Sugarcane Bagasse Molded Fiber<\/h3>\n<p>Bagasse converts a milling byproduct into wet-press or dry-press trays. Key 2026 metrics: 0.8-1.2mm wall thickness, compressive stack loads of 80-150N, and compostability certified to EN 13432 \/ ASTM D6400 in home-compost timeframes (as low as 90 days).

PFAS-Free Aqueous Barrier Paperboard<\/h3>\n<p>The defining materials-science story of 2024-2026 was the phase-out of fluorochemical grease barriers. Modern <strong style='color:#0f172a;'>aqueous dispersion coatings<\/strong> (acrylic + bio-wax hybrid) achieve Kit ratings of 6-8 (400-600 g\/m\u00b2 grease resistance) at coat weights of 6-10 gsm while retaining full repulpability in standard mills.

PLA, PBS, and PHA Biopolymers<\/h3>\n<p>Injection-grade PLA (Ingeo-class) offers 60-65% CO2e reduction versus virgin PP but requires industrial composting access; PBS blends improve heat tolerance to ~100\u00b0C.
