Sappi has added a new corrugated board, Fusion Uncoated, to its range of container boards. This is a fully bleached fresh fibre liner based on the same paper concept as the existing Fusion Topliner.
However, where Fusion Topliner is double-coated, Fusion Uncoated has a natural, uncoated surface. It’s primarily aimed at those corrugated board and carton packaging applications that require a high white appearance for the topliner, inner liner and fluting, such as inserts for high-end perfume boxes as well as display and shelf-ready packaging, where uncoated paper finishes are often preferred. It’s also suitable for direct food contact.
Bernd Gelder, Sappi’s product group manager for Containerboard, says that the company’s core expertise is in producing fresh febre papers, explaining: “This makes the development of Fusion Uncoated a logical next step in our ambition to create an ever more appealing container board portfolio. We can now offer an uncoated surface with a natural look for the premium corrugated board sector. Fusion Uncoated is wood-free and impresses with its high whiteness and strength values.”
Fusion Uncoated is produced at the Sappi plant in Stockstadt. There’s a choice of seven weights available, from 70 to 130 g/m2,in sheet and roll formats, as well as a version approved for food applications, Fusion Uncoated OF, which is produced without optical brighteners. It’s suitable for use with offset, flexo, screen and digital printing.
