THE DEVELOPMENT OF PACKAGING-1

Like the history of human development, packaging has also experienced a long development process. Starting from the function that is convenient for carrying at the beginning, it has gradually evolved into modern packaging that integrates display, carrying, and publicity. It has undergone a long evolution.

From a large perspective, all things used to wrap items can be called packaging. From a small perspective, the packaging of commodities used for circulation is called packaging. In the five thousand years of changes in China, what changes have packaging experienced? let us clear the fog of history and explore the truth step by step.

In primitive society, because people's mastery of production skills is extremely low, all packaging comes from natural rough processing. The rattan and leaves of nature, the gourd scoop processed for the convenience of water intake, in short, the packaging at this stage is mainly formed naturally and can be said to be the packaging from nature.

Because this kind of packaging is simple and easy to obtain materials, there are still many places where it has been applied until now, such as the zongzi we eat at the Dragon Boat Festival, and the outer zongzi is the embodiment of this packaging in modern society.

In the late Neolithic Age, due to the great development of human productivity, the art of making pottery made of soil appeared during this period. This simple and easy-to-manufacture method turned the original mode of relying on nature into a self-sufficient one. Packaging was greatly developed, and at the same time, due to the initial discovery of dyes, there were initial aesthetic designs on this pottery. The representative of this period is the packaging of various ropes that are refined with thatch vines as raw materials, and the clay pots are processed with soil as raw materials.

In the late neolithic, due to the emergence of the social division of labor, the development of metallurgical technology and the emergence of businessmen, and bronze on the stage, the most representative of this age is the pot of meat and drinking of wine, at the same time due to the emergence of the businessman, then appeared in the true sense of the packaging.

During the Eastern Han Dynasty, Cai Lun invented papermaking, which made paper, brilliant packaging material in later generations, appear in front of the world for the first time, paper board has almost taken over most of the packaging industry. At that time, paper was mainly used as a convenient material, such as paper for medicine, and paper for wrapping meat (now we use food-grade kraft paper), which we can often see in TV dramas. Coupled with the maturity of iron smelting technology, a variety of nature-based packaging has emerged. Processing packaging, such as various baskets produced with bamboo, due to the certain skill of this packaging, certain occupational models have appeared. The ancestors of bamboo craftsmen, bamboo craftsmen, etc. It appeared in the period, and it also contained a lot of paper packaging.

Since China began to raise silkworms and make silk a long time ago, before paper making, silk was generally used as a packaging material popular among the ancient nobility. At the same time, due to the rarity, some valuable jewelry and jade began to become the favorite among the nobility. So until modern times, although the price of silk and satin has been very low, in the packaging industry, it is still a symbol of high-end.

Later, due to social productivity, products are in short supply, all the packaging is actually the goods to hold things, and there is no modernization mark in a strict sense.

Until the British industrial revolution, machines to replace people have become the main force of production, and the product is in great abundance, so the packaging first boarded the stage of history, as propaganda and technology constantly change, printing technology leaped, and the packing finally gets rid of the subordinate status of the past, turn to do the master, formally entered the stage of modern society (Printing paper began to combine with other instruments). However, due to the closed-door policy of feudal society, Packaging did not develop in China until the Period of the Republic of China, falling far behind foreign countries. However, after so many years of development, the packaging industry has made great progress and formed its own unique culture from design to production.

After the invention of plastic packaging, plastic material really opened up a new field that paper could not win. However, environmental pollution caused by waste materials such as polyvinyl chloride, foaming polypropylene, and aluminum foil used as food and beverage packaging materials, may gradually evolve into ethyl chloride monomer, which is likely to cause cancer in the human body, or it may give off a strange smell. In particular, when polyvinyl chloride is used for combustion, it will release extremely harmful gas bodies, resulting in large gas pollution. Therefore, Time calls for the paper wrap return.
