Flat lamination of panels and boards is commonly used in the construction and furniture industry. The surface-laminated panels are used in a wide range of areas, such as door, furniture components, floors, ceiling panels, but also as kitchen fronts, wall panelling among others.
Designers and architects are constantly working on innovative trends and products, which has led to an endless range of decors, colours and surface solutions. These often pose special challenges for the manufacturing companies. High gloss or super matt surfaces, for example, are very demanding to produce and require expert knowledge in terms of lamination and sheathing of panels and boards.
Know-how is the key to success
TAKA has many years of experience in the field of profile and flat lamination and employs a team of specialists who are available to advise our customers on all questions and projects. In this way we ensure that, thanks to its adhesives, our customers can manufacture high-quality and competitive products that meet the highest demands. Our specially founded Academy offers special training courses about flat lamination, aimed at machine operators as well as production managers.
The process of flat lamination
In flat lamination and panel wrapping, hot melt adhesives are usually used to bond the decorative films over the entire surface. This is usually done on industrial panel laminating machines, which apply the adhesive to the decorative material either by means of a slot nozzle or by roller application to the panel to be laminated. Depending on the production process, different working parameters must be observed to achieve the best possible results. In general, when there are above-average demands on the quality of the bond, PUR hotmelt adhesives are used, as they have the highest resistance to heat, moisture and chemical substances of all hotmelt adhesives.
Roller application in flat lamination is still the most widespread application method. The PUR adhesive is melted and then applied to the panel using a rotating application roller. The disadvantages of the roller application process are the imprecise adhesive application and the high cleaning costs of the system.
Slot nozzle application is still the most technically advanced solution for flat lamination. It is characterised by economical adhesive consumption and maximum precision in the adhesive pattern, which means that even demanding surfaces such as high-gloss and matt finishes can be produced in reliable processes. Similarly, slot nozzle application offers maximum flexibility in the application width of the adhesive and enables the panel edges to be wrapped (postforming) in the same process step.
Sustainability of TAKA PUR adhesives
TAKA optimises its in-house production processes with efficiency but also sustainability in mind. PUR adhesives for roll coater and slot nozzle are manufactured on the most modern production facilities, which are powered by electricity from 100% renewable energy sources. They work with closed water systems so that no fresh or drinking water must be fed in and rely on certified waste prevention and disposal solutions.
