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: 9649676Abstract: 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.Type: GrantFiled: October 8, 2013Date of Patent: May 16, 2017Assignee: CONSTANTIA TEICH GMBHInventors: Wilhelm Zuser, Adolf Schedl, Engelbert Scharner, Lambert Nekula, Martin Kornfeld, Rainer Huber, Christof Brunnthaller

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

Publication number: 20140322557Abstract: Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled to a thickness of less than 150 ?m in multiple cold rolling passes, and simultaneously a texture which runs in the rolling direction is produced on both faces of the foil. A loose composite formed from at least two of the aluminum foils, is fed into a pair of working rollers in a final cold rolling pass, wherein the relief-like surface structure which is produced in the rolling direction via a polishing process has been reduced by 10 to 50% with respect to the average roughness height in one region in a contrast- and motif-dependent manner on at least one roller surface in order to form a motif for a security feature. The security feature is transferred onto the aluminum foil face facing the roller surface, and the loose composite of aluminum foils is separated.Type: ApplicationFiled: August 27, 2012Publication date: October 30, 2014Inventors: Christof Brunnthaler, Rainer Huber, Martin Kornfeld, Adolf Schedl, Lambert Nekula, Wilhelm Zuser, Engelbert Scharner
