The Back Seam Laminated Bag is the same as other types of sewing bag. However, its main material is plastic woven cloth, and woven sack application is very wide, so the industry is used to call it "middle seam braided bag". The development of Laminated Woven Sacks is completely different from that of plastic bag and paper bag. The former is developed out of beauty, and back seam bag  is generally not easy to see. The latter is due to the limitation of its manufacturing process, because it is also a composite bag in terms of technology. Generally speaking, the plastic sewing bag has an obvious middle seam on the back of the bag.
