Basoplast 450 P is a new and highly cost-efficient polymeric surface-sizing agent (PSA) for the packaging sector. The product is suited for linerboard grades and complements the manufacturer’s range of anionic PSA in the graphical paper market. By replacing cationic PSA in packaging with Basoplast 450 P, paper manufacturers can now adjust the desired coloration on the surface with direct dyes, which can provide a more cost-efficient solution than incumbent systems, says the company. The new anionic PSA shows no foaming tendency nor sensitivity to pH or starch type, and can be used in both size or film press. — BASF SE, Ludwigshafen, Germany
