Bostik, the adhesive solutions division of Arkema, has announced the launch of Nuplaviva™, a series of new products formulated to meet disposable hygiene article manufacturers’ needs for adhesives with renewable content. As sustainability becomes a greater area of focus throughout the disposable hygiene industry, bringing these adhesives to market allows Bostik to further support the corporate social responsibility (CSR) efforts of producers for baby care, feminine hygiene, and adult incontinence products. Nuplaviva adhesives, initially two products with 50% and 75% bio-sourced content, respectively, reportedly provide the same performance and ease of processability as Bostik’s traditional adhesive formulations.

“During the research and development stages of Nuplaviva™, it was important we designed an end-product that, although bio-based, article manufacturers did not need to make any changes to their equipment or processes to use,” said Christophe Morel-Fourrier, Bostik’s global marketing manager for Market Insights and Sustainable Innovation. “Exacting the formulas to meet the demands of high line speeds added another layer of complexity. But our researchers were successful in meeting expectations for behaviour and performance with both Nuplaviva™ 50 and Nuplaviva™ 75.’’

Bostik reports that compatibility with respect to substrate usage in various diaper, pad, and pull-on pant designs was top of mind for its scientists as they explored and experimented with the Nuplaviva formulations. Not only do these adhesives work well with traditional substrates, but testing has also proven they complement the use of a variety of more sustainable substrates. This allows article producers to further advance their sustainable development objectives.

“Adding bio-sourced content to our adhesives reduces our dependency—and ultimately our customers’ dependency—on the use of fossil carbon,” Morel-Fourrier said. “Resource conservation is at the heart of our circular model. Bostik as a whole is making efforts to modify its own manufacturing process, so it is more efficient, less energy intensive, and generates less waste.”
