Engineered from the Substrate Up
At Cup Source, every product begins with material selection. Our R&D team evaluates pulp density, polymer crystallinity, barrier migration rates, and thermal conductivity to ensure each cup performs under real-world conditions.
We prioritize circularity without compromising barrier integrity or consumer safety. Our formulations meet strict food-contact regulations while offering verifiable end-of-life pathways.
📊 Material Lifecycle Tracking: All substrates are mapped from sourcing to degradation or recycling, with full EPD (Environmental Product Declaration) documentation available upon request.
Substrate Portfolio
Molded Fiber & Kraft Paper
Chlorine-free bleached pulp with optimized fiber length for structural rigidity and moisture resistance.
PLA / PBAT Blends
Plant-derived polymers engineered for clarity, flexibility, and industrial compostability. Optimized melt flow for thermoforming.
PET & rPET
High-clarity thermoplastic polyester. rPET grades meet FDA/EFSA direct food-contact standards with verified food-grade processing.
Water-Based & PLA Liners
Migration-safe barrier coatings that replace conventional PE. Engineered for leak resistance without compromising compostability.
