Starting from September 1, 2009, enterprises that have not obtained the production licenses for food paper packaging, containers, etc. listed in the first batch of catalogues may not produce disposable cups. However, taking into account the economic benefits, many printing companies have chosen to take the risk and quietly carry out disposable cup printing. So how can consumers identify the quality of disposable cup printing? Experts gave four suggestions.
A look: The lamp is blue, careful phosphor. Cups are in direct contact with the mouth and hygiene is especially important. Experts remind the public that when selecting disposable paper cup prints, do not just look at the color of the paper cup. Do not think that the more white the color is, the healthier it is. Some paper cup manufacturers add a lot of fluorescent whitening agents to make the cup look whiter. . Once these harmful substances enter the human body, they become potential carcinogenic factors.
Two pinch: cup body is not strong collapse, careful leakage. In addition, the use of cups with thick and stiff paper cups, cups with poor cup stiffness and pinching are very soft, and when poured into water or beverages, they can be severely deformed when they are lifted up, and they can even end up and affect their use. When choosing a disposable paper cup print, the public can use their hands to gently squeeze on both sides of the cup, which can roughly tell whether the stiffness of the cup body is good or bad.
Three smells: The color of the glass wall is fancy, beware of ink poisoning. Experts pointed out that paper cups are often stacked together. If it is damp or contaminated, mold must form. Therefore, damp paper cups must not be used. In addition, some paper cups will be printed with colorful patterns and words. When the paper cups are stacked together, the ink on the outside of the paper cup will inevitably affect the inner layer of the paper cups that are wrapped on the outside. The ink contains benzene and toluene, which is harmful to health. There are fewer paper cups with better print patterns.
Four uses: distinguish cold cups, hot cups. Experts pointed out that the disposable paper cups that we usually use can generally be divided into cold drinks cups and hot drink cups. They have their own roles. Once they are “misplaced”, they may threaten the health of consumers. The surface of the cold cup generally has a layer of food wax. The wax is very stable and safe at 0°C-5°C. However, as long as the water temperature exceeds 62°C, the wax melts, and the surface of the hot drink cup is affixed with a special film. Not only the heat resistance is good, but also non-toxic and harmless under the immersion of high-temperature beverages. The public must pay attention to distinction and do not use it indiscriminately.
