有的纸杯生产厂家为了使杯子看上去更白,加入了荧光增白剂,这种荧光物质可使细胞产生变异,一旦进入人体就会成为潜在的致癌物质.为了使纸杯达到隔水效果,生产中会在内壁涂一层聚乙烯隔水膜.聚乙烯是食物加工中朂安全的化学物质.但如果所选用的材料不好或加工工艺不过关,在聚乙烯热熔或涂抹到纸杯过程中,可能会氧化为羰基化合物.羰基化合物在常温下不易挥发,但在纸杯倒入热水时,就可能挥发出来,所以人们会闻到有怪味.长期摄入,对人体一定有害.

In order to make the cups look whiter, some paper cup manufacturers add a large of fluorescent whitening agents, which can mutate cells and become potential carcinogens if they enter the human body. In order to make the paper cups be water-proof, a layer of polyethylene water-proof film will be coated on the inner wall. Polyethylene is the safest chemical substance in food processing. However, if the raw materials are not good or the processing technology is not qualified, the polyethylene may be oxidized to carbonyl compounds during hot melting or coating on the paper cup. Carbonyl compounds are not easy to volatilize at normal temperature, but they may volatilize when pouring hot water into a paper cup, so people will smell odor. Long term ingestion is harmful to our body.

The inner wall of disposable paper cup does have a smooth layer. A small part of the coating is paraffin, and most of it is polyethylene that is really safe. 

According to the standard, paraffin is a safe material that can come into contact with food. The melting point of paraffin is very high, which can reach more than 200 degrees.

If it melts in hot water as rumor, you can prompt see that wax oil is floating on the water.PVC that we often use is also high temperature resistant, and the cost is not high.

High purity is its another prominent feature and almost does not contain any chemical additives, such as plasticizer and bisphenol A.
