PLA degradable plastic bags, fully degradable plastic bags, biodegradable plastic bags, degradable shopping bags

Recently, a national notice was issued banning and restricting the use of non-degradable plastic bags, disposable plastic tableware, disposable plastic straws, and other disposable plastic products by the end of 2020. With the successive upgrading of the "plastic restriction order," it will change the consumption pattern of disposable plastic products, bringing an ecological green tide to the market. The biodegradable plastic bag industry will become even more turbulent. Various plastic packaging bag industries have also developed biodegradable plastic bags, joining the ranks of environmental protection. So what exactly are biodegradable plastic bags? Let's follow Shunxingyuan Packaging, a professional flexible packaging manufacturer, to learn more. Biodegradable plastic bags are made of biodegradable plastics, which means that after these materials are discarded and enter the waste disposal process, they can be completely degraded under appropriate environmental conditions without harming the environment. Biodegradable plastics refer to plastics that are degraded in nature, such as soil, sand, freshwater environments, seawater environments, and under specific conditions such as composting or anaerobic digestion, by the action of naturally occurring microorganisms, and eventually completely degraded into carbon dioxide (CO2) or/and methane (CH4), water (H2O), mineral salts of the elements they contain, and new biomass (such as microbial corpses, etc.).

The materials of biodegradable plastic bags include biodegradable natural polymer materials, such as cellulose, starch, and paper, as well as bio-synthesized or chemically synthesized biodegradable plastics. These materials can be degraded through composting. A material, such as paper or plastic, if it claims to have composting ability, must state that the material is biodegradable and disintegrates in the composting system, and the compost must meet relevant quality standards, including low heavy metal content, no biological toxicity, and no obvious distinguishable residues. It should be noted that biodegradable plastics are not only degraded through composting. Completely biodegradable plastics can also be degraded under other conditions, such as soil and seawater in natural environments, if the conditions are suitable. However, the degradation rate is related to the chemical structure of the plastic, the product formula, and the degradation environmental conditions. According to existing experiments and literature, PHA, PBAT, PCL, and PBS materials are relatively easy to biodegrade under seawater, soil, and composting conditions. Under suitable room temperature and humidity, they can be completely degraded within 2-6 months; while PLA is relatively easy to biodegrade under composting conditions, but the degradation cycle or speed is relatively slow under seawater and soil conditions.

PBAT, PHA, PCL, and PBS can be completely degraded under normal climatic conditions with 5 months of burial and sufficient humidity, and will not affect plants; the degradation speed of PLA material is relatively slow, and the time is longer, but when blended with PBAT or PBS materials, according to experimental results, it can also be completely degraded in about half a year. PHA and PBAT materials can be completely degraded in about 30-60 days under simulated seawater conditions at 25℃±3℃. In addition, biodegradable plastics with benzene rings in the main chain are relatively stable. Many people may think that biodegradable aromatic polymers cannot be degraded by microorganisms, but because of the special chemical structure of biodegradable aromatic polymers, there are also microorganisms in nature that can degrade benzene rings, so they can also be degraded by microorganisms, and the toxicity of the degradation products will not harm the environment.

PHA、PBAT材料在模拟海水、25℃±3℃条件下，约在30~60天就能完全降解。

　　此外，主链含苯环的聚合物的可降解塑料相对来说稳定性高。许多人会以为，含苯环的生物降解塑料不能被微生物降解，但因为生物降解的芳香族聚合物其化学结构的特殊性，自然界也有可以降解苯环类的微生物存在，因此它也可以被微生物降解，且降解后产物的毒性也不会对环境造成危害。
