1. Nylon tea bag
In recent years, it has become more popular, especially for fancy tea, mostly nylon tea bags are used. The advantage is that it has strong toughness and is not easy to tear. It can be placed in larger tea leaves. The whole piece of tea will not damage the tea bag.
Larger, easier to brew the tea flavor, with strong visual permeability, you can clearly see the shape of the tea leaves in the tea bag, which is one of the reasons why fancy tea uses a large number of nylon tea bags.
The disadvantage is that the industrial feeling is relatively strong, and it may release harmful substances when it exceeds 90 °C for a long time when brewing tea.
2. Non-woven tea bags
Non-woven fabrics are generally made of polypropylene (pp material) pellets as raw materials, and are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing and coiling. Many traditional tea bags use
Using non-woven materials, the cost is relatively low, if the non-woven materials meet the quality standards, it is also relatively safe.
The disadvantage of non-woven tea bags is that the permeability of tea water and the visual permeability of tea bags are not strong. In addition, non-woven fabrics are not made of natural materials, and some non-woven fabrics have some harmful substances in the production process, which can
can be released during hot water brewing.
3. Two types of corn fiber cloth tea bags
One is PLA (polylactic acid for short) corn fiber cloth imported from Japan. The corn starch is saccharified, fermented into high-purity lactic acid, and then formed into polylactic acid through a certain industrial manufacturing process, to achieve
The fiber is rebuilt, the fiber cloth is meticulous and balanced, the meshes are arranged neatly, and the look and feel can be compared with the nylon material. The visual permeability is also very strong, and the tea bag is also relatively crisp. the situation of tea.
One is corn fiber cloth imported from the UK. It seems that the texture of natural plants is stronger, there are some irregular fiber patterns, the mesh is fine, and the mesh is not visible to the naked eye.
Under these conditions, the visual permeability of the tea bag is not strong, and it is difficult to see the condition of the tea leaves in the tea bag. After soaking in water, the visual permeability will be improved. The degree of stiffness of the tea bag is not high, and its appearance is relatively inferior to that of the PLA corn fiber cloth tea bag imported from Japan.
The PLA corn fiber cloth imported from Japan and the corn fiber cloth imported from the United Kingdom all use natural and environmentally friendly corn fiber as raw materials. Compared with nylon tea bags and non-woven tea bags, I personally think that
Safer, it is recommended to look for corn fiber cloth tea bags when purchasing tea bags.
