Abstract
A heat-shrinkable sheet made of a foamed thermoplastic resin having a number of cells and which is adapted to cover a fragile container such as a glass bottle, is heat-shrunk so that said sheet can stick to the container. The cells of the sheet are burst, i.e., opened or collapsed, so that the surface of the sheet which contacts the surface of a container is formed in a convexo-concave surface, which facilitates the entry of boiling water or cooling water between the sheet and the surface of the container when the sheet is adhered to the container.
