PROBLEM TO BE SOLVED: To provide a heat-shrinkable polystyrene resin film which is best suited as a packaging material to be used for the covering, binding or exterior- filling of a container or the like and especially, has superb applicability to a heat preservation container and also is best-suited when high-precision printing is performed, and a label and a container using this film. SOLUTION: This heat-shrinkable polystyrene resin film is characterized in that the rate of change in the length of the film after the treatment by applying a load of tension of 51.18 gf for one minute under environments at 110 deg.C, in the main shrinkage direction, to the length before the treatment, is 0 to 90% and the self-shrinkage factor shown in terms of a rate of change in length before and after the film is left alone for one week under temperature conditions at 45 deg.C. |
