Brief Discussion on Green Packaging (I)

The revolution in science and technology not only brought about rapid development for social productivity, but also created tremendous material wealth for mankind. At the same time, it also created unprecedented destructive power and caused serious pollution to the ecological environment. The packaging industry is one of the important industries that cause pollution. To solve the pollution problem in the packaging industry, a “green revolution” is emerging in the packaging industry.
The rise of green packaging originated from the proliferation of white pollution. The root cause lies in the increasing packaging waste that comes with the increasing availability of packaging materials and packaging products. Because people ignore the environmental factors in the production and management activities, they ignore the intractable plastic packaging products, and do not recycle the recycled packaging products, causing serious environmental pollution.
"Green revolution" is a major change in the world packaging industry, and it is also a major trend in the development of the packaging industry in the new century. It has become an irreversible trend in commodity production and world trade. This kind of change is the inevitable result of adapting to environmental protection and saving resources in all aspects of concepts, materials, production, and consumption. The main contents of the “green revolution” in the packaging industry include: reducing unnecessary waste, providing renewable products, paying attention to economic benefits and ecological benefits, and not using products that pollute the environment and destroy nature.
About the definition of green packaging and grading objectives The green packaging has the following four aspects: The material is the most provincial, the least waste, and saves resources and energy; easy to recycle and recycling; waste combustion produces new energy without producing Secondary pollution; minimum packaging material and self-decomposition, no pollution to the environment. Based on this, we can give the following definitions for green packaging; we can call it green packaging, which can recycle, re-use or degrade, and appropriate packaging that does not cause harm to the human body and the environment throughout the product's life cycle. .
Green packaging is ideal packaging, and it takes a process to fully meet its requirements. In order to achieve both the direction of the pursuit and the goals that can be achieved in stages, we can formulate green grading grading standards according to the green food grading standards.
Grade A green packaging: refers to waste that can be reused, reused or degraded, and contain toxic substances within the specified limits.
AA grade green packaging: refers to the waste can be recycled, reused or degraded, and does not cause harm to the human body and the environment during the entire product cycle. The toxic substance content is moderately packaged within the specified limits.
The main considerations of the above classification are the waste problems after packaging and use. This is a hot spot for the protection of the environment in the world and is also the main content of the development of green packaging. On this basis, the pollution in the packaging production process is a Efforts have been made for many years, but problems still need to be resolved.
The design of green packaging and the classification of materials Green packaging products are also known as environmental friend packaging or ecological packaging, and are harmless to the ecological environment and human health. The packaging products must be selected from raw materials, manufacturing, use, recycling and disposal of products. The process is comprehensively measured so that it meets the requirements of ecological environmental protection and can maintain a virtuous circle in the natural ecosystem. According to this principle, some professionals put forward six aspects of the design of green packaging: (to be continued)
