The raw materials of plastic bags are polymer compounds, which have stable structure and are not easily degraded by natural microorganisms. Non-degradable plastic bags need more than 200 years to rot naturally. If the waste plastic bags are not recycled, they will be mixed in the land, which will cause soil hardening, affect the absorption of nutrients and water by crops, and lead to crop yield reduction. Waste plastic bags discarded on land and in water will be swallowed by animals and fish as food, causing the death of animals and fish or affecting their growth.
Precautions in the use of plastic bags
Try to pack cooked food in plastic bags as little as possible. After packaging cooked food in plastic bags, it often causes food deterioration, and after eating, it is prone to food poisoning symptoms such as vomiting and diarrhea. In addition, the plastic bag itself will also release harmful extracts, which will accumulate in a sealed environment for a long time, and the concentration will increase with the increase of time, thus polluting the food in the bag and affecting human health, especially the healthy development of children.
Do not use ultra-thin plastic bags. Ultra-thin plastic bags are light in weight and thin in thickness, but they have strong load-bearing capacity, because plastic bag manufacturers add plasticizers in the production process, which is extremely harmful to human health, and national laws and regulations also prohibit manufacturers from producing and selling ultra-thin plastic bags.
