For printing on the polyethylene bag based on the finished mockup printing plates (flexographic plates) are manufactured. Flexographic plate is a printing die manufactured of polymeric material that has well-defined hardness and thickness. Width and length of the flexographic plate depend on the size of the future image on the bag. The flexographic plate withstands rolling of one edition of 700000 – 800000 bags or 5 – 6 repeated bags. In such a way, in case of printing repeated editions you will not have to order flexographic plates again (of course, if you will not want to change the image on the bag).
