Packing containers and packing container blanks of the type used for the packaging of, e.g., milk and juice, often are of the so-called gable-top type, in which the top closure also serves as an opening arrangment with a pouring spout which can be folded outwardly. The parts of the packing container or the blank forming the pouring spout may be partially coated with a seal-preventing substance to make it possible for the pouring spout to be detached and opened outwardly in spite of the heat-sealing of the top. The seal-preventing coating in accordance with the invention is covered by a film which extends along the upper edge region of the packing container to provide a better defined sealing strength, a tighter top seal, and protection to the coating both before and after the conversion of the packing container blank to packing containers.
