Generally, a heat-shrinkable tube is a tube, such as a synthetic resin, which shrinks in the entire area when exposed to heat, and is used to protect or fix terminals, cables or components inserted therein. Further, the heat-shrinkable tube is formed into a cylindrical shape without a joint, and is made of a material such as polyolefin, Teflon, or PVC having a property of shrinking by heat. Therefore, when heat is applied to the heat-shrinkable tube, the heat-shrinkable tube is shrunk so that the inner circumferential surface is brought into close contact with the cable or the like inserted therein, thereby fixing the cable or the like and protecting it from the outside.

As a conventional heat-shrinkable tube, a heat-shrinkable tube for insulation is a heat-shrinkable shield tube of Korean Patent No. 10-0212421 and a method for manufacturing the same, which includes an outer tube including a heat-shrinkable material and an inner circumference of the tube An inner shielding layer made of a woven or nonwoven fabric for shielding electromagnetic waves, and an adhesive for attaching the woven or nonwoven fabric to the inner surface of the tube.

Conventional heat-shrinkable tubes are used for display purposes in addition to the above-mentioned insulation and component protection. For example, although a cable must be installed intrinsically safe type, a heat-shrinkable tube may be erroneously installed or changed with a normal type cable , A blue heat-shrinkable tube is installed at both ends of such a normal type cable.

However, when a blue heat-shrinkable tube for display is to be installed on such a normal type cable, when the normal type cable is already connected, there is a problem in that it takes a lot of time and inconvenience by unscrewing all the wires and installing a heat-shrinkable tube. In addition, the heat shrinkable tubes have different thicknesses depending on the thickness of the cable on which the heat shrinkable tubes are installed.

These problems can be similarly applied to heat-shrinkable tubes for insulation or parts protection.
