　　The development of packaging bags has gone through four distinct stages: the original packaging bag stage, the large packaging bag stage, the small packaging bag stage, and now it has gradually entered a new stage of environmental protection (green) packaging bags. With the development of commodity economy, the commodity nature of packaging itself is becoming more and more significant. It has become a special product that no longer depends on commodity production, a product that all commodities can not do without and is widely used.

　　Chinese scientists have developed an environment-friendly plastic bag made of electrolyte. This environment-friendly plastic bag can not only be decomposed harmlessly, but also be soluble in water.

　　According to scientists, products made of common polymer plastic materials in life will take hundreds of years to be completely decomposed and will exist on the earth for hundreds of years. According to the actual figures, 80% of the used plastic bags, most of which are finally transported to the garbage dump area for treatment like ordinary garbage, and only 7% of the plastic is recycled.

　　This new environment-friendly plastic bag will not release harmful substances in the decomposition process, and it can even be decomposed into natural substances favored by insects, which has played a great role in protecting the natural environment.
