Abstract:
The inventive heat-shrinkable polystyrene film is high in shrinkability in the longitudinal direction that is its main shrinkage direction, is excellent in perforated line openability, and has high toughness. The heat-shrinkable polystyrene film is characterized by particular values with respect to hot-water heat shrinkage ratio in the longitudinal and width directions, right angle tear strength in the width direction, and breaking energies in the longitudinal and width directions.
