Nowadays, the voice of protecting the environment, reducing pollution and saving costs in the world is getting higher and higher, and the international market is increasingly regulating the packaging materials. Environmentally friendly packaging materials that are pollution-free, non-polluting and recyclable play a major role in the export trade of products.
Environmentally friendly packaging materials generally include: recyclable and renewable packaging materials, edible packaging materials, degradable materials and natural paper materials.
The advantages of environmentally friendly packaging materials are reflected in the use of materials, pollution, pollution, recycling and reuse, without secondary pollution. Therefore, the selection of environmentally friendly packaging materials should be consistent with the basic principles of pollution-free, non-polluting and recyclable. Pure natural environmental packaging materials, although non-polluting, have high commercial costs and are a waste to the earth's capital. Composite environmentally friendly materials will become the mainstream trend of environmentally friendly packaging materials because of their low cost, no pollution, and easy recycling. .
Green materials are now divided into three main types:
1, completely non-toxic and harmless
It refers to pure natural materials that have no or little toxic substances, no pollution, and only rough processing materials. Such as gypsum, talcum powder, wood and some natural stone.
2, low toxicity and low emission type
It refers to the processing and synthesis of technical means to control the accumulation and release of toxic and hazardous substances. Because of its toxic nature, it is an environmentally friendly packaging material that does not pose a threat to human health, such as fiberboard with a formaldehyde content that meets national standards.
The current scientific and technological means cannot accurately judge and evaluate the impact of environmentally-friendly packaging materials. Just like environmentally friendly latex paints, environmentally friendly paints and other chemically synthesized packaging materials. These materials now appear to be non-toxic and harmless, but as science and technology improve, there may be new discoveries in the future.
Most of the environmentally-friendly packaging materials choose fully automatic intelligent equipment, digital packaging equipment, and high-performance packaging equipment such as energy-saving and comprehensive utilization equipment have been widely used. In addition, the recycling equipment for waste materials and secondary processing equipment are also in line with the requirements of environmentally friendly recycling.
