Do Bio Plastic Bags Release Harmful Substances During Decomposition?

The main feature of truly biodegradable plastic packaging bags is their ability to degrade in the natural environment and convert into compounds such as CO2, water, and organic matter, which helps reduce damage to soil and water sources and meets the requirements of sustainable development. Compared with traditional plastic packaging bags, biodegradable plastic packaging bags can reduce the impact of plastic pollution on the environment.

However, bio plastic bags, despite being promoted as biodegradable, products that do not meet international standards and do not meet standards may release harmful substances during their production and use. During the process of biodegradation, substrates and degradation residues may be released, which may contain harmful substances such as heavy metals and other substances. The release of these harmful substances mainly depends on the content of chlorine and bromine in plastics. If the content is high, toxic and harmful gases may be produced during the production process. These harmful substances may pose potential pollution risks to soil and water sources. In addition, some so-called biodegradable plastics do not actually completely degrade during decomposition, but instead split into smaller plastic particles that are more hazardous and do not reduce their actual toxicity.

In addition, the quality and safety risks of biodegradable plastic bags also include the possibility that their relative biodegradation rate may not meet national standards, which may lead to their accumulation in soil, affecting the absorption of nutrients and water by crops, resulting in reduced yields, and also posing a threat to animal survival. Therefore, when purchasing and using biodegradable plastic products, consumers should ensure that the products comply with national standards and avoid using inferior products to reduce potential health and environmental risks.

Secondly, biodegradable additives added to plastic packaging bags may also produce harmful substances. The addition of biodegradable agents can accelerate the degradation of plastics, but some biodegradable agents themselves may contain harmful components to health or produce harmful substances. Although additives are usually thoroughly mixed during packaging bag preparation, there is still a certain degree of residue present. In addition, the production process of biodegradable plastic packaging bags may also produce some harmful substances, such as carbon dioxide and sulfur dioxide emissions.

As one of the largest biodegradable bag production bases in China, Huawei Company actively responds to the global "plastic ban" policy call and is committed to the research and development, production, and sales of fully biodegradable material technology. The HW series developed and produced by the company is a type of green and environmentally friendly thermoplastic resin. It is made of PBAT as the base material, modified with starch and calcium carbonate, and produced through melt seeding plasticizing extrusion technology. The material does not contain polyolefin plastics and can be degraded under specific conditions such as natural or soil fertilization, becoming harmless substances such as carbon dioxide and water.

We have obtained domestic and OK COMPOST certifications, as well as degradation certifications from countries or regions such as the European Union (DIN CERTCO, TUV), the United States (BPI), and Australia (ABA).

Our products are exported to overseas markets and have been recognized by many countries and regions. Our goal is to bring reliable products to the world, give our future generations an environmentally friendly future, reduce carbon emissions, and control white pollution.
