The Selection Guide Of Kids Bottle -How To Distinguish And Choose The Right Material

- Apr 04, 2021-

A large number of parents generally only care about the capacity, appearance, and price of the cup when purchasing a children's water cup, and seldom pay attention to the material of the cup. In fact, some water cups with poor materials, although good in appearance and colorful, can attract the attention of parents or babies, they will have a bad effect on children's health. For example, some plastic water cups will decompose in a high-temperature environment. Such decomposition is very subtle in our daily lives, but it does exist. The toxic substances decomposed by plastics are mainly dioxins and bisphenol A. These two substances will not be absorbed by the human body but will be deposited in the human body. When they accumulate to a certain extent, they will have adverse effects on the human body. Therefore, children's drinking bottles are related to children's health, and mothers need to master purchasing skills. Generally speaking, the purchase of children's water cups will consider seven points including material, applicable age, style, scale, handle, leak-proof, and sterilization. This paragraph will mainly analyze the advantages and disadvantages of different kinds of kids' bottles from the point of material. 


Glass tumbler 

Among cups of all materials, glass is the healthiest. The glass cup does not contain organic chemicals during the firing process. When people drink water or other beverages from the glass cup, they don't have to worry about the chemicals being drunk into their stomachs. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the wall of the cup, so it is the healthiest and safest to drink water from the glass for the baby. However, easily broken is the primary disadvantage of the glass. If the baby cannot hold it stable in his hand, it is easy to break. Besides, the glass material has strong thermal conductivity, and it is easy for users to burn themselves accidentally. If the water temperature is too high, it may also cause the cup to burst. So it is necessary to avoid holding boiling water as much as possible.


Enamel mug 

An enamel cup is a kind of ware with metal enamel on the inside and outside, which is not easy to break. Nonetheless, the porcelain on the surface of the enamelware is composed of sodium silicate and metal salt, which contains a lot of lead, and toxic metal elements such as bismuth, cadmium, and antimony. Storing or drinking coffee with enamelware, which will easily lead the enamelware to precipitate. Citrus acidic beverages have the same effect as hot coffee. Therefore, acidic beverages storing or drinking with enamelware will also increase the precipitation of lead in the enamelware. Long-term use will cause chronic lead poisoning in the human body.


Ceramic cup

The color of the ceramic cup is bright and beautiful, and the shape is also various. The inner wall of the colorful ceramic cup is coated with glaze. When the cup is filled with boiling water or a beverage with high acidity and alkalinity, the lead and other toxic heavy metal elements in these pigments are easily dissolved in the liquid. If people drink it with chemical substances, it will cause harm to the body.


Stainless steel cup 

Stainless steel is made of iron-chromium alloy mixed with trace metal elements such as nickel, molybdenum, titanium, and manganese. Due to its good metal properties and greater corrosion resistance, the made appliances are beautiful and durable. However, it has been confirmed that many metal elements such as chromium, nickel, molybdenum, cadmium, manganese, and titanium. and their compounds have different properties and various degrees of harm to human health. If used improperly, the trace metal elements in stainless steel will also slowly accumulate in the human body and when the accumulated amount reaches a certain limit, it will endanger human health, so individuals ought to be aware of metal poisoning.


Paper cup

Paper cups are portable, non-absorbent, and do not pollute the environment as other materials. It is more suitable for traveling and serving guests at home. It is one-time use, not fragile, eliminating the trouble of cleaning. Nevertheless, disposable paper cups only look hygienic and convenient, but the product's actual qualification rate cannot be judged. Whether it is clean and hygienic, it cannot be recognized with the eye. From the perspective of environmental protection, disposable paper cups should be used as little as possible. Some paper cup manufacturers add a large amount of fluorescent whitening agents to make the cup look whiter. And this fluorescent substance can cause cell mutations, and once it enters the human body, it will become a potential carcinogenic factor. Secondly, those unqualified paper cups are generally soft and easily deformed after being poured into water. Some inferiors have poor sealing, the cup bottom is easy to seep, which can easily burn your hands with hot water. In addition, in order to achieve the water barrier effect, the paper cup will be coated with a polyethylene water barrier film on the inner wall. Polyethylene is the safest chemical substance in food processing but it is difficult to dissolve in water and is non-toxic and tasteless. However, if the selected materials or processing technologies are not good enough, the polyethylene may be oxidized to carbonyl compounds during the process of hot melting or applying to the paper cup. Carbonyl compounds are not easy to volatilize at normal temperature, but when hot water is poured into a paper cup, they may volatilize, so people will smell strange smells. Long-term ingestion of this organic compound is harmful to human health.


Plastic cup

Plastic cups own changeable shapes, bright colors and they are anti-wrestling, you can let the baby take it by themselves or take it with you when going out. But plastic is a polymer chemical material, often contains chemicals such as polypropylene or PVC polyvinyl chloride. When plastic cups are used to hold hot or boiled water, these chemicals can easily decompose toxic substances, which can have adverse effects on the human body. In addition, there are many pores in the internal microstructure of the plastic, which hides dirt, and it is easy to breed bacteria if it is not cleaned.
