PTThe film has good operability and ink adhesion, no static electricity, and is not easy to absorb dust.PTIt has good hygroscopicity, and the elongation becomes larger after absorbing temperature, resulting in wrinkles or slack, which affects the quality of printed graphics. In addition, the ink adhesion will decrease, so it is necessary to pay great attention to the ambient temperature of storage and printing. Its tear resistance is poor. If there is a crack on the edge, it is very easy to tear along the crack. It is necessary to prevent the edge from splitting during cutting and printing. . It shrinks, loses strength or becomes brittle as it dries. Therefore, the drying temperature should not be too high. In addition, pay attention to tension control to prevent stretch deformation and wrinkles.
