We use disposable paper cups in many places, but do you know that buying disposable inferior paper cups causes a lot of harm? Specifically, we first decompose the inferior paper cup, its composition is: paper, printing ink, industrial paraffin, film paper. The following disposable environmental protection tableware manufacturers to the machine in turn to explain.

一、紙:許多廠家為了利益擴大化，并不會用食品級的木漿紙。以次充好的比比皆是。如果紙質不佳(回收利用的廢紙)便用漂白粉和熒光增白劑，這是普通消費者無法分辨的。

Paper: Many manufacturers do not use food grade wood pulp and paper for the sake of profit expansion. Subprime is everywhere. If the paper quality is not good (recycled waste paper), then use bleaching powder and fluorescent brightener, which is indistinguishable from ordinary consumers.

二、印刷油墨:在生產成本決定一切的年代，關于印刷油墨的標準似乎不見效。因此含有苯和甲苯的油墨也充斥在市場里。對于印刷過的紙杯套疊以后，油墨就很可能污染紙杯內壁。

2. Printing ink: In an era when production costs determine everything, national standards for printing ink seem to be ineffective. Therefore, the ink containing benzene and toluene is also flooded in the market. For printed cups, after overlapping, the ink is likely to contaminate the inner wall of the cup.

三、工業石蠟:紙杯如果不做防水處理，那還能裝水嗎?因此有一種紙杯是石蠟泡過的。蠟含有一種叫"多環芳烴"的有害物質，而蠟的熔點是40°，且油可以溶解蠟，后果你懂的。

3. Industrial paraffin: Can paper cups hold water if they are not waterproof? So there is a kind of paper cup that has been soaked with paraffin. Wax contains a harmful substance called polycyclic aromatic hydrocarbons. The melting point of wax is 40 degrees and oil can dissolve wax. You know the consequences.

四、淋膜紙:一般大家都是這么叫的，但其實是內聚乙烯塑料膜。很多紙杯用淋膜紙代替了石蠟。但是沒有了石蠟的"保護"杯子外壁在受潮后可能會發霉，套疊起來的杯子，內壁便會被霉菌污染。而關于這種塑料膜，如果不是食品級的材料，在高溫下會分解出有害物質。

4. Coating paper: Generally everyone calls it that way, but in fact, it's an inner polyethylene plastic film. A lot of paper cups have been replaced by paraffin wax with film-spraying paper. But without paraffin, the outer wall of the "protective" cup may become moldy after dampness, and the inner wall of the folded cup will be contaminated by mold. As for this plastic film, if it is not a food-grade material, it will decompose harmful substances at high temperature.

除此以外，劣質紙杯被爆出含有雙酚A。對部分生活用品中的雙酚A含量進行測定后，結果顯示，試驗用一次性紙杯中的雙酚A含量是一次性塑料杯的30倍，雨水里的雙酚A含量是飲水機里純凈水的5倍多。

In addition, inferior paper cups were exploded containing bisphenol A. The content of bisphenol A in some household articles was determined. The results showed that the content of bisphenol A in disposable paper cup was 30 times as much as that in disposable plastic cup, and the content of bisphenol A in rainwater was more than 5 times as much as that of pure water in drinking machine.
