Most of the tea bags currently on the market are made of several different materials such as non-woven fabrics, nylon, and corn fiber.

Non-woven tea bags: Non-woven fabrics generally use polypropylene (PP material) pellets as raw materials. Many traditional tea bags use non-woven materials, which are relatively low-cost. The disadvantage is that the tea water permeability and the visual transparency of the tea bag are not strong.

Nylon material tea bag: It has become more popular in recent years, especially fancy teas that mostly use nylon tea bags. The advantage is that it has strong toughness and is not easy to tear. It can hold larger tea leaves. The tea bag will not be damaged when the whole tea leaf is stretched out. The mesh is larger, making it easier to brew the tea flavor. It has strong visual permeability and can clearly distinguish the tea bag. Seeing the shape of the tea leaves in the tea bag,

Corn Fiber Tea Bags: PLA corn fiber cloth saccharifies corn starch and ferments it into high-purity lactic acid. It then undergoes certain industrial manufacturing procedures to form polylactic acid to achieve fiber reconstruction. The fiber cloth is fine and balanced, with neatly arranged meshes. It looks and feels completely good. Compared with nylon materials, it has strong visual transparency.

There are two ways to distinguish between nylon material tea bags and corn fiber cloth tea bags: one is to burn them with fire. Nylon material tea bags will turn black when burned, while corn fiber cloth tea bags will feel a bit like burning hay and have the aroma of plants. The second is to tear it hard. Nylon tea bags are difficult to tear, while Heat Sealing Corn Fiber Tea Bags can be torn easily. There are also a large number of tea bags on the market claiming to use corn fiber cloth tea bags, but they actually use fake corn fiber, many of which are nylon tea bags, and the cost is lower than corn fiber cloth tea bags.
