The Poly Coated Paper Alliance (PCPA) has completed its 2026 Design for Mill Recyclability Guidance, the first comprehensive U.S. design guide for poly coated paper packaging, including milk and juice cartons, coffee cups, ice cream containers and other food and household packaging. The resource provides brands, converters, and manufacturers a common framework for designing poly coated paper packaging in closer alignment with U.S. paper mill end markets.
The release comes as Circular Action Alliance (CAA) finalizes its plan for implementation of extended producer responsibility in California. CAA can draw on the new guide as a mill-informed industry backed resource to inform fees and recovery strategies in California and in other states in which it is active.
While design guidance exists for other packaging formats and material types, poly coated paper packaging has lacked a comprehensive U.S.-specific resource. The new guide addresses that gap by identifying packaging features and components that can influence how these materials are reprocessed by paper mills.
The design guide is grounded in direct input from U.S. and Canadian mills representing more than 90 percent of consumption of the relevant recovered fiber grades that contain poly coated paper packaging, including Grade 54 Mixed Paper, Grade 52 Cartons, and other poly coated white fiber grades.
“This guide brings the operating realities of paper mills directly into the packaging design process,” said Jason Pelz, vice president of recycling for the Carton Council. “By grounding this work in direct mill feedback, we’re helping the industry better understand where compatibility exists today and where more work is needed.”
The guidance uses four compatibility categories – fully compatible, conditionally compatible, not compatible, and unknown. The framework was informed by existing global guidance, including the 4evergreen Alliance, and adapted for U.S. mill conditions based on mill feedback. Additional testing, including RFID tracking, optical sorting, and bale audits conducted by the PCPA, helped inform the guidance.
The findings show that seemingly small design choices can influence how poly coated paper packaging performs at end markets. Mill feedback identified differences in compatibility across coatings, adhesives, and other non-fiber components. This includes the latest guidance for repulpability standards.
“Industry-developed guidance like this fills a real gap,” said Scott Byrne, vice president, global sustainability & industry affairs for Sonoco. “Having a credible framework already in place gives producers a resource we can consider as EPR implementation moves forward in California and across the country.”
A summary of the 2026 Design for Mill Recyclability Guidance is available on the Poly Coated Paper Alliance website. The full design guide is currently only available to PCPA members, advisors, and partners. PCPA plans to make the complete design guide publicly accessible after further industry engagement in the coming year.
The resource is not a mandatory standard or guarantee of regulatory compliance. PCPA will continue to update the resource as new mill input, testing, standards and regulatory requirements emerge. Brands, converters, mills and other stakeholders interested in the 2026 design guide, or in helping to shape future versions, are encouraged to get involved with PCPA.
