A method () for assessing quality of a transversal sealing () of a paperboard-based food package (), wherein the food package () comprises a longitudinal scaling (), and is provided with an reference imprint () in connection to the transversal sealing () is provided. The method () comprising, capturing (S), by a camera (), image data of the transversal scaling (), determining (S), in the image data, a position of the reference imprint (), determining (S), in the image data, a position of a reference line (), determining (S) quality measurement data of the transversal sealing () based on the position of the reference imprint () relative to the position of the reference line ().

Method for assessing quality of a transversal sealing of a food package

An anvil for forming a transversal sealing of a sleeve-shaped portion of packaging material holding a liquid product, said anvil comprising a main surface, in operation, facing the tube, and a ridge provided on the main surface, the ridge comprising a first section and a second section, wherein the first section of the ridge is placed below the second section such that, in operation, a stress in the packaging material formed by a hydrostatic pressure formed by the liquid product is shifted from a first part of the sleeve-shaped portion placed above the first section of the ridge to a second part placed above the second section.

Anvil, a transversal sealing system, filling machines, and a method for producing packages

An anvil for transversally sealing a tube having a longitudinal seam portion can include a first elongate contact surface and a second elongate contact surface. In some embodiments, the first elongate contact surface includes a first groove and the second elongate contact surface includes a second groove, each one of the first groove and the second groove being adapted to receive, in use, a respective section of the longitudinal seam portion of the tube. The first elongate contact surface can include a first seam interaction portion positioned within the first groove and having a first surface profile. The second elongate contact surface can include a second seam interaction portion positioned within the second groove and having a second surface profile. In some embodiments, the first surface profile differs from the second surface profile.
