Publication number: 20240025152Abstract: A composite film for producing lids, including an aluminum layer and an extrusion layer, which is extruded onto the aluminum layer in multiple layers by coextrusion. The extrusion layer has a sealing layer and an adhesion promoter layer, which is arranged between the sealing layer and the aluminum layer. The sealing layer includes a polymer matrix, which has at least a first polymer constituent and a second polymer constituent. A peel-force additive, in particular a mineral filler, such as talcum, is added to the polymer matrix. The first polymer constituent is selected from a polyolefin, and the second polymer constituent is selected from polyolefin plastomers and/or polyolefin elastomers each having a density of less than 900 kg/m3, and from combinations of such materials.Type: ApplicationFiled: October 16, 2020Publication date: January 25, 2024Inventors: Alfred Wegenberger, Matthias Steiner, Roland Feichtinger, Patrick Relota

Patent number: 11718461Abstract: 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.Type: GrantFiled: July 7, 2020Date of Patent: August 8, 2023Assignee: CONSTANTIA TEICH GMBHInventors: Alfred Wegenberger, Martin Kornfeld, Adolf Schedl, Matthias Steiner

Patent number: 10401160Abstract: 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).Type: GrantFiled: March 12, 2014Date of Patent: September 3, 2019Assignees: CONSTANTIA TEICH GMBH, RESEARCH CENTER FOR NON DESTRUCTIVE TESTING GMBHInventors: Bernhard Reitinger, Saeid Zamiri, Clemens Gruensteidl, Juergen Roither, Martin Kornfeld, Alfred Wegenberger

Patent number: 8905251Abstract: 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).Type: GrantFiled: December 27, 2010Date of Patent: December 9, 2014Assignee: Constantia Teich GmbHInventors: Martin Kornfeld, Lambert Nekula, Alfred Wegenberger, Adolf Schedl, Franz Reiterer
