Abstract: Composite materials, and sealing foils prepared with such composite materials for sealing a container, where the composite materials include an inner layer configured to face the container during sealing, the inner layer being single- or multi-layer, and including a self-contained and closed weakening line; an outer layer that may be single- or multi-layer, and that is configured to be peeled from the inner layer; where an area of the inner layer delimited by the closed weakening line remains attached to the outer layer when the outer layer is peeled from the inner layer, thereby creating a hole in the inner layer; the outermost of the inner layers is in contact with the outer layer, and includes a semicrystalline ethylene-propylene copolymer that is substantially free of dienes; and the innermost of the outer layers is a barrier layer or a lacquer.

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: For a simple, fast, safe and reliable determination of the layer thickness of a bonding layer between two layers of a packaging, a laser ultrasonic method is provided, in which the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is determined in advance, and a maximum (M1, M2, Mn) in the measurement signal (S) is sought, and the point in time of occurrence of this maximum (M1, M2, Mn) is determined as the total transit time (T1, T2, Tn) of the ultrasonic wave, and the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is subtracted from the total transit time (T1, T2, Tn), and the thickness (d) of the bonding layer is deduced from the known ultrasonic speed (vS) in the bonding layer (5).

Abstract: A bottle, especially a pharmaceutical bottle, configured to facilitate the withdrawal of goods present in the bottle in the form of pieces, the bottle being closed by a lid that consists of at least two layers: a cover layer and an outer layer. The cover layer, which may be a multilayer structure, is firmly sealed to the peripheral, circular sealing edge of the pharmaceutical bottle along said sealing edge, and includes a separation line off-set from the center of the circle. The outer layer, which may also be a multilayer structure, is connected to the cover layer across the entire surface thereof in such a way that one layer can be peeled off. The separation line of the cover layer has a concave section in the portion thereof that is next to the sealing edge, so as to form a flap section when the outer layer is peeled off.

Abstract: Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled down to a thickness of less than 150 ?m in a plurality of cold rolling passes, texturing that runs in the direction of rolling being induced simultaneously on both surface sides of the foil. In a final cold rolling pass, the foil is fed to a working roller pair, in which, on at least one roller surface, the relief-like surface structuring generated in the rolling direction by grinding was reduced on the basis of contrast and motif in a region of 10 to 50% relative to the average surface roughness to form a motif for a security feature that is transferred to the surface side of the foil facing the roller surface. The generated aluminum foil has a glossy appearance on both sides such that the security feature rises clearly due to its dull appearance.

Abstract: A lid for a pharmaceutical bottle that is configured to facilitate the withdrawal of goods present in the pharmaceutical bottle in the form of pieces, the lid including at least an inner layer and an outer layer. The inner layer, which may be a multilayer structure, is firmly sealed with and along the peripheral, circular edge of the pharmaceutical bottle and has a peripheral weakened line off-set from the center of the circle, where the peripheral weakened line of the opening has a concave section in the portion thereof that is next to the sealing edge. The outer layer, which may be a multilayer structure, is connected to the inner layer and can be peeled off such that the portion of the inner layer lying inside the peripheral weakened line remains on the outer layer, thereby forming an opening in the inner layer.

Abstract: A lid (2) for closing a cup (1) along a peripheral sealing edge (10) and a method for producing such a lid. The lid includes at least one aluminum film and an optionally multi-layered plastic layer which is co-extruded onto the aluminum film and has a closed predetermined tearing line (3). The plastic layer is made of plastic based on polyethylene (PE) or plastic based on polypropylene (PP), and the predetermined tearing line is introduced into the plastic layer preferably by means of a CO2 laser. The predetermined tearing line (3) may be provided directly in the region of the sealing edge (10).

Abstract: The invention relates to a method for producing a blank, which is composed at least substantially of material that can be embossed, in particular aluminum or an aluminum alloy, for closing a container along the edge thereof, in particular by means of adhesive bonding or sealing, the blank having an embossed surface and being stamped from a continuous material. The invention is characterized in that markings are embossed on the continuous material when the surface of the blank is embossed, said markings being used for the position determination during the stamping process.
