ABSTRACT:
In some preferred embodiments, a heat shrinkable foamed sheet has a foamed layer (2) constituting a core layer, and a non-foamed layer (3) constituting a surface skin layer integrally formed on the formed layer. The non-foamed layer (3) is less than about 1.55 μm in maximum surface smoothness measured in accordance with ISO8791-4. Alternatively, by regulating various dimensions of foam cells formed in the foamed layer (2) so as to fall within predetermined ranges, a heat shrinkable foamed sheet excellent in surface smoothness and printing nature can be obtained.
