Our expertise in tuning barrier coatings will be an important asset in obtaining optimum performance for your specialty paper and board. We cover barrier properties like oleophobicity, hydrophobicity, flame retardancy and resistance to water vapor transmission.
Ecological Barrier Coating Solutions.
With the increasing regulatory pressures and growing customer demand for environmentally friendly packaging, the paper and paperboard industry faces many challenges. To be successful, the industry must find new ways of improving environmental performance.
Environmental challenges for barriers
Most barrier solutions available on the market are based on wax emulsions, polyethylene foils or additives containing harmful halogens (bromine, fluorine, etc.). Though these components give excellent results as a barrier, some require a complex and expensive production process. Even more importantly, these kinds of barrier components may have a very harmful impact on health and environment, or they result in packaging that is difficult and expensive to recycle or to repulp.
Therefore, all our barrier coating solutions are water-based and contain substances from renewable sources having no negative impact on recyclability and repulpability. They provide a price-competitive and environmental friendly alternative. Wherever necessary, our solutions are tested and certified so as to be compliant with authority regulations for both direct and indirect food contact.
