How to distinguish the quality of disposable paper cup printing?

1. When choosing disposable paper cups, it's not just about whether they can dry clean or not. Some paper cups look very white and comfortable, and many people think that these cups are the best, but in fact, the opposite is true. Some paper cup manufacturers add a large amount of fluorescent whitening agents to make the cups look whiter. Once these harmful substances enter the human body, they can become potential carcinogenic factors. Therefore, experts suggest that when choosing paper cups, it is best to place them under a light. If the paper cup appears blue under fluorescent light, it can prove that the fluorescent agent in the paper cup exceeds the standard. Therefore, consumers should be cautious when using it. As a printing factory, both the use of ink and the selection of paper consumables must pay attention to safety.

2. If the disposable paper cup becomes soft and not firm after printing, be careful of water leakage. In addition, it depends on the hardness of the paper cup. Some quilts have poor stiffness, and when poured with water or drinks, they will deform severely when held, which seriously affects their use. Experts point out that generally high-quality paper cups can hold water for 72 hours without leaking, while poor quality ones will leak water in half an hour.

3. Paper cups are usually stacked together, and if the environment is humid, it will inevitably cause mold. Therefore, it is best not to use paper cups that have been damp in daily life. In addition, when paper cups are stacked together, the ink on the outside of the cups affects the inner layer of the wrapped cups. At this time, attention must be paid because the ink contains benzene and toluene, which are harmful to health. So when purchasing disposable printed paper cups, it is best to choose paper cups with no ink printing on the outer layer or with less printing.

4. Before printing disposable paper cups, strict distinction should be made between cold and hot cups, each with its own function. Experts point out that the disposable paper cups we use in our daily lives can generally be divided into two types: cold drink cups and hot drink cups, each with its own functions. Once they are "misplaced", they may pose a threat to consumers' health.
