Aquatic product bag

An aquatic product packaging bag is a sealed bag with two openings, one for the loading port and the other for the water injection and oxygen filling port. Two openings may be provided at both ends of the sealed bag 1, one end having an loading port 2 and the other end having a water injection and oxygen filling port 3. The aquatic product packaging bag is provided with one end of the water injection and oxygen filling port 3, and a pouch 4 with water or oxygen backflow prevention is provided in the water injection and oxygen filling port 3. The outer surface of the pouch is bonded and sealed with the inner surface of the water filling and oxygen filling port 3 of the packaging bag 1 . The utility model does not need to use sand grains and vermiculite, thus avoiding the cleaning procedures of the aquatic products such as nereis, insects, stone insects and tube worms, saving time and trouble, increasing the survival rate of the aquatic products, and facilitating the transportation and delivery of the products. The cost can be reduced by 30%.
