Marine product packaging bag

Abstract

The invention discloses a marine product packing bag which comprises a bag body formed by stitching two pieces of plastic membranes, wherein an infiltration paper tapes are arranged on the side edges of the plastic membranes; bonding holes are formed on the infiltration paper tapes, and parts of plastic membranes inside the bonding holes are adhered to each other; water inside the inner chamber of the bag body can be discharged out of the bag body through the infiltration paper tapes; a sealing line is arranged at the bottom of the bag body; and water leakage holes are formed on the plastic membranes in a penetrating manner. The bag body with the water leakage holes can enable redundant water to be discharged quickly, and the water leakage holes can play ventilating and breathing effects during a long-term transportation process. One side of each infiltration paper tape is positioned inside the cavity of the bag body, and the other side of each infiltration paper tape is positioned outside the bag body. Therefore, water vapor and condensed water infiltrate on the side edges and are discharged out of the bag body slowly, so as to play an antibacterial effect. The parts of plastic membranes on the inner side of the bonding holes formed on the infiltration paper tapes are adhered to each other mutually, so as to form edge sealing structures on the two sides of the bag body. The marine product packing bag provided by the invention has the advantages of fastness in water drainage, maintenance of dry internally accommodated materials, good fresh-keeping effect, simple manufacturing technology, low cost and novel structure, and can inhibit the growth of bacteria.

Description

technical field [0001] The invention relates to a packaging container, in particular to a seafood packaging bag. Background technique [0002] The plastic film bag has the characteristics of low price, one-time use, convenience and sanitation. Therefore, in daily life, many liquid products are packaged in plastic liquid packaging bags. The plastic liquid packaging bag is usually a fully sealed structure. After the liquid product is poured into the plastic liquid packaging bag, the mouth of the bag is sealed. In order to ensure that the mouth of the plastic liquid packaging bag does not leak, the mouth of the bag is usually sealed with thermoplastic. When in use, the plastic liquid packaging bag needs to be cut open, and then the liquid in the bag is poured into other containers for convenient use. That is to say, the general use function of the existing plastic liquid packaging bag is limited to the packaging and transportation of liquid products. In actual use, it is nece...
