When sewing, it is not allowed to take off the needle, break the thread, oblique seam, curling, etc., the seam is neat, and the remaining line of the upper seam cannot be in the center of the seam;  3. The layout logo of the composite bag should be clear and neat, bright in color, and the font should meet the standard of the sample bag, and the packaging bag should not have obvious oil or ink stains.  4. If the inner bag of the paper-plastic composite bag is a white transparent bag produced with new high-quality polyethylene raw materials, there should be no defects such as air bubbles, water marks, ruptures, holes, etc., and must have good tensile force and physical function, and meet the above requirements. Woven bags are the best quality woven bags.
