To provide a foamed film or multilayer foamed film excellent in heat insulating properties, a heat shrinkable foamed film or heat shrinkable multilayer foamed film made thereof, a heat shrinkable label, and a container covered therewith. A styrene foamed film characterized by having at least one foamed layer which contains a resin composition comprising from 20 to 100 parts by mass of the following (a) and from 0 to 80 parts by mass of the following (b) and which has a thickness of from 30 to 200 µm and a specific gravity of from 0.3 to 0.9: (a) a block copolymer wherein the ratio of a vinyl aromatic hydrocarbon to a conjugated diene is from 50/50 to 90/10, (b) at least one vinyl aromatic hydrocarbon polymer selected from the following (i) to (v): (i) a block copolymer of a vinyl aromatic hydrocarbon with a conjugated diene, (ii) a vinyl aromatic hydrocarbon polymer, (iii) a copolymer of a vinyl aromatic hydrocarbon with (meth)acrylic acid, (iv) a copolymer of a vinyl aromatic hydrocarbon with a (meth)acrylate, and (v) a rubber-modified styrene polymer. |
