  • tubular bag packaging is used with advantage wherever it is necessary to pack liquid to pasty substances in small quantities.
  • the removal is typically carried out after a targeted destruction of the outer skin of the tubular bag packaging.
  • the mixing of the separately packaged components typically occurs either by combining the components outside the package, for example by blending with a spatula, or by blending the components within the package, for example by opening a closure in the package and then kneading the now interconnected components.
  • the multicomponent composition has to be processed quickly, for example because of a short pot life or high time pressure, a homogeneous mixture of the components must be achieved quickly.
  • FIG. 1 shows a package for separate storage and subsequent mixing of several components, comprising a container 1, which is formed from a first wall 2 and an opposite second wall 3.
