The present invention is suitable for the tear opening is excellent extruding When liquid break property (liquid draining property) extruding nozzle made of a packaging laminate film that improves the reduction in (pouring nozzle), and a packaging pouch for holding stored liquid blood packaging to provide a method of forming the tear yudoheum for opening the packaging laminate film used is a challenge.
In order to solve the above problems, the extruding nozzle of the present invention is a base film layer, the surface side and the packaging laminate of the above three-layer laminated structure comprising a lead-free new sealant layer laminated on the back surface side respectively so as to sandwich the base film layer made of a film, as a pouring nozzle of a film shape having a pouring passage in the central part, displaced by the stretched across the pouring passage, the surface side and the back side at least a lead-free new sealant layer on one side of the base film layer extrusion in the position, it has a tear yudoheum (tear-inducing flaw) by laser beam irradiation.
