Barrier materials

Barrier materials are impermeable structures that prevent the inflow or outflow of gases, flavor and aromas and keep out impurities and potential contaminants. These can be used in many applications: they keep fuel vapors from escaping from the gas tank, they protect food from oxygen and impurities so it avoids oxidation and keeps its freshness for longer. Kuraray markets barrier materials for a wide range of processing technologies: co-extrusion, co-injection, lamination and coating using materials in the form of pellets, films and aqueous solution. With regard to sustainability, we develop new products to assist in optimization of the final product by increasing its shelf-life or reducing the amount of material required for a given purpose. In addition, our portfolio includes biodegradable and compostable products.
