Board

Today’s consumers do a lot of shopping online which has driven changes in packaging materials. Product packages have to look appealing, be strong enough to survive being shipped around the world, and still look good when they are finally delivered. At the same time, consumers are expecting more sustainable packaging materials. Lighter weight packaging is one way to improve sustainability: lighter packages mean lighter load and reduced fuel consumption as well as reduced transportation costs.

Kemira chemistries enable reducing basis weights in board-making with no decrease in strength, stiffness or performance. We offer a portfolio of strength chemistries that enable the lightweighting of your sheet while increasing the strength and quality of your finished products. We can also improve your machine runnability and reduce sheet breaks and downtime. Overall profitability can be improved through fiber savings, lower energy consumption in the drying phase, less tonnage to transport, and reduced volume of the finished products.

Hygiene is the top priority for food service board suppliers. At the same time, paper machines are known to be prone to problems related to uncontrolled microbiological (MB) growth. The combination of potential troublesome MB growth and the need for a very high level of hygiene makes MB control a subject no paperboard producer can ignore.

Biofilm or slime growth on board machine surfaces can have drastic negative effects on both machine runnability and end-product quality. Uncontrolled bacterial growth causes unstable wet-end chemistry, taste or odor issues, spoilage of papermaking additives, and harmful bacterial sporulation. For example, a two-day outbreak of bacterial spores on a board machine can lead to the loss of thousands of tons of finished food packaging board, at a cost approaching millions of euros. With Kemira’s chemistry and application expertise, you can cure and protect your board machine from troubles caused by microbes.
