The container is intended particularly for granular, pulverised or liq. prods. It consists of an exterior envelope (1) which is of composite construction comprising an exterior sheet of Kraft (RTM) paper (2) and two sheets of synthetic material (3, 5) separated by a sheet of aluminium (4), and an interior envelope (6) which can either be a single sheet of synthetic material or of composite construction with the synthetic material facing the inside of the container. The exterior and interior envelopes are joined only along the bottom (7) and lateral edges (8) of the container although the edges around the opening (9) may also be joined. |
