Fully biodegradable plastic bags, degradable plastic bags, and microbially degradable plastic bags: which is better?

From Since Sten Gustaf Thulin, a Swedish packaging designer, designed the plastic bag in 1959, plastic bags have been around for 61 years. Plastic bags have driven the development of human society. Now, the vast majority of things around us are plastic products. However, plastic bags have become the world's biggest environmental pollution problem. Numerous scientists from many countries and various packaging bag manufacturers are working to control this white pollution, protect the environment, and find alternatives to plastic bags to reduce environmental pollution. Later, many different degradable bags appeared online, including degradable plastic bags, microbial degradable bags, and fully biodegradable bags. So, what kind of degradable bag can truly contribute to environmental protection? Shunxingyuan Packaging, a professional flexible packaging manufacturer, will discuss the differences between these three types of bags, hoping to provide a reference for customers who need to customize degradable plastic bags.

Degradable plastic bags ： These are plastic bags mainly made of polyethylene, mixed with photodegradable agents and mineral powders such as calcium carbonate. They are also called photodegradable plastic bags. These bags decompose under sunlight. However, the polyethylene after decomposition still exists in the natural environment. Although white pollution is not visible, it still harms the surrounding environment in the form of fine particles.

Microbial degradable plastic bags: These are plastic bags mainly made of polyethylene, mixed with biodegradable agents such as starch. They are also called biodegradable plastic bags. These bags mainly decompose through microbial action, and the effect is the same as photodegradable plastic bags—treating the symptoms, not the cause.

Fully biodegradable plastic bags: These are made mainly of polylactic acid, which is fermented from corn. After degradation, they completely turn into carbon dioxide and water, a fully biodegradable material. They are a true degradable bag and can be considered an alternative to plastic, fundamentally solving the problem of plastic pollution instead of just treating the symptoms.

Fully Biodegradable plastic bags have advantages over traditional plastic bags in terms of performance, practicality, degradability, and safety.

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

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

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

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