Paper bowl plastic bowl which is more harmful? You know, behind this seemingly clean disposable paper bowl, there are actually huge health risks hidden. So there are always people on the Internet who suggest that our commonly used plastic bowls are poisonous. Which is more harmful?
Paper Bowl Plastic Bowl Which is more harmful 1 Not all disposable paper bowls are harmful, only paper bowls 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.

Inferior imitation porcelain bowl
Imitation porcelain bowls, also called melamine tableware, look like porcelain bowls, but they are cheaper than real ceramics and have better heat insulation effect. They are standard in many canteens and small restaurants. Because imitation porcelain bowls are not easy to break and cut hands, and businesses will print colorful cartoon patterns, many families will give them to their children.
Qualified melamine tableware is safe, but some illegal enterprises use cheap urea-formaldehyde resin for non-food packaging instead of processing, which leads to the increased risk of these tableware. High levels of formaldehyde will be released above 80℃. Long-term use will cause digestive tract and respiratory diseases, blood diseases, and even more serious cell canceration.
Disposable paper bowl
The disposable paper bowl looks white and clean, because the fluorescent whitening agent is added in the paper bowl, which is not easy to decompose. After being absorbed by the human body, it will accumulate in the human body, damage the blood system, increase the burden on the liver and cause organ damage.
In order to enhance the waterproof effect of paper bowls, paper cups are usually coated with a layer of wax. When the temperature exceeds 60℃, the wax will melt and release a toxic substance called polycyclic aromatic hydrocarbons, which is easy to form carcinogens under the action of enzymes, which is harmful to human health.
Aluminium bowl
Aluminum lunch boxes have been accompanied by a generation of young people because of their non-toxicity, portability, durability, high quality and low price. However, excessive accumulation of aluminum in human body will accelerate human aging and have a negative impact on memory.
Aluminum tableware is not suitable for cooking acidic and alkaline foods, nor for storing meals and salty foods for a long time.
Glazed ceramic bowl
Colored glazed tableware looks good, but beware of the harm caused by colored glaze, especially "glazed color". The glaze is bright. When encountering acidic substances or drinks, the lead in the glaze will dissolve in food and enter the human body, which is harmful to human health.
The patterns of painted pottery bowls are generally divided into "over-glaze color" and "under-glaze color". The pattern of "over-glaze color" is brighter than that of "under-glaze color". The pattern of over-glaze color will feel concave and convex when touched by hand, but the under-glaze color does not. Under-glaze color is more suitable for tableware than over-glaze color.
Plastic bowl
Plastic bowls are not resistant to high temperature, and are easy to deform or even melt when exposed to high temperature, and then chemically react with the food in the bowl to generate harmful substances, which are harmful to human health after eating.
Plasticizers are often added to plastic bowls. When plastic bowls meet boiling water or hot water, toxic chemicals are easily diluted into water, which directly harms human health. Moreover, there are many pores in the internal microstructure of plastic, which contain dirt. If it is not cleaned properly, bacteria can easily breed.

Long-term use of plastic bowls is harmful to health. Plasticizers are often added to plastics because they contain some toxic chemicals. When hot water or boiled water is filled in a plastic bowl, toxic chemicals are easily diluted into water, and there are many small holes in the internal microstructure of plastic, which contain dirt. If it is not cleaned properly, bacteria can easily breed.
Suggestion: When purchasing plastic bowls, you must choose cups made of food-grade plastic that meet the national standards. Among all bowls made of materials, the glass bowl is the healthiest, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the cup wall, so people use the glass bowl is the healthiest and safest.
Is the plastic bowl poisonous?
About "Is the plastic bowl poisonous?" An online survey found that 99% of netizens think it is poisonous and very harmful to the health. Only 1% netizens think it is non-toxic, and all edible items have been tested for non-toxicity.
So what is the truth? According to a survey report released by the Consumer Council of Hong Kong, nearly 30% of tableware that can be heated by microwave ovens is toxic. When they overheat, they will release a chemical called plasticizer, which will destroy the endocrine system of the human body. Long-term intake of plasticizer will also damage the liver and kidney of human body and affect the development and growth of children.

What material is good for making plastic bowls?
Use PP material, because PP material is low in cost, easy to form, tasteless and non-toxic (there is also a kind of food-grade PP material, which is itself a container for food). And PP material has many excellent characteristics, such as; High temperature resistance, excellent weather resistance, good toughness, etc. PP is a nonpolar compound, which is very stable to polar solvents, such as alcohol, phenol, aldehyde, ketone and most carboxylic acids.
