Is the color of disposable paper cups very white? Don't think that the whiter the disposable paper cup, the better. The whiter and brighter the substance, the more likely it is to add a large amount of fluorescent agents, which can become potential harmful factors once they enter the human body.

Next, pinch the stiffness of the cup body. If the cup is soft and collapsing, it is likely that the cup will deform, leak, or in severe cases, the paper cup may not lift and affect its use. So consumers can imagine that some manufacturers can make disposable paper cups like this, and how much cost savings can be achieved compared to cups made by legitimate manufacturers. When consumers purchase disposable paper cups, they can roughly feel the stiffness of the cups by gently squeezing them on both sides with their hands.

If the consumer takes the cup and gently sniffs it with their nose. If you can smell a strong ink smell or a musty smell caused by improper storage of disposable paper cups and moisture, then the cups should be discarded and not used immediately. If the cup has a severe ink smell, it is definitely not food grade ink. If it is industrial ink, it contains benzene and toluene inside. Disposable paper cups are stacked together in varying sizes of 25-100 pieces during packaging. If industrial grade ink is used, the paper cups will definitely stick to the inner wall of the cup when stacked, which is not conducive to health. Mouldy disposable paper cups can produce mold, and mold entering the body through beverages will inevitably have an impact on consumers' bodies.
