Preferably, the outer surface of the expanding body is provided with the first waterproof layer.
Preferably, all or part of avris of the expanding body is provided with the anti-water seal obtained using immersion or coating
Side.
Preferably, the first waterproof layer that the waterproof edge sealing includes the paper layer of expanding body and is located in paper layer
With the second waterproof layer.
Preferably, the inner surface of the paper layer and outer surface are equipped with the first waterproof layer.
Preferably, on the inside of the sealing tongue or external side of bag is provided with glue line with sealing tongue corresponding position.
Preferably, waterproof edge sealing of the glue line along sealing tongue is set, or is prevented along on sealing tongue
Water seal side correspondence position on bag body is set.
Preferably, when being set along the waterproof edge sealing of sealing tongue, glue line both ends are extended in sack.
Preferably, the bag body is provided with two-dimension identification code.
Preferably, the inner surface of the expanding body is provided with composite membrane.
Preferably, the waterproof edge sealing is that waterproof soaks process layer or coat.
Preferably, the width of the waterproof edge sealing is 1mm-20mm.
Preferably, glue line is provided with anti-sticking diaphragm.
Preferably, when the glue line is arranged on sealing tongue, the side parts of glue line and anti-water seal
Side is overlapping.
Preferably, the glue line along sealing tongue avris set when, both ends extend in sack 1mm with
On.
Preferably, the expanding body inner surface is provided with composite membrane.
Compared with prior art, beneficial effect is the utility model：Not only the entirety of sack has carried out waterproof measure, in bag
The side of the bonding part of son is also provided with waterproof edge sealing, can avoid water in the bonding part of sack by expanding body by waterproof edge sealing
Section enter expanding body inside, the expanding body of papery is drenched, so damage sack structure.Water is avoided to enter further into
