The sealing strips (3) comprise a first locking strip (31) and a second locking strip (32) that can be sealed to each other; the two long sides of the first locking strip (31) are sealed and fitted to one of the inner sides of the bag body (1); only the long side of the second locking strip (32) away from the bag mouth (2) is sealed and fitted to the other inner side of the bag body (1); on the bag surface provided with the first locking strip (31), a double-layer bag surface area (5) is provided on the side of the first locking strip (31) away from the bag mouth (2); the double-layer bag surface area (5) is provided with an opening (51) only on the side away from the first locking strip (31); the opening (51) is located on an outer layer (52) of the double-layer bag surface area (5); and the outer layer (52) is located on the outer side of the bag body (1). Skills are required to open the ziplock bag, thus effectively preventing children from opening the ziplock bag and contacting items in the ziplock bag, thereby avoiding danger.
