Reduced carbon footprint with Kemira FennoBond

Production of lightweight packaging board promoted by environmental issues

Fiber based products account for the largest share of packaging materials globally, followed by plastics, metal and glass. The demand for packaging material is driven by the needs of the growing population, industrial growth, demographic and lifestyle trends as well as health and safety aspects. Growing awareness of environmental issues has also started to play a role in packaging business, which is seen in the regulatory requirements on reducing and recycling packaging material.

Paperboard producers are responding to these challenges by developing lighter and lighter products. Lighter packaging board provides lower environmental impact through reduced amount of packaging material needed, decreased transport costs, less waste and less raw material usage.

Lighter product with improved stiffness

The challenge in manufacturing lightweight packaging products is to maintain key properties like stiffness, strength and folding properties at lower basis weights. To address these challenges, Kemira has developed strength and stiffness enhancement chemistries that enable diverse benefits for the customer.

The strength additive Kemira FennoBond was used in a customer case to reach higher bending stiffness in folding boxboard. Kemira FennoBond was added to the top plies, which resulted in 10% improved bending stiffness and made it possible to produce lighter board. Altogether the strength additive brought the customer yield advantage and improved quality of the end product, as well as significant raw material savings and a reduced carbon footprint.
