Why is it the trend for health products to be packaged in iron boxes

The market of health products is so large that the iron box health food packaging is just the tip of the iceberg in the market. Low grade ginseng, American ginseng, ass hide glue, loquat paste and cough medicine health products are often used.
However, we can see from the tinplate packaging used abroad that the proportion of tinplate packaging in foreign countries is very high. Many Christmas gift boxes, holiday gifts, party gifts, health food, and health pharmaceutical product boxes are imported from China. After 2001, the domestic economy grew rapidly, and the consumption of food and health products increased sharply. Packaging also received a huge impact. Tinplate is an environmentally friendly material that can be recycled and reused. The conclusion of the 2010 Shanghai World Expo has shown that domestic enterprises in China have placed a high priority on environmental protection. In one aspect, health products are also a manifestation of the demand for better quality living water products.
