Regular plastic bags and compostable plastic bags are two different types of bags with distinct characteristics and environmental impact. This article expands on the differences between regular and compostable plastic bags，what kind of plastic bags you usually use?

Material difference

Regular plastic bags are typically made from petroleum-based plastics, such as polyethylene (PE) or polypropylene (PP). These materials are non-biodegradable and can persist in the environment for hundreds of years, contributing to pollution and litter. In contrast, compostable plastic bags are made from renewable resources, such as plant-based materials like cornstarch or sugarcane. These bags are designed to break down into natural elements under specific composting conditions.

Degradation process difference

Regular plastic bags do not naturally biodegrade in the environment. Instead, they fragment into smaller pieces known as microplastics, which pose a significant threat to ecosystems and wildlife. On the other hand, compostable plastic bags undergo degradation through a composting process, where they break down into water, carbon dioxide, and organic matter (compost) within a specific time frame, usually around 90-180 days.

For Environmental difference

Regular plastic bags contribute to various environmental problems. They require significant amounts of energy and resources to produce, and their improper disposal leads to litter, clogged drainage systems, and harm to wildlife. Additionally, regular plastic bags can take hundreds of years to decompose, causing long-term pollution. Compostable plastic bags, when properly composted under controlled conditions, have a reduced environmental impact. They can contribute to compost production, enriching the soil and supporting plant growth.

In addition to the above points, there are many benefits of compostable plastic bags, such as:

·  Compostable plastic bags can be integrated into the organic waste process and composted with other organic waste. Through the rational use of organic waste resources, organic fertilizers can be produced for use in agriculture and horticulture, and promote the development of a circular economy.

·  Compostable plastic bags can be used as a more sustainable alternative to traditional non-degradable plastic bags. They are similar to conventional plastic bags in some functions, but have better environmental impact, and can be quickly decomposed under appropriate conditions, reducing the burden on the natural environment.

Conclusion

It can be seen that compared with ordinary plastic bags, compostable plastic bags are safer and more secure in terms of material composition, and the degradation process is more environmentally friendly. Therefore, for our long-term living environment, it is strongly recommended that you use this compostable plastic bag. What do you think about this?
