Traditional Plastic Bags Have Gradually Been Replaced By Biodegradable Plastic Bags

Plastic pollution is a major global challenge, silently threatening the health of life on Earth. In March 2022, the resolution to end plastic pollution was passed at the resumed fifth session of the United Nations Environment Conference. The resolution established an intergovernmental negotiation mechanism and reached an internationally legally binding agreement by 2024, covering the production, design, recycling, and treatment of plastics and their products. Ending plastic pollution requires joint efforts from all countries to manage the lifecycle of plastic products sustainably. Plastics can cause environmental damage at various stages of their lifecycle: Traditional petroleum-based plastics produce various organic pollutants, including toluene, xylene, and ethylbenzene, during the production stage. These pollutants eventually enter the atmosphere and water sources, becoming greenhouse gases that cause global climate change. After use, discarded plastic will enter the soil, water sources, and oceans, affecting various organisms and humans through the food chain. In 2021, microplastic particles first appeared in the placenta. It can be seen that the impact of plastics on human health has become extremely serious. The short degradation time of biodegradable plastics is an important solution to address "white pollution". Biodegradable plastics refer to plastics that meet the performance requirements of their products, maintain their performance during the storage period, and can degrade into environmentally friendly substances under natural environmental conditions after use. They can be transformed into fertilizers, carbon dioxide, and water through composting treatment. After planting crops containing sugar or starch, they can be further transformed into organic molecules for the production of polymer materials through fermentation or chemical processing. This biodegradable cycle can significantly reduce the impact of waste plastics on the environment and is also an effective way to achieve resource recycling and utilization. Compared with traditional plastics, biodegradable plastics can be degraded by microorganisms in nature in a relatively short period under certain conditions, while traditional plastics require centuries of degradation and the resulting substances can cause significant environmental pollution. Biodegradable plastics are expected to significantly replace traditional plastics.

The field of Biodegradable shopping bags

Supermarket shopping bags are the most frequently used scenario for plastic bags. At present, the main substitutes for disposable non degradable plastic bags are paper bags and degradable plastic bags. Although paper bags have lower costs than degradable plastic bags, their strength is significantly weaker than that of degradable plastic bags, making them unsuitable for large shopping places. With the deepening of the plastic ban, the replacement of disposable nondegradable plastics with degradable plastic bags will gradually accelerate.

The benefits of biodegradable shopping bags:

1. Environmental protection: Biodegradable shopping bags are made of biodegradable materials. When discarded in the natural environment, the bags will be decomposed by bacteria, fungi, microorganisms, etc., and will not cause pollution to the environment.

2. Resource conservation: Most of the raw materials used in biodegradable shopping bags are renewable resources, such as starch and corn starch, which directly affect the implementation of sustainable development.

3. Safety and Health: Biodegradable shopping bags will not cause long-term harm to human health and the environment like traditional plastic bags, making them safer and more hygienic to use.

The field of biodegradable mailer bags

A degradation mailer bag is an environmentally friendly mailer bag, which has the characteristics of environmentally friendly material, fast decomposition speed, and convenient use. The use of biodegradable mailer bags can effectively reduce the environmental pollution caused by plastic bags, save costs, and enhance brand image. With the continuous improvement of environmental awareness, the application scope of degradable mailer bags will further expand, and it will become a new trend in the mailer delivery industry.

Degradable mailer bags have been increasingly adopted by courier companies around the world and have become the main type of mailer bag in some large courier companies. In the future, with the continuous improvement of environmental awareness, the application scope of degradable mailer bags will further expand.

The field of Agricultural Mulch Film

Biodegradable plastic film is mainly composed of materials that can be completely degraded by microorganisms in the natural environment and are made by blow molding with environmentally friendly additives that are harmless to the environment. In agricultural production, it not only has the functions of traditional PE film for moisture retention, warming, and weed control but also does not require manual recycling after use. It can be directly plowed into the soil and can be degraded in the soil, which can be described as efficient and environmentally friendly.

Biodegradable plastic film is achieved through the combined action of water, light, heat, and microorganisms in nature. The principle is that when microorganisms such as bacteria, fungi, and actinomycetes erode plastic films, the growth of cells causes hydrolysis, ionization, or protonation of polymer components, resulting in mechanical damage and splitting into oligomeric fragments. Enzymes secreted by fungi or bacteria can decompose or oxidize water-soluble polymers into water-soluble fragments, generating new small molecule compounds that ultimately decompose into water and carbon dioxide.

The field of biodegradable food boxes

Biodegradable food boxes, also known as biodegradable food boxes, are environmentally friendly food packaging that can naturally degrade into smaller compounds under certain conditions, ultimately entering the ecosystem without causing long-term environmental pollution. Compared to traditional plastic lunch boxes, biodegradable lunch boxes have less impact on the environment.

These lunch boxes are usually made of biodegradable materials, which can come from plants such as starch, cornstarch, wood fiber, etc., or other natural ingredients. Biodegradable food boxes will decompose under certain humidity, temperature, and microbial action, ultimately transforming into water, carbon dioxide, and organic matter, and integrating with the environment. These biodegradable lunch boxes have positive implications in reducing plastic pollution and protecting the environment, as traditional plastic lunch boxes often take decades or even centuries to decompose.

Shortly, biodegradable plastics will replace traditional plastic products, ensuring safety and environmental protection.
