摘要： A description is given of a paper valve bag with an inner panel which is located at the paper-bag end which is located opposite the paper-bag end with valve, and, on its surface which is directed toward the sack interior, the inner panel has an opening aid which has a higher modulus of elasticity than the inner panel. The opening aid, which may be a tear-open strip or a tear-open thread, projects beyond the inner panel at at least one surface-area end of the latter. Such paper valve bags are used for fine-grain, pulverulent and/or free-flowing materials, in particular ready-to-use mortar.
