To transport tuna, both corrugated containers and expanded polystyrene (EPS) containers are usually used. EPS containers, while having excellent thermal insulation, require a large storage space. Therefore, we provide “EPS Hybrid Tuna Container”which is a hybrid between EPS and cardboard. The EPS container is devided into two parts to reduce size when not in use, and fixed in a corrugated box when in use to create a durable thermal insulation container. The package saves storage space, enhances productivity compared to the conventional EPS containers and improves transport efficiency.
