At present, the water bottles on the market are mainly divided into glass, plastic, aluminum and stainless steel water bottles according to the materials. Glass water cups are fragile, bulky and not easy to carry.
Plastic water bottles can also be divided into PP and PC materials. Common water bottles, space cups and baby bottles are made of PC materials, which can easily release toxic bisphenol A (BPA) when heated or directly exposed to the sun. BPA is especially dangerous for infants. Many countries in Europe and the United States have listed BPA in the list of banned chemicals. Only PP material (with BPA Free Logo) can be used safely.
Aluminum water bottles are made of high-purity aluminum and coated with epoxy resin on the inner wall. Modern medical research shows that aluminum accumulates too much in human body, which can cause mental decline, memory decline and Alzheimer's disease. Therefore, people, especially teenagers, should try to reduce the use of aluminum tableware and cooking utensils.
The stainless steel water bottle is made of high-quality 18 / 8 medical grade stainless steel (i.e. 304 stainless steel). The thickness of the bottle is 0.4mm to 0.5mm. The inner wall of the bottle is free of any coating, harmful chemicals and toxins. It is a preferred alternative to traditional plastic and aluminum water bottles. At present, 201 stainless steel (including 3.5-5.5% nickel) is used in the market, and its corrosion resistance is far worse than 304 stainless steel (including 8-10% nickel), and the price is only half.
There is not much difference between the weight of stainless steel water bottle and aluminum water bottle. There is a stamping line in the stainless steel water bottle, and the aluminum water bottle is not easy to wash because of its inner coating.
