摘要： A method for producing a package which has a formed part with a product cavity, and a lidding film covering the product cavity. According to the method, a seam is defined, the seam is divided into sections, a pull-off force for pulling the lidding film from the formed part at least for a first section is determined, and the lidding film is sealed to the formed part. The sealing temperature for the first section is selected based on the pull-off force.

摘要： A method for producing and inspecting a package comprising at least one product cavity of a formed part sealed by a lidding film comprises the steps of: (a) sealing the lidding film to the formed part along a seam by means of a sealing device, which comprises a sealing contour with a plurality of segments; (b) detecting, by means of the sealing device, a parameter characteristic of the sealing quality of the seam in each segment; and (c) detecting a problem with the sealing according to step (a) based on the parameter detected according to step (b) in each segment.
