For the storage of degradable garbage bags, the shelf life of degradable plastic bags is only about three months. Even if they are not used, they will naturally degrade within five months. In the sixth month, plastic bags will be covered with “snowflakes” and cannot be used. Under composting conditions, even the newly produced degradable plastic bags can be completely degraded in only three months.
The biodegradable garbage is marked with a unified Chinese environmental label on the biodegradable plastic bag, which is a green mark composed of Qingshan, Green Water, Sun and ten rings. If it is a plastic bag for food, it must also be printed with a food safety permit qs Mark and mark “food use”.
Why use degradable garbage bags? Biodegradable plastic bags and plastic tableware are new types of biodegradable materials. Ordinary plastic bags and plastic tableware are involved in the problem of “white pollution”. They do not decompose underground and are harmful to crops, water sources, animal husbandry, and humans themselves. After the degradable plastic products are buried in the soil, because the surrounding environment can meet the decomposition requirements, they will be completely decomposed into carbon dioxide and water, which belongs to the organic cycle and is harmless to the human body and the environment.
