摘要: A packaging container made of plastic has a fixed wall part (W1), produced by injection molding, and a detachable wall part (W2), which are connected by a predetermined breaking zone (20). The predetermined breaking zone (20) is covered by a barrier layer (24) which provides enhanced barrier action against gases, water vapor or solvent. The barrier layer (24) reduces the permeability of the predetermined breaking zone (20).
