Abstract: Capsule for taking up, in particular, powder or granular substances, having a base body (22) which is suitable for taking up a powder or granular substance and which has an opening (26), and having a cover for closing the opening (26) of the base body (22), the cover being a covering foil having an aluminium-containing carrier and a coating (4) arranged on this carrier (2), the coating being an atactic coating containing polypropylene. Furthermore, the invention relates to a foil (1), in particular a covering foil for closing an opening of a base body (22) suitable for taking up a powder or granular substance, forming a capsule, the foil comprising an aluminium-containing carrier and an atactic, polypropylene-containing coating arranged on this carrier (2), as well as a method for manufacture of such a foil (1), a carrier made of an aluminium-containing material being provided and an atactic, polypropylene-containing coating (4) being arranged on this carrier.

Abstract: In order to be able to set the bending stiffness of a composite material having at least two plies connected by a laminating agent, it is provided that a mixture of a first, curing adhesive and a second, non-curing adhesive is used as laminating agent, wherein the bending stiffness of the composite material is set by the mixing ratio of the two adhesives.

Abstract: A packaging laminate including a support layer made of aluminum and a polyolefin layer bonded thereto via an adhesive layer or adhesion promoter layer and having high bond strength. It is provided that the surface of the support layer facing the adhesive layer or adhesion promoter layer includes a modified surface layer produced by silicatization or titanization.

Abstract: A lid for closing containers includes an at least two-layered composite assembly. A layer facing the container seals against a container edge and forms an opening by layer separation, for removing contents. The layers have a continuous construction without weakening lines. The layer facing the container is made mainly of a plastic having an intrinsic tearing resistance being lower in the region of the opening than its adhesion to the layer facing away from the container in a remaining region and an adhesion to the container edge being greater at least in the region of an opening aid than to the other layer. The plastic adheres so strongly to the outer layer in the region of the opening that a region corresponding to the opening is torn out upon opening and a remaining layer of the lid facing the container continues to adhere to the container edge by sealing action.
