Briefly explain the impact of pe bags on the environment

It takes about two hundred years for pe bags to be buried in the ground before they decay and will severely pollute the soil; if the combustion method is adopted, harmful smoke and toxic gases will be produced, which will pollute the environment for a long time.　　Degradable plastics are difficult to degrade. The common 'degradable plastic bags' on the market actually only add starch to the plastic raw materials. After the landfill, due to the fermentation of starch and the differentiation of bacteria, large plastic bags will be broken into small pieces that are even invisible to the naked eye. This is a physical degradation and does not fundamentally change the chemical properties of plastic products.　　 affects the normal respiration of the soil. The plastic bag itself is not one of the fundamental substances of soil and water body. After being forced into the soil, due to its own air impermeability, it will affect the heat transfer inside the soil and the growth of microorganisms, thereby changing the characteristics of the soil. The accumulation of these plastic bags over a long period of time will also affect the absorption of nutrients and water by crops, resulting in reduced crop yields.　　 is easy to be eaten by animals. Plastic bags discarded on the ground and on the water are simply swallowed by animals as food. Plastic bags cannot be digested in the animal’s intestines and stomach, which can easily lead to animal body damage and death. Tag: pe waterproof bag
