PURPOSE:To obtain a ultrahigh air-containing and highly self-stretchable string- form object having a stable structure after self-stretching by a method wherein a laminate is composed of a low-temperature shrinking sheet layer, a high- temperature shrinking sheet layer, and two types of adhesive layers. CONSTITUTION:A low-temperature shrinking sheet 1 and a high-temperature shrinking sheet 2 are bonded by adhesive layers 3 and 4 to be laminated, thereby being formed into a string-form object. As the low-temperature shrinking sheet 1, paper of 100mum thickness is used. As the high-temperature shrinking sheet 2, a vinyl chloride shrink film (40mum thick and having a shrinkage factor of 50% laterally and 0% vertically) is used. As the adhesive layers 3, 4, an epoxy adhesive is separately used. The paper and the vinyl chloride shrink film is 10mm long and 20mm wide. The three-layer paper/shrink film/paper laminate bonded through the adhesive layers of 2mm width at both ends is laminated by 16 layers through the adhesive layers of 5mm width at the center. |
