There are many kinds of drink bottles for our daily drinking water, which are mainly reflected in the difference in material. Common ones are glass bottles, ceramic mugs, paper cups, etc. When we choose, we generally choose according to personal preferences, and some people choose according to health. So, do you know which kind of drinking bottle is healthier in general? What kind of bottle is the healthiest to drink water? Follow Nowest(water bottle manufacturer) to find out.

Glass bottles: practical, safe and anti-explosion

The first choice for drinking bottles should be glass mugs, especially for office and home users. The glass is not only transparent and beautiful, but among all the materials of cups, the glass is the healthiest and safest. The glass is made of inorganic silicates and does not contain organic chemicals during the firing process. When people drink water or other beverages with glass bottles, they do not have to worry about the chemicals being drunk into their stomachs. Moreover, the glass bottle’s surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the wall of the glass, so it is the healthiest and safest for people to drink water. The only thing to note is that the glass is most afraid of thermal expansion and contraction, and the glass bottles with too low temperature should not be filled with hot water immediately to prevent them from bursting.

The glass itself has no color. There are two possibilities for the production of colored glass bottles: A. Natural color. The raw materials for making the glass bottles contain some minerals, which make the glass bottles made colored; B. Most of the colored glass is in the processing and production process to add pigments, and these pigments generally contain heavy metals. But the color cannot be used as a reason for the glass bottle to be faulty.

Plastic bottles: choose food grade plastic

Plastic drink bottles are loved by many people because of their changeable shapes, bright colors, and the characteristics of not being afraid of falling. They are very suitable for outdoor users and office workers. Generally speaking, the bottom of the plastic drink bottle has a mark, which is the number on the small triangle. The common one is “05”, which means that the material of the drink bottle is PP (Polypropylene). The drink bottle made of PP has good heat resistance, the melting point is 170 ° C ~ 172 °C, and the chemical properties are relatively stable. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. But the problem with ordinary plastic drink bottles is widespread. Plastic is a polymer chemical material. When a plastic drink bottle is used to fill hot water or boiling water, the polymer is easily precipitated and dissolved into the water, which is harmful to human health after drinking. Moreover, the internal microstructure of plastic has many pores, which hide dirt, and bacteria will breed if it is not cleaned properly. Therefore, the selection of plastic drink bottles is very important for the selection of plastic materials, and food-grade plastics that meet national standards must be selected. That is PP material.

Ceramic mug: Choosing underglaze color is better 

Colorful ceramic water mugs are very flattering, but in fact there are huge hidden dangers in those bright paints. The inner wall of an inexpensive colored ceramic mug is usually coated with a layer of glaze. When the glazed mug is filled with boiling water or beverages with high acid and alkalinity, some aluminum and other heavy metal toxic elements in the glaze are easily precipitated and dissolved into the liquid. At this time, when people drink liquid with chemical substances, the human body will be harmed. When using ceramic mugs, it is best to use natural color mugs. If you can’t resist the temptation of color, you can reach out and touch the color surface. If the surface is smooth, it means that it is underglaze color or in-glaze color, which is relatively safe; If it is bumpy, nail picking will also be a phenomenon of falling off, which means that it is an on-glaze color, and it is best not to buy it.

Stainless steel bottle: do not hold acidic drinks

The advantage of stainless steel bottles is that they are durable, rust and corrosion resistant. However, stainless steel bottles are alloy products and contain a lot of heavy metal substances, such as nickel, chromium, manganese, etc. If used improperly, these heavy metal substances will be easily released, which is harmful to health. Therefore, in daily use, be careful and don’t use stainless steel bottles for acidic drinks, such as juice, coffee, carbonated drinks, etc.; Also do not store soy sauce, vinegar, vegetable soup, tea, etc. for a long time, because the electrolytes in these foods may be mixed with The heavy metal substances in stainless steel undergo chemical reactions, resulting in the precipitation of heavy metal substances. When washing stainless steel bottles, do not use strong alkaline or strong oxidizing chemicals such as soda, bleaching powder, etc. These substances are also prone to chemical reactions with stainless steel.

Paper cups: Disposable paper cups should be used sparingly

Now, there are still many families and companies that prepare disposable paper cups, which are used by one person and thrown away after use, which is hygienic and convenient, but such a common cup hides many problems. There are three kinds of paper cups on the market now: the first one is made of white cardboard, which cannot hold water and oil. The second is a wax-coated paper cup. As long as the water temperature exceeds 40°C, the wax will melt and release carcinogenic polycyclic aromatic hydrocarbons. The third type is paper-plastic cups. If the selected materials are not good or the processing technology is not good enough, cracking changes will occur during the process of polyethylene hot-melting or smearing on the paper cups, resulting in carcinogens. In order to increase the toughness and stiffness of the cups, plasticizers are added to the paper cups. Hygienic conditions cannot be guaranteed if the dosage is too high or illegal plasticizers are used.

Enamel mug: It should be eliminated decisively after damage

Enamel drinkware is also a good choice. Enamel is a composite material in which inorganic glass materials are melted and solidified on metal at thousands of degrees. Enamel coating on the metal surface can prevent rust so that the metal will not form an oxide layer on the surface when heated and can resist the erosion of various liquids. Enamel products do not contain harmful substances such as lead, are easy to carry and clean, and are widely used as eating utensils and washing utensils in daily life. The enamel mug has a disadvantage. The enamel mug is afraid of bumping, and the surface is prone to damage. Studies have shown that damaged enamel mugs are prone to precipitation of harmful substances when serving drinks, and should be eliminated decisively.


To sum up, the materials of water bottles are glass bottles and ceramic mugs without color glaze, which are the most healthy and safe. Did you choose the right one?
