We drink water from a water bottle every day, but we often hear something like this: It is not safe to drink hot water with a plastic cup, heavy metals may leak out from a glass or stainless steel water bottle, and disposable paper cups are not healthy... Just want to drink water, how do you feel that you are taking poison? Is it true that using the wrong water cup is equivalent to drinking poison? Which is safer, large stainless steel water bottle or plastic bottle?
Introduction of Plastic Water Cup
People often associate plastic cups with toxic substances, especially when it comes to using plastic cups for hot water, they usually feel that the toxic substances in plastic will penetrate into the water, and drinking such water is harmful to the body. Indeed, some plastic cups cannot be used to hold hot water. So how to see what kind of material the plastic cup is and how to choose it?
Generally speaking, a triangle icon and number are marked on the bottom of a plastic water cup. The different numbers represent different types of plastic products. This logo is mainly used to facilitate classification and recycling. Common plastic products are numbered 1-7, such as those made of PET, such as mineral water bottles and beverage bottles.
The PP material (No. 5) and PC material (No. 7) can be used as a water cup. The former is more heat-resistant and can be heated in a microwave oven; the latter has better mechanical properties, but it is not heat-resistant, and has double decomposition. The possibility of phenol is harmful to infants and young children, and it is still controversial whether adult long-term use will cause cancer. Therefore, if you want to hold hot water, it is best to choose PP plastic cups.
Note: If the plastic cup cracks after long-term use, it must be replaced in time. Because the cracks show that the material of the plastic cup may begin to decompose, and the cracks are also easier to breed bacteria, which is harmful to health.
Introduction of stainless steel water bottle
Stainless steel is divided into food grade and industrial grade. In order to increase the stability of the container, food grade stainless steel is added with metal elements such as chromium and nickel, which is not easy to be corroded by acid and alkali. The iron element in industrial-grade stainless steel is very active and can easily reacts with acidic substances. Therefore, as long as it is a qualified food-grade stainless steel water cup, it can be used with confidence without worrying about the leakage of heavy metals.
Stainless steel is relatively stable in nature, but common acidic beverages may affect it, so it is not recommended to use insulated kids water bottle to hold cola and other carbonated drinks for a long time. If you want to choose stainless steel water cups, then you must look for 304 stainless steel Water cup, generally speaking, 304 stainless steel will not harm the human body. At the same time, the lightweight travel water bottle and personalised insulated water bottle are not only convenient, but the insulation function allows you to drink warm water anytime, anywhere.
Do you now know why you choose stainless steel water bottles instead of plastic water bottles? We recommend you to choose a wellness double wall stainless steel bottle or a vacuum insulated water bottle to guarantee the protection of your health.
