Comparative analysis of different degradable plastic bag materials and their application fields

Since 2020, the biodegradable plastic bag industry has received significant market attention, thanks to the release of policies such as "Further Strengthening the Governance of Plastic Pollution" and "Notice on Solidly Advancing the Governance of Plastic Pollution."

　In terms of materials, biodegradable plastic bags are mainly made of PLA, PBS, PBAT, and other polyester-based biodegradable plastics and starch-based plastics. Although starch-based plastics are relatively inexpensive and completely biodegradable, their short lifespan and poor mechanical properties limit their applications.

Currently, the most widely used and largest-produced biodegradable plastics are PLA and PBAT. PLA can be used in disposable lunch boxes in the food packaging industry, food and beverage outer packaging, and high-value-added films, as well as in the biomedical field. PLA is also used in medical sutures, drug controlled-release carriers, orthopedic internal fixation materials, engineering scaffolds, drug sustained-release control materials, and ophthalmic materials. PBAT is used in disposable plastic bags and disposable tableware in the food packaging industry, and in the agricultural field, it is used in plastic packaging films, agricultural films, and disposable plastic bags.

Using biodegradable plastic bags offers advantages over traditional plastic bags in terms of performance, practicality, biodegradability, and safety.

In terms of performance, biodegradable plastic bags can achieve or even surpass the performance of traditional plastic bags in certain specific areas.

In terms of practicality, biodegradable plastic bags have similar application and hygiene performance to their traditional counterparts.

In terms of biodegradability, after use, biodegradable plastic bags can degrade relatively quickly in natural environments (specific microorganisms, temperature, and humidity), becoming easily utilized fragments or non-toxic gases, thus reducing environmental impact.

In terms of safety, the substances produced or remaining during the degradation of biodegradable plastic bags are harmless to the environment and do not affect the survival of humans and other organisms.
