An object of the invention is to provide a heat-shrinkable multi-layer film including a layer formed of a poly(carboxylic acid) polymer (A), a layer formed of a polyvalent metal compound (B), and a heat-shrinkable support film. The invention provides a heat-shrinkable multi-layer film including a heat-shrinkable support film (base film) and, on at least one surface of the base film, at least one layer structure including a layer (a) formed of a poly(carboxylic acid) polymer (A) and a layer (b) formed of a polyvalent metal compound (B), the layers (a) and (b) being in contact with each other, and the multi-layer film exhibiting a percent thermal shrinkage of 3 to 90%. The invention also provides a packaged product obtained by packaging an object with the heat-shrinkable multi-layer film, and a heat-shrinkable label. |
