27-year-old Ms. Huang is a white-collar worker in a foreign company. She is a frequent visitor to fast food restaurants due to her busy schedule.

“cold” wax and “hot” film each perform its duties. In fact, the disposable paper cups usually used can be divided into cold drink cups and hot drink cups. Will threaten the health of consumers.
What is the biggest difference between these two kinds of cups? It lies in a layer of “wax” and a “film” in the production process. The production process of cold cup drinks is as follows: paper cup base paper direct printing, die cutting, forming processing .
In fast food restaurants, cold drink cups are mostly used to hold carbonated drinks and ice cubes, and there is a layer of food wax on the surface-because cold drinks will make the surface of the paper cup water, causing the paper cup to soften, and coating a layer of wax can waterproof .
When the temperature is between 0 degrees Celsius and 5 degrees Celsius, this wax is very stable and safe, but as long as the temperature of the water exceeds 62 degrees Celsius, the wax will melt, and the paper cup will deform by absorbing water. Different from the cold drink cup, a special film is attached to the surface of the hot drink cup, which not only has good heat resistance, but is also non-toxic and harmless under high temperature beverages.
Food wax: It may cause illness after melting. I will definitely ask some readers here. Since the food wax is sprayed on the cold drink cup, it shouldn’t be harmful to the body, right?
Food waxes are generally derived from natural plants and animals. The types of wax include beeswax, wood wax mixed, bee pollen, honey, beeswax thread, cream, red rice porridge, sugar water, etc. The efficacy and texture are similar to various wax products used in life. But because of the characteristics of its natural products. Wax is essentially different from other chemical products, so it is harmless to health when the intake of relevant ingredients is not exceeded.
Food waxes are produced from living organisms, and their main components are carbohydrates, fats, organic acids, etc., which can be used to polish and preserve food. After the food wax enters the human body, the above ingredients can be digested and absorbed by the human body.
Under normal circumstances, people will not consume a large amount of food wax at one time, so it will not cause harm to the human body. If you eat too much, it will cause excessive burden on the body’s material metabolism and decomposition organs, such as the liver and kidneys.
Food wax can lubricate the intestinal wall, prevent the absorption of water in the intestine, soften the stool and cause catharsis, and is used in medicine to treat constipation. Ordinary people eating food wax in large quantities can cause diarrhea. As mentioned above, Miss Huang’s diarrhea and other discomforts are not unrelated to the catharsis of food wax. Long-term consumption of this wax may also hinder the fat-soluble vitamins A, D, K and fat-soluble vitamins. The absorption of calcium and phosphorus can cause fat-soluble vitamin deficiencies, and even lead to degeneration of the bones, thighs, and myocardium. Old cattle are also prone to osteoporotic fractures and bone injuries.
For safety reasons, we recommend that you do not use cold drink cups to hold hot water for convenience. In addition to meltable dry hot water, food waxes are also easy to dissolve in grease. Therefore, do not use cold drink cups coated with food wax to hold oily food.
