Not all disposable paper bowls are harmful, only those that do not meet the national standards may be harmful to human body. Many restaurants have disposable paper cups, paper bowls and other tableware, and many customers think it should be at least more hygienic than plastic cups and bowls. In fact, some paper tableware is unsafe and unsanitary for two main reasons:
1, health indicators are unqualified.
The unqualified hygienic index is mainly the unqualified evaporation residue. Such as calcium carbonate, talcum powder, paraffin wax, liquid additives and the like. They are all illegally added in the production process of disposable paper bowls. If users use this paper tableware for a long time, a large number of unknown substances may enter the human body, causing harm to the body, which may reduce human immunity, lead to gallstones, kidney calculi, constipation, blood system diseases and other chronic diseases, and even cause cancer.
The unqualified sanitary indicators also indicate that the decoloration test is not up to standard. There are clear requirements for pattern printing in national standards. Take a paper cup as an example, there should be no printed patterns within the range of 15 mm from the mouth of the cup and 10 mm from the bottom of the cup. In order to reduce the production cost, some disposable paper bowl manufacturers use unqualified ink for pattern printing. When consumers use paper cups, the colored parts of paper cups will come into contact with the sweat on their lips or hands. Unqualified ink often contains benzene and toluene, which will be harmful to human health.
2, the use performance is unqualified
The unqualified items of disposable paper bowls mainly include leakage performance, sensory index and compressive strength. Han pointed out that the unqualified leakage performance and compressive strength will directly affect the use of consumers; The problem of unqualified sensory indicators is that the distance between printing and cup mouth and cup bottom does not meet the standard requirements, which may lead consumers to directly contact the printing parts and ingest substances harmful to human body during use.
2. Which is safer, a disposable paper bowl or a plastic bowl?
The standards of disposable paper bowls and plastic bowls are different. If they don't meet the standards, there will be potential safety hazards, so we can't absolutely say which one is safe.
The inner wall of disposable paper bowls commonly used in the market is coated paper, that is, the inner polyethylene plastic film. Now many paper cups use coated paper instead of paraffin. However, without the "protection" of paraffin wax, the outer wall of the cup may be moldy after being wetted, and the inner wall of the nested cup will also be contaminated by mold. As for this kind of plastic film, if it is not a food-grade material, it will decompose harmful substances at high temperature.
Now commonly used disposable plastic bowl materials are PP and PS. PP is resistant to high temperature and can be used in microwave. Generally, the locked crisper on the market is made of PP .. PS is not resistant to high temperature, so it is often used for cold drink packaging. In the manufacturing process, disposable plastic bowls are more sanitary than paper bowls, because the manufacturing process of plastic is simple, and it is packaged immediately after molding and cooling at high temperature. Disposable paper bowls are printed, paper-cut, pasted, rolled and curled, which are easy to be polluted during the period.
Therefore, whether it is a paper bowl or a plastic bowl, it must meet the corresponding standards before it can be used with confidence.
