A tear strip can be detachably connected on the top surface of the main piece. The side of the tear strip is connected to the side of the easy-tear piece. A protective strip is fixed on the side of the main piece facing the secondary piece. The side of the protective strip is fixed and connected to the bottom surface of the tear strip. The tear strip is composed of two slices of another piece. The side of the tear strip is fixed to another piece. The thickness of the easy-tear piece is half the thickness of the main piece. The end of the tear strip needs to be heat-sealed and reinforced to better fix it on the bag body.
