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、纸:许多厂家为了利益扩大化，并不会用食品级的木浆纸。以次充好的比比皆是。如果纸质不佳(回收利用的废纸)便用漂白粉和荧光增白剂，这是普通消费者无法分辨的。

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:在生产成本决定一切的年代，关于印刷油墨的标准似乎不见效。因此含有苯和甲苯的油墨也充斥在市场里。对于印刷过的纸杯套叠以后，油墨就很可能污染纸杯内壁。

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、工业石蜡:纸杯如果不做防水处理，那还能装水吗?因此有一种纸杯是石蜡泡过的。蜡含有一种叫"多环芳烃"的有害物质，而蜡的熔点是40°，且油可以溶解蜡，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、淋膜纸:一般大家都是这么叫的，但其实是内聚乙烯塑料膜。很多纸杯用淋膜纸代替了石蜡。但是没有了石蜡的"保护"杯子外壁在受潮后可能会发霉，套叠起来的杯子，内壁便会被霉菌污染。而关于这种塑料膜，如果不是食品级的材料，在高温下会分解出有害物质。

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 A lot of paper cups have been replaced by paraffin wax with film-spraying paper.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，劣质纸杯被爆出含有双酚A。对部分生活用品中的双酚A含量进行测定后，结果显示，试验用一次性纸杯中的双酚A含量是一次性塑料杯的30倍，雨水里的双酚A含量是饮水机里纯净水的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.
