Close the Loop’s polystyrene box alternatives are next-generation packaging solutions designed to replace single-use EPS foam in seafood, shellfish, and cold chain logistics. Developed for thermal performance, hygiene, and recyclability, these cartons and trays deliver the same protective strength as polystyrene, without the landfill impact. Crafted from food-grade corrugated or laminated fibreboard, each solution is flat-packable, lightweight, and compatible with air freight and export requirements. Whether you need Chilltainers for temperature retention or recyclable oyster trays for direct-to-market freshness, our designs combine sustainability, efficiency, and premium presentation for high-performance seafood logistics.
