TopScreen is a range of ecological finished barrier coating formulations, used in the production of paper or board destined for packaging with specific barrier requirements. TopScreen barrier coating solutions can be adapted to meet additional specific customer requirements, like adjustments for machinability, glueability, coefficient of friction and tackiness.
TopScreen can be used both online and offline and is approved for a wide variety of paper and board packaging with food contact.
TopScreen are water based dispersions which contain a biopolymer based on vegetable oils, which meets direct food contact regulations. This coating technology is developed to replace hard to recycle wax emulsion or PE laminates in paper and board packaging. Paper and board coated with TopScreen are as easily repulpable as non-treated paper or board. By its very nature the biopolymer has no negative impact on the recyclability, repulpability or biodegradability of the packaging. TopScreen requires no stabilizers even with a high solid content, while viscosity remains low. Coating machines using TopScreen can simply be rinsed with water.
