摘要： A packaging container comprises a foil laminate comprising at least two layers in which openings are formed. The two layers are joined together over their entire surface area, except for in a striplike channel. A valve strip is disposed in the channel and in valvelike fashion covers the openings of the inner layer. If there is an overpressure in the packaging container resultant gas can escape into the open through the openings and the valve strip acts like an overpressure valve. As a result of the specialized disposition and embodiment of the valve strip and of the openings, a reliable escape of gas produced is achieved.
