seconds in hot water at a temperature of 65 ° C. in the main shrinkage direction with respect to before the treatment is 5% or more, and the temperature in the main shrinkage direction is 110%. A heat-shrinkable polystyrene-based resin having a rate of change in length from 0% to 90% with respect to the length before the treatment after a treatment of applying a tension of 51.18 gf for 1 minute in an environment of 0 ° C. the film. |
