Abstract

PURPOSE:To obtain a cylinder wall excellent in sealing property, gas-shielding property and light-shading property, by thermally contracting a biaxially-elongated heat-contracting synthetic resin cylinder piece with a forming core to form a cylinder body, and transferring and welding a synthetic resin sheet provided with an aluminum foil layer onto the periphery of the cylinder body. CONSTITUTION:A cylindric parison from an extruder is cooled, biaxially elongated into a cylindric body. This cylindric body is cut into cylinder pieces 2 having a fixed length. The cylinder piece 2 is assembled in a forming core 13, and formed into a cylinder body 3 having a desired shape with use of heat contraction. Onto the whole periphery of the cylinder body 3 is transferred and welded a laminate sheet 5, which was fromed by laminating and welding the outside layer 7 of a synthetic resin film onto at least the outside sutface of an aluminum foil 6. Thus, a cylinder wall 4 is obtained.
