Adhesive coating machine AVE-250E

They are designed to provide durability and different barrier properties and of course stable attractive colours. The trend to reduce the level of solvents in adhesives and paints has to also be taken into account. All this places high demands on the production process. AFS investments are a key part of this process providing adhesion to plastic, paper or metal surfaces as part of the packaging integrity so that the contents stay fresh. The required surface tension for printing, lamination and coating will reduce from the level reached by corona treatment during the extrusion process over a period of time in transportation or storage. This effect, caused by, for example, waxes and lubricants in the material requires that prior to the subsequent process Corona treatment is again necessary. By this so-called refreshment the surface tension of a substrate is increased, or the surface energy level reached in the first treatment is restored , so improving the wettability and the adhesion to the substrate surface. AFS offers a variety of system configurations, which can be based on the particular application, as standard or as a customised system easily integrated into existing and new production lines. End users as well as OEM customers benefit permanently from the great flexiblity, know-how and the innovations of AFS and enjoy technical perfection with simple operation..
