Green and environment-friendly packaging is the only way for China's packaging industry

Environmentally friendly packaging
With the international voice of protecting the environment, caring for the earth and saving resources getting higher and higher, the international market has increasingly strict requirements on product packaging. Environmentally friendly packaging, which is harmless and renewable, plays an important role in commodity export trade. The basis for identifying environmental protection packaging is iso14000, which is the standard for all countries to promote environmental protection packaging mode. Iso14000 series expressly stipulates that all international trade products (packaging) should be subject to environmental certification and ecological assessment (lca), and use environmental labels. Since 1999, iso has implemented green "environmental labeling", pushing the green revolution of product packaging to a new level, which has greatly promoted chinese exporters. Therefore, relevant experts suggest that export enterprises should start from the following aspects when implementing environmental protection packaging:
packaging
Environmental protection packaging materials generally include reusable and renewable packaging materials, edible packaging materials, degradable materials and natural paper materials. Environmental protection packaging is characterized by material saving, less waste and energy saving, easy recycling, and no secondary pollution from packaging waste. Therefore, the selection of environment-friendly packaging materials should conform to the basic principles of harmless and renewable utilization. Although environmental protection packaging materials are non-toxic, their commercial costs are high and they are also a serious waste of earth resources. Composite environmental protection materials will become the mainstream of environmental protection packaging in the future due to their low cost, easy recycling and other characteristics.
Packaging shall be easy to reuse or recycle. This is a practical step to develop green packaging materials at this stage, and an active waste recovery and treatment method. At present, polyester beverage bottles, milk bottles and glass beer bottles can be reused for many times. Those that cannot be reused should be differentiated as much as possible and ablated from scratch.
In order to reduce the damage of packaging waste to the environment, China put forward the concept of "green packaging" 10 years ago. There are two meanings of green packaging: overall environmental protection and capital regeneration
Packaging reduction. That is, under the condition of satisfactory maintenance, convenience, sales and other functions, the amount of packaging should be reduced as much as possible.
Packaging wastes can degrade and decay, and do not constitute permanent wastes. Degradable plastics are being studied all over the world to solve the severe environmental problems caused by the current non degradable plastics. The principle of degradation is to separate, degrade and restore plastics in the natural environment through the effect of microorganisms in soil and water or the effect of ultraviolet light in sunlight, and enter the ecological environment from scratch in a non-toxic way, returning to nature.
Packaging materials shall be harmless and non-toxic to human body and biology. Packaging materials should not be rich in toxic elements, heavy metals, or the rich content should be controlled below the relevant specifications.The whole process of packaging products from raw material collection, processing, commodity production, commodity use, waste recovery to disposal should not cause public hazards to human body and the environment.
