发明名称 ANORDNING VID FORPACKNINGSBEHALLARE
摘要 An arrangement on packing containers of flexible packing material, this arrangement making possible a tight closing and simple opening of the top part of the packing container. In, for example, a gable-top package (1) the arrangement comprises a sealing film (8) projecting outside the top edge of the packing container material, which after conventional shaping of the top part of the packing container is sealed in a sealing zone (9) and is provided with a projecting tearing strip (11). The film (8) is a laminate sealable to the packing material with a suitable barrier layer, e.g. Al-foil, and, owing to its small thickness, can be simply sealed in a gas-tight manner to itself as to the inside of the packing material.
