PROBLEM TO BE SOLVED: To provide a heat shrinkable white film which has heat shrinkability, white color and high concealability, high surface smoothness, and can be easily obtained.SOLUTION: The heat shrinkable white film contains amorphous polyethylene terephthalate, a cyclic olefin resin having a glass transition temperature of 100°C or more and a polyester elastomer having a Vicat softening point of 130°C or less. In the heat shrinkable white film, the content ratio of the amorphous polyethylene terephthalate is 55 to 70 mass%, the content ratio of the cyclic olefin resin is 20 to 30 mass% and the content ratio of the polyester elastomer is 5 to 15 mass%, based on 100 mass% of the total of the amorphous polyethylene terephthalate, the cyclic olefin resin and the polyester elastomer, and the heat shrinkable white film has a single layer. |
