ABSTRACT:
Pack.
Packs consisting of a multilayer composite sheet are frequently used for holding aroma-sensitive commodities, particularly ground roasted coffee. The pack is composed of a central (coffee) block (10) and of fin folds projecting at both ends. In the region of the fin folds a tear-open strip (17) is provided under a closure seam (11) to facilitate the opening of the pack.
The tear-open strip (17) likewise consists of a composite sheet and is connected to the pack-composite sheet by heat sealing to ensure that there is no impairment of taste of the pack's contents while at the same time guaranteeing a high-strength connection.
