d. Recycled packaging design. Try to avoid using a variety of different materials in order to facilitate recycling and recycling of materials;
e. Reuse packaging design. A variety of packaging containers with good design quality and long service life;
f. Degradable material packaging design. Photodegradable plastics, biodegradable plastics, photo/biologically degradable plastics, chemically degradable materials, natural polymeric materials, edible packaging materials, etc.
Green packaging production process. In the packaging industry, the production process of packaging products will more or less appear "three wastes" substances, causing some pollution to the environment. How to control waste to a minimum requires the implementation of a cleaner production strategy. Cleaner production refers to the use of clean energy and raw materials, using clean production technology, and production of clean products. During the production process, advanced technologies and equipment that are pollution-free and less polluting are used to replace the backward processes and equipment that consume high amounts of pollutants, and large quantities of green materials that are non-toxic, low-toxicity, and less polluting, and energy are used instead of raw materials that are heavily polluted. Energy; strengthen enterprise management, reduce material loss and run, risk, drip, and leak of pollutants. Cleaner production is a new and creative way of thinking about the prevention of pollution in products and manufacturing processes, that is, the continuous use of overall prevention of environmental protection strategies for product production.
The UNEP UNEP concept for cleaner production is: for the production process - clean production includes saving raw materials and energy, eliminating toxic raw materials and reducing their quantity and toxicity before all emissions and wastes leave the production process; The Cleaner Production Strategy aims to reduce human and environmental pollution during the entire production cycle of the product. The goal of cleaner production is to save energy, reduce consumption, and reduce pollution, so as to achieve the unity of environmental and economic benefits. Therefore, the implementation of clean production of packaging can maximize social-environmental economic benefits.
Packaging waste recycling, utilization and disposal. The packaging waste disposal technology can be divided into: physical technology, chemical technology, biotechnology, heat treatment technology and curing technology. Recycling and recycling of packaging wastes:
Through green processing, the waste can be controlled and utilized to the maximum extent to realize waste reduction, reduction, minimization, and recycling.
2 The main content of the course setting
The author believes that the "Green Packaging" edited by Dai Hongmin, Wu Jun, "Green Packaging" written by Li Heping, "Recycling of Packaging Materials and Urban Environment" edited by Yang Fuxin, etc., and New Practical New Materials for Food Packaging, written by Weng Duan The "Environmental Materials Science" and Liu Guangfu's "Green Design and Green Manufacturing" and other books are very good. The book is rich in content, involves a large number of environmental protection packaging content, can be used as a course teaching material or reference materials for packaging environmental education .
3 Conclusion
In the face of the global green packaging revolution, China's packaging education should proceed from the perspective of protecting the environment, saving energy, and saving resources, implementing green packaging education, and taking the road of sustainable development. The implementation of green packaging education is an important guarantee for the sustainable development of the packaging industry. In the education of packaging disciplines, we must run through the idea of ​​green education—green packaging education, guide students to learn and understand how to adopt green packaging materials, implement green packaging design, green cleaner production technologies, and pay attention to and strengthen the use of packaging in future work. The management and management of materials, the establishment of packaging waste recycling systems, improve the recycling of waste packaging and comprehensive utilization of technology and continuous research and exploration of new technologies, new processes, the implementation of green packaging technology in order to better protect the environment for human survival.
