What kind of custom water bottles is better for drinking water?

Glass cup

Among all materials, the glass is relatively safe. The glass water cup is usually made of inorganic silicate, which is fired at a high temperature of more than 600 degrees. Because of its relatively stable chemical composition, no harmful substances are generated during the firing process; and the glass surface is smooth and easy to clean. Bacteria and dirt are not easy to breed on the wall of the cup.

Note: The first time you use the glass, you will be afraid that the boiling water will cause it to burst. You should pour a little hot water first, shake it gently to preheat the glass, and then pour hot water to use.

Plastic cup

Many people worry that plastic water cups will cause cancer. In fact, it is relatively safe to choose a brand that meets national quality inspection standards. The PP cup has good heat resistance, the melting point is as high as 167℃, and the chemical properties are relatively stable. It is the only plastic material that can be put into the microwave oven; while the PC cup cannot be filled with hot water and should not be exposed to sunlight, because high temperature may cause this material release toxic BPA.

In addition, although the surface of the plastic cup looks smooth, there are actually many voids, which are easy to contain dirt and dirt; and the plastic cup is easier to absorb dust and bacteria.

1. Ceramic cup with no color glaze and colorless inner wall: The main component of the ceramic water cup is clay, which will form a layer of glaze on the surface of the clay after high temperature calcination. Under normal circumstances, there are no harmful substances in this layer of glaze. Drinking hot water and tea are good choices.

2. Ceramic cup with underglaze color: This type of cup is painted with paint first, and then calcined at high temperature. At this time, the paint is stored under the glaze. Even if hot water is brewed, harmful substances will not leak out.

Stainless steel cups are corrosion-resistant, wear-resistant, and not fragile. They are often used as insulation cups and become the first choice for modern cups. However, because it is an alloy product, it may contain a lot of heavy metal substances. If used improperly, these substances are easy to seep out or undergo chemical reactions, which may produce harmful substances.

Tips: Do not use stainless steel drinking cups for acidic beverages, such as juice, coffee, carbonated drinks, etc.; do not hold soy sauce, vinegar, vegetable soup, tea, etc. for a long time. When washing stainless steel coffee cup, do not use strong alkaline or strong oxidizing chemicals, such as soda, bleach, etc.Disposable cup

It is an inner polyethylene plastic film with relatively high safety; plastic cups used in milk tea shops and coffee shops are It is made of PET. As long as it is not heated at high temperature, harmful substances will not leak out, so it can be used with confidence.

Note: Be sure to look for safety products with the SC mark when purchasing. However, it is not recommended to use disposable products from an environmental perspective.
