New packaging bag

In order to solve the problem of opening control, pouring pressure, and non-moisture resistance of powder and granular product plastic bag packaging, this patent maintains the existing package shape and adjusts the internal plastic line so that buffer particles can be poured out. The pressure is matched with a convenient sealable outlet so as to achieve easy opening, easy control of dosage and moisture protection. The cost and material of the present patented product and the current plastic bag are basically the same. The processing method is similar, but the performance is greatly improved. It meets the needs of the society for this type of product and has great market potential.
