Claims (1)

[Scope of utility model registration request] A moisture-proof material such as a synthetic resin film or a synthetic resin tubular film is interposed as one layer of the bag base paper layer, and an adhesive is applied to one surface of the overlapping surfaces of the front and rear walls forming both bottoms, and a release agent is applied to the other surface. A moisture-proof material interposed as one layer of the bag base paper layer in a bag having a folded and square-bottomed bottom, an inlet formed in one corner of one of the bottoms, and an inlet covered with decorative paper on the upper bottom. A notch is formed in the air inlet and its vicinity,
Next, one end of the decorative paper having a hot-melt adhesive layer covering the upper base is pasted with an extra length so as to cover the air inlet, and the lower base has an opening with one end made into a double part. A heavy packaging bag made of decorative paper laminated with a peelable material.
