Chemical

Chemical Engineering is an abbreviation for "Chemical Process", "Chemical Industry", "Chemical Engineering", etc. Any technology that uses chemical methods to change the composition, structure or synthesis of new substances belongs to chemical production technology, that is, chemical processes, and the resulting products are called chemicals or chemical products. At first, the production of such products is a manual workshop, and later evolved into a factory, and gradually formed a specific production industry, namely the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. 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 awareness, the key problems to be solved in the "green" packaging design of industrial products. Specifically analyzed how to make the product packaging as much as possible to reduce the ring pollution, to achieve a higher recovery rate, and the selection of packaging materials and design methods in-depth discussion and research.

bag packaging is an ideal packaging container for powder and granular products such as chemical fertilizers, pesticides, cement, grain, etc. The range is generally 20kg-50kg, which has the characteristics of easy loading and unloading, palletizing, transportation and storage.
