Patent number: 11884023Abstract: An apparatus for quality assessment of a sealing section of a package for food products. The package comprises at least a robustness layer and a plastic layer. The sealing section is formed by holding a first section and a second section of the package against each other while providing heat such that the plastic layer of the first and second section melt and thereby provide for that the first and second section adhere to each other. The apparatus comprises a sample holder arranged for fixating a sample comprising the sealing section of the package, wherein at least part of the sample holder is transparent, a magnification device arranged on a first side of the sample holder, and an illumination device arranged on a second side of the sample holder, such that light is provided to the magnification device through the sample holder, wherein the first and second side are opposite sides of the sample holder.Type: GrantFiled: December 24, 2022Date of Patent: January 30, 2024Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Hans Hallstadius, Magnus Råbe

Publication number: 20230356872Abstract: A method for transversally sealing a packaging material tube, comprises placing a transversal sealing section of the tube between a sonotrode and an anvil. The transversal sealing section comprises a first two-layer sub-section, a three-layer sub-section and a second two-layer sub-section, transmitting ultrasonic acoustic vibrations, having a frequency and an amplitude, from the sonotrode into the transversal sealing section, thereby melting the plastic foil in the transversal sealing section, and pressing the tube together between the sonotrode and the anvil to bond the plastic foil such that transversal sealing is formed. The anvil has a ridge comprising various sub-sections for receiving various ones of the sub-sections of the tube, wherein the ridge has equal height in at least some of the sub-sections. The frequency, amplitude, pressure and paperboard properties are chosen to achieve equal temperature in the first two-layer sub-section, the three-layer sub-section and the second two-layer sub-section.Type: ApplicationFiled: September 29, 2021Publication date: November 9, 2023Applicant: TETRA LAVAL HOLDINGS & FINANCE S.A.Inventors: Magnus RÅBE, Magnus LINDVALL
