Will it really contaminate the tea if aluminum bags are placed directly into tea bags? No, aluminum bags that have reached the food grade level can safely store tea. In daily
life, aluminum bags, aluminum foil bags, and aluminum foil boxes are very common packaging materials. Although, compared with a thin layer of plastic bags, kraft paper bags, transparent ziplock bags, etc., the cost of this layer of aluminum bags is not cheap. However, many merchants still choose to store tea in sealed aluminum bags. The starting point is that the light-proof and moisture-proof effect of this layer of aluminum bag is difficult to replace by other packaging. It's like going to the drugstore to buy medicine. Many medical drug packaging boxes are packaged in aluminum foil. What I like is that aluminum foil can protect against light and moisture at the same time!
Regarding the long-term storage of white tea, the three-layer packaging method is inseparable. Three layers of packaging, from outside to inside, are cartons, plastic bags, and aluminum bags. Through layer-by-layer sealing, the effect of sealed tea storage is achieved. However, there are many rumors in the tea circle surrounding this classic three-layer tea storage packaging. Or worse, stigmatize them. For example, as mentioned today, aluminum bags can contaminate tea. As I encountered earlier, some people said that you should not use plastic bags to store tea, otherwise it will taste like plastic. Also, some people slander that cartons are not moisture-proof and have a "carton smell". In fact, in the face of these rumors, tea drinkers must remain rational rather than blindly follow them.
