Why are the juice cups made of glass and plastic instead of stainless steel?

Regarding what kind of water cups are used for drinking juice, I think many people don't usually pay attention to it, and they think it is a trivial matter.

Because with the emergence of a large number of freshly squeezed juices and fruit and vegetable drinks, people only need to buy a cup to drink, and throw away the disposable cup after drinking. To be precise, the topic we are discussing today is aimed at children and the elderly.

In today‘s society, fruit juice is a favorite drink for children. We found that when the elderly take their children out, they prefer to use stainless steel water cups for the children. Because the cup is strong and durable, it also has good heat preservation. If you use a stainless steel vacuum flask to hold hot water, there is no problem, but many elderly people will pour juice directly into the stainless steel water cup for convenience. Occasionally once or twice will not cause harm to children, but long-term use of stainless steel water cups for juice will cause harm to children.

First, the juice contains plant acid. Both freshly squeezed juices and barreled juices purchased in supermarkets contain plant acid, which is not as mild as people think. The inner wall of the stainless steel water cup is usually electrolyzed, and long-term use of the stainless steel water cup for juice will corrode the electrolytic layer. After corrosion, the metal elements will fuse with the juice, causing the heavy metal content of the juice to seriously exceed the standard.

Secondly, use plastic cups and glass water cups for drinking juice. Due to the relationship between the materials, the water cups of these two materials are mostly transparent or semi-transparent. After drinking, you can clearly see the juice residue, which will make people clean it in time when they notice. However, because the stainless steel water cup is opaque, it will cause people's negligence, can not be cleaned in time, or cleaned incompletely. In daily life, you will definitely find the experience of mildew in the stainless steel water cup.

In addition, because the stainless steel vacuum flask has thermal insulation properties, the juice in the water cup is more likely to cause the reproduction of microorganisms in the juice due to the thermal insulation performance. So sometimes parents find that their children have diarrhea but can't find the cause.
