Definitions

  • a protective layer is applied to stackable articles.
  • the hot melt adhesive is applied directly to the predetermined areas of the surface after the production of the objects.
  • the adhesive quickly becomes hard, and then another substrate can be directly stacked on the thus coated substrate. Due to the adhesion on the surfaces, the protective elements do not slip during transport. Due to the low adhesion, the objects can be easily separated from each other. Then the protective element should be well removed from the other substrate. It can be seen that the hot melt adhesive dissolves completely from the substrate surface. There are no residues or impurities. The good application at low viscosity and the rapid solidification of a fast stacking and packaging of the objects is possible.
  • Strips 20 x 200 mm are cut out and the adhesive force (90 °, 10 mm / min) is measured.
