摘要
A method of manufacturing heat shrinkable tubing having one portion thereof in the form of a single tube and the remaining portion thereof in the form of plural tubes. The heat shrinkable tubing is manufactured by extruding a thermoplastic tube and then longitudinally sealing the tube periodically with applied pressure while the tube is heated to form predetermined plural tube lengths. The tube is then subjected to irradiation, heated to at least the softening temperature of the material of the tube and it is then partially inflated and thermoset by cooling to impart heat shrinkable properties to the tube. The heat shrinkable tube so formed is then periodically cut to form a plurality of heat shrinkable tube sections which each consist of a single tube portion and a remaining plural tube portion.
