Sonoco Expands Sustainable Packaging with EnviroFlex® Paper Pre-qualification for How2Recycle® Labeling

HARTSIVLLE, S.C., April 03, 2023 (GLOBE NEWSWIRE) -- Sonoco (NYSE: SON) announces that the high barrier paper-based structure, EnviroFlex® Paper Ultimate (ULT) 1.0, has received How2Recycle® pre-qualification and has met all requirements of the Fibre Box Association’s Voluntary Standard for Repulping and Recycling. This pre-qualification comes as a result of Sonoco’s ongoing efforts to develop innovative, sustainable packaging solutions.

EnviroFlex Paper ULT 1.0 is a superior oxygen, moisture, and grease barrier packaging solution available in various formats, including rollstock, heat/cold seal, sachets, and pre-made pouches. EnviroFlex Paper ULT 1.0 provides exceptional protection and preservation for perishable items, such as baked goods, confections, pet treats, salty snacks and powdered beverages, while being curbside recyclable. Sonoco understands the importance of providing safe and non-toxic materials in convenient formats. Therefore, the company has gone above and beyond to develop EnviroFlex Paper ULT 1.0 and a host of other paper-based structures without the use of chemicals of concern, such as PFAS and PVDC.

“At the heart of our success is our talented R&D team and cross-supply chain collaboration, which has enabled us to develop and bring a portfolio of paper solutions to market that is both sustainable and effective,” said Sonoco Global Environmental, Sustainability, and Technical Services Vice President Elizabeth Rhue. “Through our advanced technology scouting program and development of internal testing, our team has worked tirelessly to create products that meet the demands of today's environmentally conscious consumers without sacrificing quality or functionality.”

How2Recycle is the first standardized label system that allows companies to accurately track and measure the recyclability of packaging. The on-pack labeling was created to provide consistent and transparent recycling information for US and Canada consumers.

EnviroFlex Paper can make a real difference in reducing waste and promoting responsible packaging practices. With the How2Recycle pre-qualification, this product will continue expanding Sonoco’s reach and provide access to circular and innovative packaging solutions.
