In daily life, many people like to drink a variety of drinks with disposable paper cups, which are not only convenient, but also clean and sanitary. But there are rumors on the Internet that the disposable paper cup that looks very clean is actually not clean, and even using it to hold hot water will produce carcinogens, seriously threatening the health of the user, is this really the case?
According to the Health Times report, the commonly used disposable paper cup is a paper-plastic cup, the outside is a layer of paper, and the inside is a layer of coated paper, which is actually a plastic film called polyethylene. This paper plastic cup has many risk factors: first, there may be problems with the hygiene of the outer layer of paper, if the outer layer of water, it will form mold, when the paper cup is superimposed together, it will lead to its inside being polluted; Secondly, the outer printing ink may not meet the standard, many ink components contain benzene and toluene, benzene is a recognized carcinogen; Third, some paper cups may be made of waste paper, in order to make the paper cup look more white, in the production, the manufacturer will use bleach and even phosphor, these substances will harm human health, so the more white the paper cup may be unsafe.
So, does hot water in disposable paper cups produce carcinogens? Zhang Qingwen, deputy director of the National Paper Quality Supervision and Inspection Center, said in an interview with China Quality News that under normal circumstances, the internal polyethylene plastic film that meets the requirements of the standard will decompose above 200 ° C, so it is safe to use this paper plastic cup to hold hot water. Therefore, the most important thing we should pay attention to is the quality of disposable paper cups, and disposable paper cups produced by regular manufacturers should be purchased.
What do you need to pay attention to when buying disposable paper cups? \"Chongqing Morning Post\" mentioned, first of all, to understand the scope of disposable paper cups, is suitable for cold drinks or hot drinks; Secondly, choose a paper cup with a certain thickness and a stiff body, gently squeeze both sides of the paper cup, and the cup body is too soft and broken when torn is mostly unqualified products; Once again, smell whether the disposable paper cup has an odor, if the odor is large, it means that the use of inferior ink is likely; Finally, it is best not to choose a paper cup that is too white in color, which may have added chemicals such as fluorescent agents. In addition, it is best to rinse with water before using disposable paper cups to reduce the attachment of harmful substances and bacteria.
Disposable paper cups commonly used by people, outside is a layer of paper, the inside is a layer of coated paper, if the material or process selected in the production is not passed, it will be dangerous to people
Some illegal business in order to reduce the wood, the use of industrial paraffin wax to do the inner membrane of the cup, industrial paraffin harmful substances to the human body, will cause harm to the human nervous system and hematopoietic system
1, disposable paper cups containing boiling water hidden potential carcinogens
Those unqualified paper cups are generally very soft, easy to deform after pouring boiling water, some paper cups are poorly sealed, the bottom of the cup is easy to seep water, which is easy to make hot water scalded hands; What's more, when you gently touch the inside of the paper cup with your hand, you can feel the fine powder on it, and the touch of your fingers will turn white, which is typical of poor quality paper cups.
2, when the water is filled with plastic cups, toxic chemicals are easy to dilute into the water, and the internal microstructure of the plastic has a lot of pores, which hide dirt, cleaning is not clean will easily breed bacteria. Therefore, when purchasing plastic cups, be sure to choose a cup made of edible grade plastic that meets national standards.
3, metal cup drinking coffee will dissolve
Metal cups, such as stainless steel, are more expensive than ceramic cups. The metal elements contained in the enamel cup composition are usually relatively stable, but in an acidic environment, it may dissolve out, and it is not safe to drink acidic drinks such as coffee and orange juice.
Disposable paper cups and plastic cups, of course, can hold hot water ah, as long as the quality of disposable cups pass, there will be no problem, mainly worry about not being hot, disposable paper cups and plastic cups are generally not insulated.
The layer of plastic film on the inner wall of the paper cup, specifically, should be polyethylene, some will be coated with paraffin, both are very safe, rest assured. Polyethylene temperature tolerance is still very strong, do not need to worry about it will melt out toxic substances, not to mention paraffin wax, paraffin melting point can reach more than 200 degrees.
The surface of the cold drink paper cup should be sprayed with wax or dipped wax treatment, between 0 ° C and 5 ° C, this wax is very safe, but if it is used to hold hot drinks, as long as the temperature of the water exceeds 62 ° C, the wax will melt, and the paper cup will absorb water and deform. The melted paraffin has a high content of impurities, especially the polycyclic aromatic hydrocarbons contained in it, which are possible carcinogenic substances, and enter the human body with the beverage, which will harm people's health. The surface of the hot drink paper cup will be glued with a special film, not only good heat resistance, but also non-toxic and harmless.
Disposable cups are divided into paper, plastic, but the difference is that people in the paper cup in the hot water, drink once, if this back and forth to follow the rules of drinking, the paper disposable cups distributed substances dangerous to health.
Do you ask the danger of filling a disposable cup with boiling water?
I think the disposable cup should not be filled with boiling water as far as possible because the disposable cup let go of the water, it may be easy to boil the bottom of the cup, which will produce dangerous disposable cups as far as possible to put cold water or warm water to use, and there are some disposable cups have wax components if once the water is boiled, the wax on the cup will dissolve into the water is not safe
A disposable cup containing boiling water is slightly toxic. We all know that disposable cups, it and the barrel of instant noodles, are the inner wall will have a layer of wax-like things, the purpose is to hold water after waterproof penetration, if it is used in warm water or cold water, there is no relationship, but once the use of boiled water, the layer of wax-like things on the inner wall will be precipitated in a small amount at high temperature, long-term use he will remain in the body. Cause some harm to human body.
Plasticizers are often added to plastic cups, which contain some toxic chemicals, when plastic cups are filled with hot water or boiling water, toxic chemicals are easy to dilute into the water, and the internal microstructure of the plastic has a lot of pores, which hide dirt, cleaning is not clean will be easy to breed bacteria.
Plastic cups, which belong to high polymer, are not good for the body. However, drinking cold water or cold drinks will not be too harmful, if it is hot water or hot drinks, it will react with plastic cups, which may produce harmful substances to the human body, so try not to use plastic cups to drink hot water.
Disposable plastic cups can drink hot water, generally not harmful to the body, however, some poor quality plastic cups can not be loaded with hot water. The harm of using disposable plastic cups as above, it is recommended that you usually try not to use plastic cups to drink hot water.
Hot water in disposable plastic cups! Is it really toxic

Mainly because inferior plastic cups generally contain plasticizers, which is a harmful chemical, the cup into hot water, harmful substances will dissolve into the water, resulting in a certain harm to the human body; In addition, there is a certain gap in the plastic, there will be stains remaining in it, and it will also have an adverse effect on the human body when integrated into hot water.

Therefore, less plastic cups should be used in life, and glasses or stainless steel cups should be used as much as possible
If you must use a disposable paper cup to hold hot water, the first cup should not be drunk. The reason is that the high temperature of hot water will dissolve other harmful substances such as paraffin wax or bleach on the inner wall of the paper cup in water, and these harmful substances will enter the body with the water, and the accumulation of time will harm people's health and even increase the risk of cancer.
