Why choose corn fiber tea bag?

What are the requirements for the inner bag when we buy tea bags? It is better to use corn fiber tea bag (the cost of corn fiber tea bag is higher than that of PET nylon). Because corn fiber is a synthetic fiber that is converted into lactic acid by fermentation and then polymerized and spun. It is natural, environmentally friendly and degradable, and can withstand 130 celsius degree high temperature. Even using boiling water at 100 degrees will not be a problem. Moreover, corn fiber is degradable and beneficial to the environment.

So how to identify the material of the tea bag you bought? As mentioned above, tea bags are currently made of non-woven fabrics, nylon, corn fiber and other materials.

Non-woven tea bags are made of polypropylene. Many traditional tea bags are made of non-woven fabrics. If they meet the standards, their safety can also be guaranteed. The disadvantage is that the perspective of tea bag is not strong and the water permeability is not good. There are harmful substances in the production process of some non-woven fabrics, which may be released during the brewing process.

Nylon tea bag has strong toughness and is not easy to tear, and the mesh is large. The disadvantage is that when brewing tea, if the water temperature exceeds 90 ℃ for a long time, it is likely to release harmful substances. The easiest way to make nylon tea bags is to burn them with a lighter. The nylon bags are black after burning. It is not easy to tear.

In the same way as corn fiber, the color of ash after burning is the color of some plants, and the corn fiber is easy to be torn.
