PIP understands the importance of reducing waste to lower costs and minimize environmental impact. Our new, sustainable ECOSeries BioSoft ear plugs are the first to be made from bio-based technologies. The BioSoft ear plug foam material provides the same fit and performance as conventional polyurethane or PVC materials, but with a lower carbon footprint. This innovative technology not only reduces emissions during manufacturing, but it contains bio-based materials making BioSoft more environmentally friendly at end of use.
