<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a tubular body which is free from a blocking phenomenon between films and has both end parts of the films to be bonded together in an extremely short time after applying an adhesive to the both end parts, when the tubular body is manufactured using a self-stretching polyethylene film. SOLUTION: This method for manufacturing a tubular body is to mold a polyethylene film 2 which is self-shrinkable and subjected to a corona discharge treatment over one surface 2a and is printed, in a cylindrical form to obtain the tubular body. In addition, the method comprises a step to apply an adhesive 3 of 2-cyanoacrylate to the end part 5 of the one surface 2a of the film 2 along the longitudinal side of the film 2 and an adhesion step to form the film 2 in a cylindrical shape and adhesively laminate its both end parts 5, 6 as a solution for the formation of the tubular body.</p> |
