Green packaging content and classification

1.1 Connotation of Green Packaging Green packaging should generally have five aspects: First, reduce packaging. Packaging should meet the requirements of protection, convenience, sales, etc., and should be used in the minimum amount. The second is that the packaging should be easy to reuse or easy to recycle. Through the production of recycled products, incineration and utilization of heat energy, composting to improve soil and other measures to achieve the purpose of reuse. Third, packaging waste can be degraded (Degradable). In the end, it does not form permanent waste, so as to achieve the purpose of improving the soil. Reduce, Reuse, Recycle, and Degradable are the 3R1D principles recognized by the world today for the development of green packaging. Fourth, packaging materials should be non-toxic and harmless to humans and organisms. Packaging materials should not contain toxic elements, germs, heavy metals; or these contents should be controlled below relevant standards. Fifth, packaging products from the collection of raw materials, materials processing, manufacturing products, product use, waste recycling, until the final processing of the entire life of the process should not cause harm to the human body and the environment.

1.2 The origin of green packaging

The green packaging originated in the "Our Common Future" issued by the United Nations Environment and Development Committee in 1987. By June 1992, the United Nations Conference on Environment and Development adopted the Rio Declaration on Environment and Development and Agenda 21, and it was immediately In the world, a green wave centered on protecting the ecological environment has been set off. "Green Package" has been called "Environmental Friendly Package" or "Eological Package". Green packaging should be: no harm to the ecological environment and human health, recycling and reuse, can promote the sustainable development of the national economy packaging. In other words, the entire process of packaging products from raw material selection, product manufacturing, use, recycling and disposal should meet the requirements of ecological and environmental protection. It includes such contents as conservation of resources, energy, reduction, avoidance of waste generation, easy recycling, recycling, incineration or degradation, and other ecological and environmental protection requirements. The content of green packaging With the advancement of science and technology, the development of packaging will also have new connotations.

1.3 Grading of Green Packaging

Green packaging is divided into A grade and AA grade. Grade A green packaging refers to the appropriate packaging of wastes that can be recycled, reused or degraded, and contain toxic substances within the specified limits. Grade AA green packaging refers to waste that can be reused, reused or degraded, and does not cause harm to the human body and the environment throughout the product life cycle. Moderate packaging of toxic substances is within the specified limits. The above classification is mainly to consider the issue of waste after packaging is first used. This is pollution in the process of protecting the environment around the world. This is a problem that needs to be solved in the past, present, and future. The life cycle analysis method (LCA) is a method of evaluating the environmental performance of the packaging, and it is also a method to compare the environmental performance of the packaging materials. However, the problem should be prioritized.
