What kind of material is better for making tea cans?

The Packaging Gift Box design industry is becoming increasingly popular, and I personally believe that the materials used in the design are also different for different products. What kind of material is better for making tea cans?
Paper boxes are prone to moisture and can easily spoil tea leaves, while iron and porcelain jars have strong sealing and aesthetics, making them generally better for storing green tea. Due to its strong antioxidant capacity, good airtightness, low oxygen permeability, good conductivity, and absence of metal odors, Iron Cans are the container of choice for storing tea and are commonly used for storing tea, food, and other items. Iron Boxes are widely used for Food Packaging both domestically and internationally. They are a good material for food preservation and packaging, with the functions of airtight preservation, oxidation resistance, light blocking, and no odor generation. So in terms of practicality, using Tin Cans (tin cans) to store tea is relatively good, which can better protect the tea.
