A container to hold aromatic substances which can be sealed aroma-tight with a composite film consisting of several laminae. The composite film on the top of the container is made up of an aroma-tight outer film having at least two laminae and an aroma-permeable inner film which is detachably bonded to the outer film by means of a bonding agent. The outer film can be applied onto the inner film or membrane film, which consists of at least two permanently bonded laminae, whereby the lamina adhering to the container is made of polyethylene and the third or top lamina is made of a polymer materialwhich has a different density. The surface structure of the side of the membrane film facing away from the container is selected in such away that the entire membrane film stays on the container when the outer film (16) is pulled off.

A container (13) to hold aromatic substances (14) which is sealed aroma-impermeable by means of a composite film (15) sealed to the container, the composite film (15) consisting of several laminae, whereby the composite film (15) on the top of the container is made up of an aroma-impermeable outer film (16) having at least two laminae (1, 3) including a barrier layer, and an aroma-permeable inner film (17) which is detachably bonded to the outer film (16) by means of a bonding agent (5) which forms an adhesive laminate, the outer film (16) being applied onto the inner film or membrane film (17), consisting of at least two permanently bonded laminae (6, 8), whereby the lamina (8) adhering to the container is made of polyethylene and the third or top lamina (6) is made of foamed polypropylene, the adhesive lamina (5) between the barrier layer or outer film (16) and the polypropylene lamina (6) adhering less strongly to the polypropylene (6) than does the adhesive lamina (7) between the polypropylene (6) and the polyethylene (8), whereby the specific density (kg/cm2) of the third or top lamina (6) is selected so that the membrane film (17) made up of the two laminae (6, 8) stays on the container (13) when the outer film (16) is pulled off.
