What is the structure of traditional Chinese medicine paper packaging?

In the early years, Chinese medicine used unbleached reed paper, which was divided into two layers. One piece of paper inside is smaller, and the other piece of paper outside is bigger. After wrapping, tie the prescription and paper bag together with a paper rope, leaving a "hook" for walking.

After liberation, there appeared a "kraft paper bag" filled with traditional Chinese medicine, which was nailed with a stapler instead of tied with a paper rope and packed in a bag to take away, which was very convenient.
