Abstract

PURPOSE:To manufcture heat-shrinkable composite tube or film generating wrinkle like unevenness in heating by laminating and stretching synthetic resin becoming heat-shrinkable by stretch and synthetic resin hardly heat-shrinkable. CONSTITUTION:Synthetic resin A presenting heat-shrinking property by strech and synthetic resin B hardlypresenting heat-shrinking property are laminated in tube or film so as thickness ratio of the resin A layer and the resin B layer is 1:0.05-1:0.25. And the laminate is stretched at the stretch temperature proper to stretching of synthetic resin A. By this, the heat-shrinkable composite tube or film is obtained, which can offer the covered article having slip-proof, supple touch and cushioning properties by generation of wrinkle like unevenness when heated.
