Dispersion barrier coatings provide necessary functional properties for fiber-based packaging materials to protect the packaged goods from the environment and vice versa. Kemira’s FennoGuard™ dispersion barrier technology helps to reduce and replace plastic, e.g. PE extrusion, used in food packaging, and thus enables the development of fully recyclable paper or board packaging.
But reaching success with barrier technology requires more than just adding the right coating chemistry to the process. To use the new technology optimally and sustainably, paper and board manufacturers need to consider their whole process along the desired end-use properties.
Unique chemistry expertise and know-how of papermaking applications, from pulping to coating enables Kemira to support our customers in the creation of high-performing and cost-efficient dispersion barrier coated packaging material. Base paper properties, mill-level raw material circulation and stable waste water quality are essential to achieving an optimized dispersion barrier layer.
