The packaging industry is a fundamental pillar in ensuring that food products reach the consumer fresh and safe. In this context, Expanded Polystyrene (EPS) boxes, commonly known by the trade names “Foam” or “Styrofoam” (or “Polystyrene”), stand out as an ideal and vital solution in the food supply chain, especially for vegetables and fish. The function of these boxes is not limited to mere containment; it extends to include thermal preservation and mechanical protection, which ensures quality and reduces waste.
