Bemis launches seam adhesive using DuPont’s biobased propanediol

In Massachusetts, thermoplastic films and adhesives company Bemis has launched a partially renewable seam adhesive for the garment industry. Dubbed Sewfree 3700, the adhesive is made using 25% biobased Susterra® propanediol produced by DuPont Tate & Lyle Bio Products. The adhesive is engineered to replace elastics and bulky sewn seams in garments. “It allows for sleeker lines, softer corners and stronger seams,” Bemis says. 

“This initiative is in direct response to our customers’ requests for more sustainable options in our core markets. We continue to improve not just our operational environmental performance as a manufacturer, but also deliver products that allow our customers to meet their impact objectives” says Alyssa Caddle, director of Sustainability and Corporate Responsibility at Bemis. “This product offers an opportunity to explore new ways to expand the portfolio of environmentally preferable adhesive options as we work towards our aspiration that all products demonstrate a measurable environmental benefit as compared to their predecessor by 2025.”
