Let's first break down the inferior paper cup, which consists of paper, printing ink, industrial paraffin, and coated paper. Below are explanations in sequence.
1、 Paper: Many manufacturers do not use food grade wood pulp paper in order to maximize profits. There are plenty of inferior products passing off as good. If the paper quality is poor (recycled waste paper), bleach and fluorescent whitening agents are used, which ordinary consumers cannot distinguish.
2、 Printing ink: In an era where production costs determine everything, the national standards for printing ink seem to be ineffective. Therefore, inks containing benzene and toluene are also flooding the market. After the printed paper cups are stacked, the ink is likely to contaminate the inner wall of the paper cups.
3、 Industrial paraffin: Can paper cups still hold water without waterproof treatment? Therefore, there is a type of paper cup that has been soaked in paraffin wax. Wax contains a harmful substance called polycyclic aromatic hydrocarbons, and the melting point of wax is 40 ° C, and oil can dissolve wax. You understand the consequences.
4、 Film coated paper: This is what most people call it, but it is actually an inner polyethylene plastic film. Many paper cups use coated paper instead of paraffin wax. But without the "protection" of paraffin, the outer wall of the cup may become moldy when exposed to moisture, and when stacked, the inner wall of the cup will be contaminated by mold. As for this plastic film, if it is not a food grade material, it will decompose into harmful substances at high temperatures.
In addition, inferior paper cups have been found to contain bisphenol A. According to experts from Nanjing Medical University, the content of bisphenol A in some daily necessities was measured, and the results showed that the bisphenol A content in disposable paper cups used in experiments was 30 times that of disposable plastic cups, and the bisphenol A content in rainwater was more than 5 times that of purified water in water dispensers.
