Fig. 1 is a perspective view of a winding tube according to a first embodiment of the present invention, and the winding tube is generally indicated by a reference numeral 10. The wound tube 10 includes an outer layer 11 and an inner layer 12. The outer layer 11 is formed of black PE as the first material, and the inner layer 12 is preferably formed of yellow PE as the second material in order to facilitate inspection of the inner wall of the wound tube in the future. The color of the inner layer 12 is not limited to yellow, and may be gray, white, light color, bright color, color different from the first material, or other colors. If there is no need to inspect the inner wall of the wound tube in the future, the inner layer of the wound tube can be made to have the same color or other dark color as the outer layer. Preferably, the second material forming the inner layer 10 is preferably mixed with an antibacterial agent or nano silver particles so that the inner layer 10 of the wound tube 10 has functions such as resistance to bacteria, bacteriostasis -04201245, and the like.
