The technical solution of the utility model is: a kind of packaging bag, and this packaging bag is made up of inside and outside two-layer bag, and the bottom heat-sealing of inside and outside bag is affixed, at the end suitable for reading of inner bag convex-concave envelope line is arranged, and an outer bag end suitable for reading has the heat-sealing line.

The line of bag end heat-sealing suitable for reading outside side has tears mouth.

After adopting technique scheme, people can utilize the convex-concave envelope line on the inner bag repeatedly to open and seal, use that this packaging bag can unspent product carries out effective seal, deposits and effectively uses once more to breaking seal the back, thereby solved in the universaling packing and do not made the problem that unspent shelf life of products shortens greatly in the bag in packing unlatching back because of there being the effective seal measure, the later product of packing of being convenient to break seal is deposited and is used.Open packaging bag for the ease of the customer, the line of bag heat-sealing outside side has added one and has torn mouth.

Below in conjunction with drawings and Examples the utility model is described in further detail.
