What is green packaging and how will society develop green packaging in the future

by admin

also known as pollution-free packaging and friendly package, refers to packaging that is harmless to the ecological environment and human health, can be reused and regenerated, and is in line with sustainable development. Its concept has two meanings:
one is to protect the environment, the other is to save resources. The two complement each other and are inseparable. Among them, protecting the environment is the core, and saving resources is closely related to protecting the environment, because saving resources can reduce waste, which is actually the protection of the environment from the source

from a technical point of view, green packaging refers to an environment-friendly packaging developed with natural plants and related minerals as raw materials, which is harmless to the ecological environment and human health, conducive to recycling, easy degradation and sustainable development. In other words, the whole life cycle of its packaging products from raw material selection, product manufacturing to use and waste should meet the requirements of ecological and environmental protection Packaging design and vigorously develop green packaging industry to realize green packaging

specifically, green packaging should have the following meanings:

1) implement packaging reduction (rece). Under the condition of meeting the functions of protection, convenience and sales, green packaging should be the appropriate packaging with the least consumption. Europe and the United States and other countries have listed the reduction of packaging as the first choice for the development of harmless packaging

2) the packaging should be easy to reuse or recycle. The purpose of reuse can be achieved through repeated reuse, or by recycling waste, producing recycled products, burning and utilizing heat energy, composting and improving soil. It not only does not pollute the environment, but also makes full use of resources

3) packaging waste can degrade (). In order not to form permanent
waste, the non recyclable packaging waste should be able to decompose and decay, so as to improve the soil. Industrial countries all over the world attach importance to the development of biodegradable or photodegradable packaging materials. Rece,
reuse, recycle and are the 3R and 1D principles for developing green packaging recognized by the world in the 21st century

4) packaging materials shall be non-toxic and harmless to human body and organisms. The packaging materials shall not contain toxic substances or the content of toxic substances shall be controlled below the relevant standards

5) in the whole life cycle of packaging products, there should be no pollution or public hazard to the environment. That is, the whole life process of packaging products from raw material collection, material processing, product manufacturing, product use, waste recycling to final treatment should not cause public hazards to human body and environment

in the above meaning of green packaging, the first four points should be the requirements that green packaging must have, and the last point is the ideal and highest requirements for green packaging from the perspective of system engineering based on life cycle assessment. From the above analysis, green packaging can be defined as: green packaging is an appropriate packaging that can be recycled, recycled or degraded, and does not cause public hazards to human body and environment in the whole life cycle of products.
