The foamed film has a thicker surface layer on its side opposite that laminated to the non-foamed layer, which therefore faces the interior of the sleeve.The flow direction shrinkage rate of the laminated sheet, which is 60% or less, is greater than the widthwise shrinkage rate of the laminated film. The widthwise shrinkage rate is 10% or less. | |
