Abstract

The invention belongs to the technical field of packaging bags, and especially relates to a food packaging bag. The food packaging bag comprises a packaging bag body, wherein an air leakage mechanism is arranged on the packaging bag body and comprises a cylinder, the cylinder penetrates through the packaging bag body and is fixedly connected with the packaging bag body, and two first annular blocks are fixedly arranged on the cylinder in a sleeved mode; the two first annular blocks are located inside and outside the packaging bag body separately, the sides, close to each other, of the two first annular blocks are fixedly connected with the packaging bag body, a sliding block is slidably installed in the cylinder, a second annular block is fixedly installed in the cylinder, and a push-pull rod is fixedly installed at the side, away from the second annular block, of the sliding block; and the end, away from the sliding block, of the push-pull rod extends out of the cylinder and is fixedly provided with a shifting block. According to the invention, the interior of the packaging bag body can be vacuumized, the vacuum sealing performance in the packaging bag body is ensured, and therefore the storage time of dried fruits in the packaging bag body can be prolonged.

Description

Technical field [0001] The present invention relates to the field of packaging bags, in particular to a food packaging bag. Background technique [0002] At present, the dried fruit packaging bag After opening, even if the air in the package is very good, the air entering the bag cannot be completely discharged, so it is easy to make the dried fruit in the package bag when opening the bag is temporarily stored, so the dried fruit The quality changes, and when eating outdoors, due to the deposit of dried fruit peels, it is not conducive to environmental protection.
