PCT No. PCT/SE96/00964 Sec. 371 Date Dec. 5, 1997 Sec. 102(e) Date Dec. 5, 1997 PCT Filed Jul. 19, 1996 PCT Pub. No. WO97/07025 PCT Pub. Date Feb. 27, 1997A method of carrying out quality control of a packaging container or packaging container blank comprises providing a package or blank having one or more poles (12) for interconnection with electric quality control equipment (24). The packaged product (20) will be directly or indirectly electrically accessible, whereby both the quality of the packed product and the tightness of the surrounding packaging container (1) may be determined in a rational and partly automated manner. This is of particular importance in the production of aseptic packaging containers for, for instance, ready-made, heat-treated soups or similar foods.
