With the international protection of the environment, care for the earth, saving resources increasingly high, the international market for product packaging requirements are more and more strict.  Harmless, pollution-free and renewable packaging plays an important role in commodity export trade.  The identification of environmental protection packaging is based on ISO14000, which is used as a standard to promote environmental protection packaging model.  Iso14000 series clearly stipulates that all international trade products (packaging) should be environmental certification and ecological assessment (LCA), and the use of environmental marks.  Since 1999, ISO has implemented a green “environmental mark”, pushing the green revolution in product packaging to a new level, which has a great promotion effect on Chinese exporters.

Environmental protection packaging materials generally include reusable and renewable packaging materials, edible packaging materials, degradable materials and natural paper materials, etc.  Environmental protection packaging is reflected in the use of materials, the least waste and energy saving, easy to recycle and reuse, packaging waste does not produce secondary pollution.  Therefore, the selection of environmental protection packaging materials should conform to the basic principles of harmless, pollution-free and renewable.  Pure natural environmental protection packaging materials although pollution-free, but the commercial cost is high, it is also a serious waste of earth resources.  Composite environment-friendly materials will become the mainstream of environment-friendly packaging in the future because of their characteristics of low cost, no pollution and easy recycling.

As the Eu, the US, Canada and other countries restrict the use of wood packaging for Chinese exports to enter the market, the development of substitute wood packaging materials is becoming more and more urgent, which also promotes the research, development and production of substitute wood packaging materials in China’s packaging industry.

The relationship between packaging and environmental protection has received great attention in developed countries. They not only have the support of laws and regulations, but also have the support of economic strength and humanistic concepts and other factors
