The vividness of color water-based ink printing food packaging bags
When it comes to the printing of food packaging bags, the first thing that comes to mind is definitely “safety”, if the bags used to package food and medicine can not guarantee the safety, but will be safe food contamination, which is unacceptable to us.
Food packaging safety is more and more often mentioned. In the past, people will pay more attention to the food, and not to pay attention to the packaging. But with the increasing awareness of safety and the pursuit of packaging, the safety of food packaging is more and more concerned as food.
Water-based ink has a very high safety level. It can be used in food and toy packaging.As for the water-based ink color vividness and gloss, the reason for this result is because of the natural gap in the characteristics of water-based ink, early due to the limitations of materials and technology, the proportion of pigments in water-based ink can not be too high, otherwise it will be hard to the performance of the ink, and now the proportion of pigments in water-based ink can already reach 25% with UV ink, so in the face of almost and UV ink The difference is almost no difference, with the naked eye can hardly see the gap.
Water-based ink is not only in the printing cost is much lower than UV ink, in the safety is also guaranteed, printing efficiency, now the new flexographic printing machine to reach 500 meters per minute printing speed is also no pressure, so we can foresee the future of water-based ink will be in more areas of great splendor.
