P&G and Lindner Announce Flexloop: A New Sustainable Solution Supporting Material Circularity

November 12, 2025

At this year’s K2025, P&G and Lindner proudly announced the launch of Flexloop, the latest innovative advancement in recycling. This new approach to recycling flexible films (e.g., outer packaging for bundled paper products or flexible plastic bags that replace rigid bottles) has been shown to achieve a higher quality recycled material compared to traditional recycling methods.

Flexloop addresses one of the biggest challenges in recycling: contamination present in plastic feedstock. Used plastics can contain impurities that migrate from the materials they have been in contact with, including odors, adhesives, and printing inks—which limits the use of the recycled material to downcycled applications like park benches or garbage bags.

P&G researchers sought to address the need for high-quality recycled plastic resin to be used in flexible film applications (outer packaging wrap/bags for bundled paper products and other goods, or flexible plastic bags which provide a lighter packaging solution versus rigid bottles). With expertise in polymer science and cleaning formulations, they adapted the proven polypropylene dissolution recycling process to address the challenge of removing surface inks and other migratable contaminants from flexible films (primarily LDPE and HDPE). With analytical expertise, they closely studied the material before and after the Flexloop process to confirm the removal of surface inks, labels, adhesives, and other unwanted substances. The process results in a high-quality resin suitable for reuse in a wide range of end-product applications.

With this announcement, Lindner and Procter & Gamble have introduced a pivotal innovation in mechanical recycling: a technology that is cost-efficient and scalable, while also fulfilling the increasing requirements of brand manufacturers for sensitive packaging in cosmetics, personal care and hygiene products. Plus, these advancements provide recycling companies access to a new product portfolio and additional sales markets.

According to Lee Ellen Drechsler, PhD, Senior Vice President of R&D, Flexloop was designed to meet the growing demand for high-quality recycled resin for flexible film applications. She noted that this partnership echoes P&G’s corporate commitment to scale up technologies that can help address significant environmental challenges, including creating ways for more used plastic to be fit for reuse rather than left as waste, helping to achieve a circular economy of materials.
