As the saying goes, food is the pri

As the saying goes, food is the primary necessity of the people. Therefore, since ancient times, we have been processing food, which is why the first packaging was born. For example, in nature, countless plants and fruits have packaging that can protect themselves. This form of natural packaging will also inspire future applications in life. The zongzi we eat is made from natural crops as packaging materials. Because lotus leaves are a fresh plant, they can play a role in cooling and maintaining freshness. They are an indispensable food for every family. Including the usage we often see in TV dramas, where the ancients used gourds to hold wine. Due to the hard shell of the gourd, it is easy to carry and has good anti-corrosion and moisture-proof functions, making it widely used by people. The characteristics of these packaging are still in use today and have been extended to many places of life. The lotus leaf steamed rice, wooden barrel rice, bamboo tube rice, pineapple rice, etc. we now eat all have the same purpose. The earliest ancient people utilized the unique nature of natural materials and used them reasonably in packaging, which reflects the crystallization of human wisdom and is highly worthy of our research.
