Most of the tea bags currently on the market are made of several different materials such as non-woven fabrics, nylon, and corn fibers. Non-woven tea bags. Non-woven fabrics are generally made of polypropylene (pp material) pellets as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. Many traditional teabags use non-woven materials, which are relatively low in cost. If the non-woven materials meet the quality standards, they are relatively safe. The disadvantage is that the permeability of tea and the visual permeability of tea bags are not strong. In addition, non-woven fabrics are not made of natural materials, and there are some harmful substances in the production process of some non-woven fabrics, which may be released during hot water brewing. Nylon material tea bag. In recent years, it has become more popular, especially fancy teas are mostly made of nylon tea bags. The advantages are strong toughness, not easy to tear, and larger tea leaves can be placed. The whole piece of tea leaves will not damage the tea bag when it is stretched. The mesh is larger, which makes it easier to brew the tea flavor. Seeing the shape of the tea leaves in the tea bag is one of the reasons why fancy teas use nylon tea bags in large quantities. The disadvantage is that the industrial feeling is relatively strong, and harmful substances may be released when the temperature exceeds 90°C for a long time when brewing tea. One is PLA (polylactic acid for short) corn fiber cloth imported from Japan. One is corn fiber cloth imported from the UK. Both raw materials are natural and environmentally friendly corn fiber. PLA corn fiber cloth imported from Japan saccharifies corn starch, ferments it into high-purity lactic acid, and then forms polylactic acid through certain industrial manufacturing procedures to realize fiber reconstruction. The fiber cloth is meticulous and balanced, and the meshes are arranged neatly. In contrast, the visual permeability is also very strong, and the tea bag is relatively straight, so you can clearly see the tea leaves in the tea bag before soaking in water. The corn fiber cloth imported from the UK seems to have a stronger sense of natural plant material, with some irregular fiber lines and fine mesh, which cannot be seen by the naked eye. The visual permeability of the tea bag is not strong without soaking in water. , It is difficult to see the tea leaves in the tea bag clearly. After soaking in water, the visual permeability will be greatly improved. The tea bag has a high degree of crispness, and its appearance is relatively inferior to that of PLA corn fiber cloth tea bags imported from Japan. PLA corn fiber cloth tea bags imported from Japan, although the appearance is better, but due to the larger mesh of the tea bags, after brewing, the tea leaves are almost completely soaked in hot water, and the tea quality will seep out very quickly and evenly. The British corn fiber cloth tea bag is precisely because its mesh is extremely fine, and even the tea powder cannot seep out. After brewing, the tea leaves will stretch and expand in a relatively closed environment, which has a similar effect to brewing in a "flushing can" or "covered ou", and the tea quality can also slowly seep out in a controlled manner, so that the tea can be maximized. Guarantee the quality of tea.
