Which tea bag is the best? !
There are basically three common materials for tea bags: non-woven fabrics, nylon, and corn fiber.
1. Non-woven tea bags
Non-woven fabric refers to polypropylene (PP), which is the same material as mask fabric.
2. Nylon tea bags
Nylon is a petrochemical product. There are many categories. It is very common in life, so I won't talk about it.
Both of the above can be edible grade, otherwise it would not be possible to make tea bags. The better tea bags I bought in Southeast Asia were all nylon bags. If they were popular ones from Lipton, they would have more non-woven fabrics. Even if you use the best materials, there is no way to solve the problem of high temperature and long-term soaking. Microplastics will be released. If they are inferior, they will release more toxic substances. Therefore, you can use these two. If you really want to use it, then you must have a reliable channel to buy high-quality tea bags. If it is unavoidable, at least be less poisoned. When you use it, try to rinse it out and take it out, not for a long time. High soaking.
3. Corn Fiber Tea Bags
As for corn fiber, it is the best and least among the three materials. This corn fiber is not the fiber we usually say when we eat, and it is not the ones you see in the leaves of corn silk, but a kind of polylactic acid (PLA). The biodegradable material is also called "corn plastic" in the United States, also called polylactic acid fiber, PLA fiber. The unit price is much more expensive than the other two, at least twice. Moreover, the current global production is very high. Now that the world has banned plastics, the demand for PLA is higher, and the production capacity is still increasing. It is estimated that it will be better in three or five years, but in fact, the production capacity is still far from enough.
Most of the corn fiber tea bags on the market are fake. You can tell if you burn them into ashes or into grains.
Therefore, the preferred order of the three tea bags is:
1. Corn fiber (polylactic acid PLA)
2. Other high-quality non-woven fabrics, nylon.
