Abstract
A pouring nozzle is made from a packaging laminate film which is excellent in the tear-opening property and improves lowering of a liquid draining property in pouring. A method forms a tear-inducing flaw for opening a packaging laminate film suitable for use in a package bag for housing and keeping a liquid packed material. A pouring nozzle is made from a packaging laminate film having a laminate structure of not less than three layers including a base film layer and non-oriented sealant layers laminated on front and rear surface sides of the base film layer and having a pouring path at its central portion. A tear-inducing flaw is formed by irradiating a laser beam across the pouring path and to a position where a portion of at least one of the non-oriented sealant layers on the front and rear surface sides of the base film layer is displaced by pushing.
