Process packaging, green

The Chinese nation is one of the world’s greatest, oldest, and longest cultural and historical peoples and has made countless outstanding contributions to the development of science and culture in human society. In the four major inventions of ancient China, "papermaking" and "printing" were two major inventions directly related to packaging. A large amount of historical facts and unearthed cultural relics prove that the Chinese nation is one of the earliest peoples in the world who invented and used packaging.

The earliest packaging can be traced back to the primitive era. As early as 8000 years ago, our ancestors could use fired ceramic items. Plant leaves, shells, gourds, bamboo tubes, animal shells, animal skins, etc. are loaded into the annals of human civilization as the packaging of objects. From Zhang Qiang to the Western Regions to Zheng He's western voyage, packaging can create conditions for the preservation of objects, long-distance transportation and exchange. “Han Feizi’s Foreign Reserve Theory” chronicles the story of “Buying and Returning the Pearl”. A merchant from Chu State made a beautiful box out of precious wood, placed the big pearl in the box, and got Zheng Guo to sell. A Zheng Guoren was attracted by the magnificent, fragrant box and bought it at a high price, but returned the pearl to the businessman. This story is intended to ironic that Zheng Guoren did not know the elegance of jewelry, but it also shows that ancient businessmen have realized the importance of product packaging.

The variety, variety, and style of modern goods make them more demanding for packaging. Commodity packaging is the continuation of the production of goods. Only through packaging, can we count the completion of the production process, and commodities can enter the circulation and consumption fields before they can realize the use value and value of the goods. This is because packaging is an important measure to protect the integrity and quantity of goods in the circulation process. Some commodities may not even leave packaging at all, and it becomes an inseparable unified whole with the packaging. In the current fierce competition in the international market, many countries regard improving packaging as an important means of strengthening external sales. Good packaging can not only protect the goods, but also promote and beautify the goods, increase the value of the goods, attract customers, and expand sales. , increase the selling price, and to some extent show the country's science, culture, art level.

The spring breeze of reform and opening up led to the rise and development of the packaging industry and the packaging industry, including packaging education. Before that, China had almost no packaging industry, let alone package education. In 1980, the China Packaging Technology Association was established. In 1982, the China Association of Packaging and Packaging Educational Committee was established. Then the Ministry of Education incorporated the packaging engineering specialty into the undergraduate professional pilot program in 1984. During the major professional catalog adjustments in 1992 and 1997, not only Retained, and removed the trial hat, included in the national undergraduate directory of higher education, and thus ended the history of China without packaging engineering higher education. At present, about 2,000 graduates can be trained each year in the country. Not only do they work in packaging enterprises, but also in other industries, where there are companies that produce and circulate products, due to fierce market competition and export development, the packaging process is becoming more and more important. There is also an urgent need for packaging specialized personnel. It is based on this demand that Beijing Forestry University opened its packaging engineering program in 2002.

The specialty of packaging engineering has comprehensive characteristics, which makes it impossible for any college or university to turn packaging engineering into full-fledged majors of various subjects. It must be based on the original disciplines and highlight its own characteristics. The School of Materials Science and Engineering has experts and talents in the fields of materials and design. Combining with the discipline foundation, the packaging engineering specialty forms a combination of packaging materials, technology, and packaging system design. In today's society, the green wave is booming all over the world, and green has become a color representing the environment, representing the forest, and symbolizing life. Green packaging is a kind of green industry and it is the general trend of the world packaging industry to adapt to the development of the world environmental protection trend. As a packaging engineering major in forestry universities, we are more focused on implementing green education that protects the environment and sustainable development.

In the past 20 years, although China's packaging industry has made great achievements, as an emerging industry, its growth and development are still immature, and there is still a big gap compared with developed countries. Judging from the total amount, China has gradually become a big packaging country, but it is not a packaging power. To achieve the goal of becoming a strong nation, we need more fresh blood to supplement our country's packaging industry, so that our country can enter the world's packaging power as quickly as possible. forest.
