In the printing process of plastic woven bag cloth, some defects are prone to occur for various reasons, but why does this phenomenon occur?
Most of this printing problem is caused by the discoloration of the ink layer during the printing process, mainly because the corona treatment of the PPPE surface is not good, the temperature and relative humidity of the printing workshop are relatively large, and eventually lead to the dissolution of hydrogen bonds and weaving bags in the ink system The dissolved hydrogen bond of the printing is greatly reduced, and the woven package printing is very poor. The appearance of ordinary plastic woven bag is staggered in latitude and longitude, flat and not smooth. The appearance of the plastic woven bag is uneven, and the printed picture is uneven. For better printing, the flatness of the plastic woven bag should be done first, and then printed. This not only improves the flatness, but also provides a printing surface with good adaptability.
