A live fish transport packaging bag and its manufacturing and using methods

Abstract

A transport packaging bag for live fish comprises a packaging bag body. An open part and a sealed part are arranged on the edge of the packaging bag body, a curve strip-shaped air inlet channel penetrating through the sealed part in the width direction is formed in the sealed part in a sandwiched mode, a first opening communicated with the external environment is formed in one end of the air inlet channel, a second opening communicated with an inner cavity of the packaging bag body is formed in the other end of the air inlet channel, and the width of the air inlet channel is gradually reduced from outside to inside. The transport packaging bag for live fish further comprises a one-way exhaust valve. The one-way exhaust valve is arranged on the side wall of the packaging bag body in a penetrating mode. The transport packaging bag for live fish is simple in structure, high in air storage capacity and not prone to breakage; besides, air in the bag can be replaced as needed, and the survival time of fish in the bag is long. The invention further provides manufacturing and using methods of the transport packaging bag for live fish. The manufacturing and using methods are easy and rapid to implement, low in cost and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of fish transportation packaging, and in particular relates to a live fish transportation packaging bag and its manufacturing and using methods. Background technique [0002] During the long-distance transportation, fresh and live seafood is very easy to die in large numbers due to lack of oxygen, pollution and other reasons, thus losing its original economic value. Especially for some live fish products with extremely fragile vitality, it is necessary to carry a large amount of oxygen transmission and power supply equipment during transportation to provide the conditions required for the survival of live fish products. These equipment and power supply are very heavy, occupy a large amount of transportation space, waste transportation costs, and the open oxygen supply is easy to pollute the living environment of live fish products, resulting in a large number of fish deaths.

AI Technical Summary

Problems solved by technology

But the opening of the transport oxygen bag is relatively large. When injecting oxygen and binding the mouth of the bag after injecting oxygen, air is easily mixed into the oxygen bag, reducing the amount of oxygen in the bag, thereby reducing the survival time of fish, and the oxygen bag The upper and lower layers of the bag are simply sealed by bonding, the peel strength of the bonding part is low, the bag structure is not stable during transportation, and it is easy to be damaged; in addition, the strapping straps set separately are easy to lose and inconvenient to use

[0004] Chinese patent document CN203392216U discloses a living body monomer fresh-keeping storage box, including a box cover with a vent hole and a double-layer structure box body, the outer layer of the box is a water storage layer, and the inner layer of the box is adsorbed with NaHCO 3 -Na 2 CO 3 The sponge layer of the buffer solution, the fresh-keeping storage box can absorb the CO released by the individual seafood in the box 2 , but when the fresh-keeping storage box is used, it needs to be filled with frozen tap water in the water storage layer in advance, which is cumbersome to operate and inconvenient to use; the individual seafood is in contact with the buffer solution, which brings certain food safety hazards

In addition, the storage box has a complicated structure and is relatively heavy, and the transportation and manufacturing costs are relatively high
