The coating, now under patent, is the result of a collaboration between materials scientist SonBinh Nguyen and mechanical engineer Timothy Wei. Through GO-Eco, a Northwestern-affiliated startup, the technology has transitioned from lab development into industry testing. Wei, who also serves as chief scientist at Chang Robotics, emphasized the goal was to move beyond theory and into viable manufacturing solutions.
Tests conducted at Western Michigan University’s Paper Pilot Plant reported performance improvements ranging from 30 to 50 percent in barrier resistance and substrate strength when compared to current commercial coatings. These results were achieved with only small additions of graphene oxide, helping maintain price parity—critical for large-scale adoption across sectors like quick service restaurants, consumer packaging, and grocery retail.
Unlike PFAS-based coatings, the graphene oxide formula can be applied to a variety of materials—such as molded fiber products, cardboard boxes, and disposable paperware—without affecting recyclability or compostability. This gives it a notable edge as businesses face increasing demand to meet sustainability targets without sacrificing product quality.
The single-atom-thick structure of graphene oxide delivers practical advantages: it’s non-toxic, lightweight, and adaptable to existing production workflows. Field tests have confirmed the coating’s applicability across packaging types, from cups and straws to clamshell containers and produce bags. For businesses focused on customer experience, the additional strength and leak-resistance also help reduce complaints over soggy or flimsy packaging.
GO-Eco has secured early-stage investment from a national tableware manufacturer and is actively collaborating with partners to finalize product development. Regulatory approvals for food contact safety are in process, alongside certifications for compostability and recyclability—two key considerations for packaging buyers navigating evolving compliance requirements.
