And easy to degradation of environmentally friendly plastic bags, while the cost is higher a little, but after abandoned, it can under the action of biological environment, can decompose, belongs to the green packaging. To sum up, the advantages of plastic than paper bags are obvious, but in the use of plastic bags, to increase the repeat utilization, reduce environmental pollution.
