What is the degradation of biodegradable garbage bags?

What is the degradation of biodegradable garbage bags? In fact, biodegradation is not only related to the structure of the polymer, but also related to the types of microorganisms and the environment. Moreover, its degradation is also related to the way in which microorganisms adhere to the surface and the surface tension of the polymer, surface structure, material porosity, environmental disturbance, and erodible surface area.


The mechanism of biodegradation is mainly driven by microorganisms. The microorganisms first attach to the biodegradable plastic and use the biodegradable plastic for assimilation. then, after the polymer is hydrolyzed, the plastic is broken and degraded, so the metabolites and gas molecules of the biodegradable plastic are Release into the environment.

The degradation mechanism is different under different environmental conditions. PLA and PBAT can be degraded under natural environmental conditions, but the degradation rate is slower than the requirements of the standard degradation test under composting conditions. Studies have shown that the biodegradation level of plastics in the soil may be highly correlated with the diversity and abundance of microorganisms on the plastics.


Dongguan Sengtor Plastic Products Co., Ltd. uses advanced equipment in the industry and has solved a number of key technologies and indicators through an experienced production. The self-developed biodegradable garbage bags can be 100% biodegradable in nature and comply with EU and other countries The plastic ban standard has obtained the full biodegradable certificate under the compostable conditions of the EU EN13432 and the ASTM6400 standards. The delivery scenarios include hospitals, scenic spots, schools, airports, communities, supermarkets, convenience stores, restaurants, etc.
