1. The heat-sealing performance required for continuous molding of disposable paper cups and the printability of the PE film surface require factors such as ink components, residual solvents, and drying conditions to be compatible with the performance of paper cups.
2. The quality of paper cup printing is the result of the reasonable combination of printing machinery, printing process, substrate and ink. As long as one of them does not cooperate well, it will affect the printing quality of paper cup wholesale ink, or occur during the printing process. Fault.
3. Generally, flexographic water-based ink is used for paper cup paper printing. For water-based inks, the adhesion performance of the ink is critical. In order to avoid loss, it is generally necessary to do a lot of tests before official printing in order to choose ink with better adhesion.
4. Paper cup manufacturers can only obtain good light resistance, heat resistance, friction resistance and other properties of printed products only by choosing the appropriate ink. Therefore, in the printing process, the ink used for paper cup printing requires good adhesion, and the surface of the printed matter has good acid resistance, alkali resistance, water resistance, heat resistance, light resistance, and will not fade, discolor, or fade due to external factors such as acid and alkali. Ink layer peeling off and so on.
