Regulatory pressure (EU PPWR, EPR fees in 12+ U.S. states) plus fiber costs have ended the era of over-specified board. This guide gives engineers and procurement leads the verified specs, compliance thresholds, and unit economics required to specify sustainable packaging without structural failure risk.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>The 2026 Regulatory Baseline<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">The EU Packaging and Packaging Waste Regulation (PPWR), fully applicable since January 2025, drives global material decisions in 2026:<\/p>\n<ul style=\"margin:16px 0; padding-left:24px; line-height:1.75; color:#334155;\">\n<li style=\"margin-bottom:8px;\"><strong style='color:#0f172a;'>Recyclability grading:<\/strong> All packaging must be graded A (\u226595% recyclable by weight), B, or C by 2030.
