  • the method is described with the aid of figures 10a, 10b and 10c . In these pictures a bulging package is shown to make it easier to describe the method. To better show the test method a stiffening element that is not stiff enough has been chosen so that the package bulges more than a package according to invention should have done.
  • a package 1 with a stiffening element 10 is laid flat on a table with the front side panel 4 of the outer cover lying down on the table top 14. Find the part of the end side panel 3 of the outer cover that bulges the most, this part can usually be found at half of height H s of the end side panel. Push a vertical ruler 15 until it comes in contact with an end side panel 3 of the outer cover 2 where the package bulges most. If the end side panel 3 of the outer cover 2 has a seam that is protruding push gently until the seam lies flat against the outer cover and the ruler 15 is flush against the part of the material that is adjacent of the seam, alternatively a part of the seam that coincides with the measurement site can be cut or shaved away without destroying the seam. With a finger find the back edge 17 of the stiffening element. With the help of e.g. a horizontal ruler 16 measure the distance D from the back edge of the stiffening panel and the vertical ruler 17. The angles ⁇ and ⁇ shall be 90°.
