The invention relates to the technical field of packaging materials, in particular to a woven bag and a weaving process thereof. The woven bag comprises a plurality of parallel across-warp ribbon-likefilaments and a plurality of warp ribbon-like filaments perpendicular to the across-warp ribbon-like filaments. The widths of the warp ribbon-like filaments are smaller than those of the across-warpribbon-like filaments. According to the woven bag, since the widths of the warp ribbon-like filaments are smaller than those of the across-warp ribbon-like filaments, the cover effect of the surface of the woven bag is good and the woven bag has the smooth surface; and a problem of folding of the across-warp ribbon-like filaments and the warp ribbon-like filaments during the weaving process is solved. Furthermore, the cover effect of the surface of the woven bag is improved and the current situation of the rough surface of the existing woven bag is improved.
