Metsä Board, Finland, reports that it has made major enhancements to its Avanta Prima, Simcote, and Carta Elega folding boxboards, following technical improvements made at its mills during the 2011-2012 investment program. The product enhancements improve the suitability of each cartonboard in the range for a particular packaging end-use such as food, beautycare, healthcare, or luxury packaging and graphics applications.
"We are responding to customer needs by making our boards even more fit-for-purpose," says Pasi Piiparinen, head of Metsä Board Paperboard. "Developments include better yield, optimized shades, and improved surfaces, according to the requirements of each end-use."
The bulk of Avanta Prima has been improved, meaning a lighter weight can be specified while maintaining the same thickness and stiffness. As a result, Metsä Board has further light-weighted grammages across the range. Avanta Prima has been developed to meet the requirements of the healthcare market, and its surface has now been optimized to allow for 2D data matrix coding. Its shade has also been optimized to enhance visual whiteness.
Simcote, with its effective combination of stiffness and consistency for food packaging, now has improved bulk for even better yield while maintaining the same thickness and stiffness. As a result, grammages have been light-weighted across the range, providing both cost and sustainability benefits.
The shade of Carta Elega has been optimized to enhance visual whiteness, an important characteristic in the beautycare market.
"We are happy to be able to offer our customers these changes, giving better performance in converting and printing, as well as an improved end result. They will also be able to utilize an even lighter weight board, achieving the same or even better performance in a finished carton," adds Piiparinen. "Using a lighter weight board also offers sustainability benefits, as less raw material is used, less weight is carried throughout the value chain, and less waste is generated."
