Abstract
A method of producing a gable-top paper or paper-board based packaging container is disclosed, the packaging container having a plurality of top-closure sub-panels, including a top-closure sub-panel () configured to form a pouring spout of the packaging container when the packaging container is in an open position, the top-closure sub-panel being configured to form a pouring spout comprising top-fin panel sections () being at least partially hot-sealed to each other prior to a first opening of the packaging container, the top-fin panel sections abutting one another in a contact region when the packaging container is in a closed position. The method comprises the steps of: producing a blank () from a laminate packaging material having an outside heat sealable layer; and treating the outside heat sealable layer in a sub-region () of at least one of said top-fin panel sections () reducing or eliminating the heat-sealing capacity of the outside heat sealable layer in the sub-region. A related blank and a packaging container produced from such a blank is also disclosed.
