At present, China does not have the concept of food-grade ink, and there is no printing ink that can be used for food contact. When the lips touch the mouth of the Cold Drinks Paper Cups when drinking water, the ink in the printed pattern may be ingested, especially the benzene-containing ink is more harmful to health.
At the same time, when the cup is set, there is a printed pattern on the bottom of the cup, and it is easy to rub the color on the inner wall of another cup, so the bottom also requires no printing.
When designing paper cups, we should try to avoid paper cup production design and use full-page printed paper cups. The full-page printed paper cups are piled up too heavily, and the paper cups are directly sealed and packaged. The organic compounds discharged from the solvent ink during the drying process, the isopropanol in the alcohol wetting liquid, and the volatilized gas of the varnish paint are harmful to human health.
In the sealed space, the background color of the full paper cup covers the whole cup body. When we use the paper cup to drink water, our lips will touch a certain position of the cup mouth, and it is easy to bring the above-mentioned chemical substances into the cup with the liquid. The body affects physical health.
Therefore, when designing and making paper cups, it is not advisable to design full-page printing, and the smaller the color block, the better. Similarly, it is not suitable to design graphics near the mouth of the cup, especially the block-shaped ink. Otherwise, it will have the same bad effect.
For the bar near the bottom of the cup, the text design should be raised by 5mm. Because after the cup slices are loaded on the machine, the bottom 5mm of the cup must be pressed to ensure the firmness of the bottom of the cup. However, the high temperature and pressure of the machine can easily distort the graphics and text near the bottom of the cup and affect the appearance. Therefore, when designing and making graphics, the text bar pattern near the bottom of the cup should be raised by about 5mm according to the height of the bottom of the cup.
