Abstract: PROBLEM TO BE SOLVED: To provide a method for packaging a resin pipe by which the undesirable curling tendency of a crystalline resin pipe is eliminated. SOLUTION: This method for packaging a resin pipe obtained by an extrusion molding process comprises the steps to wind the resin pipe immediately after a molding step around a roll, then maintain this state and cure the resin pipe for a specified period of time and further, and wind the resin pipe around the roll in a reversed winding direction to the direction where the resin pipe is wound around the roll during curing.
