As far as I know, tea bags for making tea on the market are mainly made of three materials: filter tissue paper, non-woven fabric and nylon. Among them, the first two materials are more common. The filter cotton paper is mainly made of imported wood pulp. Although the price is low, it is not resistant to foaming. The non-woven fabric is moisture-proof and breathable, easy to degrade, non-polluting, and moderately priced.
Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers, and are called cloth because of their appearance and certain properties. Because the outer light looks like pearls, non-woven fabrics also have a nice name-pearl canvas. In addition to tea bags used to make teabags, non-woven fabrics are also used in many ways, such as shopping bags, bed sheets, disposable masks for medical and hygiene, and so on.
Polypropylene (referred to as PP) is the main fiber used in the production of non-woven fabrics. It is a colorless, odorless, non-toxic, translucent solid substance with a service temperature range of -30 to 140 °C. The non-woven products made of it are produced with FDA food-grade raw materials, do not contain other chemical components, are non-toxic, odor-free, and non-irritating.
In view of these characteristics, non-woven tea bags are non-toxic and non-irritating. When brewed in hot water at 100 degrees Celsius, the tea bags will not release any toxic and harmful substances, so they are very safe and environmentally friendly. Moreover, the non-woven fabric can be degraded, and there will be no environmental pollution problem.
Of course, the premise is that the non-woven tea bags are produced by regular manufacturers, and you also need to pay attention to avoid buying fake and inferior products when purchasing. It is not recommended to buy teabags with no description on the tea bag material. The non-woven tea bag is thin and transparent. When making tea, you can see the process of tea slowly stretching in the water through the almost transparent non-woven fabric, which is full of fun and appreciation.
