NOVELTY - The utility model claims a composite laver bag with outer layer fresh-keeping structure, the lower part of the sealing strip is provided with a sealing mechanism, packaging bag main body is provided with a nylon film layer from outside to inside, a high barrier layer, a printing layer, a polyethylene film layer, an anti-corrosion layer and an inner layer. The utility model claims a composite laver bag with outer layer fresh-keeping structure, the buckling strip and strip-shaped groove are butted and light according to the engagement; it is simple and effective sealing; the polyethylene film layer is set on the inner side of the food fresh-keeping packaging bag effectively protects the food in the packaging bag not used for the printing ink of the printed pattern on the printing layer and the pollution of the glue water used by the composite layer; safety is reliable; the anti-corrosion layer is made of graphene material; it has antibacterial action; therefore, the setting of the anti-corrosion layer makes the food not generate bacteria; at the same time, it also increases the food safety property; the inner layer is PTFE microporous film material; the material has high heat resistance, anti-corrosion antibacterial property; it can be directly contact with the food, which increases the safety of the food.
