Chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering". Any technology that uses chemical methods to change the composition and structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process. The products obtained are called chemicals or chemical products. At first, the production of this kind of products is manual workshops, and later evolved into factories, and gradually formed a specific production industry, namely the chemical industry. Chemical engineering is a science to study the common law of chemical product production process. The relationship between human and chemical industry is very close. Some chemical products play an epoch-making role in the history of human development. Their production and application even represent a certain historical stage of human civilization.
With the enhancement of environmental protection consciousness, the key problems of "green" packaging design for industrial products are urgently to be solved. This paper analyzes how to reduce environmental pollution as much as possible and achieve higher recovery rate in product packaging, and makes in-depth discussion and Research on the selection of packaging materials and design methods.
Bag packaging is an ideal packaging container for chemical fertilizer, pesticide, cement, grain and other powder and granular products, which generally ranges from 20kg to 50kg. It is easy to load, unload, stack, transport and store.
