What are the influencing factors of PLA degradation?

2021-11-05

What are the influencing factors of PLA degradation? Biodegradable plastic bag refers to a material that can be degraded into low molecular weight substances by microorganisms or their secretions under certain conditions.


The degradation effect of biodegradable plastic bags is usually expressed by the weight loss rate of its degradation. By adding easily degradable materials to pure bioplastics, a blended biocomposite material is prepared, which can improve the biodegradability of bioplastic bags under composting conditions.


The pH of the soil environment is different, and the biodegradation effect of the material is also different. The pH value of different soils affects the activity of microorganisms and the degrading enzymes secreted by the microorganisms, thereby affecting the degradation rate. The pH value is also a factor that affects the biodegradability of biological materials under soil conditions.


Biodegradable plastic bag PLA can form a weakly acidic environment on the surface of the product, which has a basis for bacteriostasis and mildew resistance. If it is supplemented with other antibacterial agents, it can achieve an antibacterial rate of more than 90%, and can be used for product antibacterial packaging.


Dongguan Sengtor Plastic Products Co., Ltd. has been focusing on the production of biodegradable plastic bags for many years, using PLA biodegradable materials. Under composting conditions, the product can achieve biodegradation within 90-180 days. It can be decomposed into carbon dioxide and water, plastic particles will not be produced, and there will be no pollution, which will effectively solve the problem of environmental pollution. In the future, Sengtor brand will do its best to provide green, healthy and warm products for every quality family! Welcome customers to inquire!
