Packing process is very important because it affects the quality of tuna during the journey. If the packaging is not good then the quality of the tuna will change when it reaches the export destination country. The export destinations of fresh tuna processing companies are Japan, the United States and the European Union. Things that need to be prepared for the packaging is a carton box size 120 x 50 x 40 cm, clear plastic, stereoform paper, and prickly ice. First the box is prepared and then given two plastics size 2 x 1.5 m and one paper steoroform size 1.5 x 1.5 m in it.
Then tuna inserted into the box. Tuna inserted usually amounted to 2-3 in one box. To prevent spoilage during the trip, the ice cultivator is inserted into the inside of the tuna head and around the tuna body. After that wrapped with plastic earlier. To prevent the sublimed ice, the plastic is tied with tape. Next box is closed and labeled. The contents of the label are the destination of delivery, the name of the sender, the name of the recipient, the weight of the tuna in the packaging, and grade . Then the box is tied with a plastic strap and taped at both ends to prevent air from entering. Lastly put in the car box and ready for export.
