    摘要: A method for manufacturing an opening device for a package is disclosed. The opening device comprises an outer wall portion an an inner layer of substantially gas-tight material, the outer wall portion including a first tearing notch defining an opening and a second tearing notch defining a grip tongue, and the outer wall and the inner layer being interconnected substantially over their total surfaces facing each other with the outer wall portion and the inner layer being separated within an area substantially under the grip tongue. The method comprises the steps of coating the inner layer with an adhesion preventing coating within an area corresponding to said grip tongue, and connecting the inner layer to the substantially rigid outer wall portion.
