SHEET FOR FORMING SLEEVE AND PROCESS FOR PRODUCING THE SAME

摘要

A sleeve and method of making the same comprising a laminate sheet having a more highly shrinkable foamed film and a lesser shrinkable non-foamed film, the ends of the laminate being bonded together so that the foamed film faces the interior of the sleeve. 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.
