Sustainable barrier coatings are an important and challenging growth area in packaging, with significant research at one end of the process and meaningful interest from consumers at the other driving substantial expansion.
Much of the focus is on coatings for paper products where a barrier coating is required to impede the saturation of the packaging material with grease or liquid.
In the broad range of the coatings market, for both plastic and paper-based substrates, biobased materials still make up a very small part, approximately 1.4% of the global total of sustainable barrier coatings in 2024 but are increasing at a rapid rate
