Abstract
The present invention provides a heat shrinkable film that has excellent heat shrinkability while preventing contamination in subsequent processes such as printing. The present invention relates to a heat shrinkable film that at least includes a front layer and/or a back layer. The front layer and the back layer each contain a cyclic olefin resin in an amount of 55 to 99.99% by weight and organic fine particles in an amount of 0.01 to 0.3% by weight.
