The present invention discloses an easy-to-open packaging bag, comprising a bag body having a front sheet and a back sheet, wherein a height of the front sheet is smaller than the height of the back sheet, and an entrance of the packaging bag is arranged between an upper edge of the front sheet and an upper edge of the back sheet. A seal tab is arranged on the upper part of the back sheet and above the upper edge of the front sheet and comprises a release film layer and a pull tab from top to bottom in that sequence, wherein the release film layer is bonded with the seal tab via a first adhesive layer; the pull tab with an opening notch comprises a plastic layer bonded with the seal tab via a second adhesive layer, and a tensile strength of the plastic layer is greater than the tensile strength of the bag body. The object of easy opening is achieved by means of arranging a pull tab on the seal tab, with the pull tab being capable of being neatly pulled off.
