Can biodegradable film bags be used as a substitute for traditional plastic bags?

Biodegradable film bags can serve as alternatives to traditional plastic bags.
Traditional plastic bags are mainly made of chemical materials such as polyethylene, which degrade very slowly in the natural environment and even take hundreds of years, leading to serious "white pollution" problems. Moreover, traditional plastic bags may produce harmful substances during production and use, posing a potential threat to the environment and human health.
In contrast, biodegradable film bags are made from bio based materials, which can be decomposed into low molecular weight compounds by microorganisms such as bacteria, molds, and algae that exist in nature under certain conditions, and ultimately converted into water and carbon dioxide, which are absorbed by soil and plants, achieving harmless degradation. Therefore, biodegradable film bags have advantages such as green environmental protection, energy conservation and emission reduction, and renewable raw materials.
In addition, to assist in garbage classification work, newly developed biodegradable plastic bags are usually divided into different colors, matched with the color of the classified garbage bin, and equipped with classification labels and instructions, making it convenient for people to distinguish different types of garbage in their daily lives.
However, despite the many advantages of biodegradable film bags, their production costs are usually higher than traditional plastic bags, which is the main obstacle to their popularization. But with the improvement of environmental awareness and the continuous development of technology, this problem is expected to be solved.
Therefore, from the perspective of environmental protection and sustainable development, biodegradable film bags have the potential to become alternatives to traditional plastic bags.
