At present,Biodegradable mailing bags there is no unified international standardized definition of biodegradable plastic bags in the world,Biodegradable mailing bags but the definition of biodegradable plastic bags is usually: under certain environmental conditions,Biodegradable mailing bags its chemical structure changes significantly,Biodegradable mailing bags and standard test methods are used
Plastic bags that can measure changes in material properties. The molecular chains of biodegradable plastic bags can be biodegraded by microorganisms in the garbage disposal system or the natural environment,Biodegradable mailing bags and finally become carbon dioxide (or methane) and water, which enter the biological combined cycle The process is completely absorbed by the environment without leaving any polymer.
Most synthetic pure polymers have the ability to resist microbial attack. But additives (such as plasticizers,Biodegradable mailing bags slip agents,Biodegradable mailing bags pigments and antioxidants, etc.) reduce this ability. Plasticizer residual fatty acids such as stearate can be degraded by microorganisms and cause damage to the polymer surface and performance and even the basic structure.
