Problems solved by technology

[0003] However, the degradation rate of environmentally friendly plastics in the prior art is actually relatively slow, and the polymerization is relatively difficult
Strength and high temperature resistance are significantly lower than PE plastic bags. Some environmentally friendly plastics can be decomposed by microorganisms, but because they have no nutrients themselves, it is difficult for microorganisms to multiply rapid

Description

technical field [0001] The invention relates to the field of environmentally friendly plastic processing, in particular to an acidophilic microorganism degradable plastic masterbatch and a manufacturing method thereof. Background technique [0002] Environmentally friendly plastic is the abbreviation of various biodegradable plastics. With the development of science and technology, various materials that can replace traditional PE plastics have emerged, including PLA, PHAs, PBA, PBS and other polymer materials. [0003] However, the degradation rate of environmentally friendly plastics in the prior art is actually relatively slow, and polymerization is relatively difficult. Strength and high temperature resistance are significantly lower than PE plastic bags. Some environmentally friendly plastics can be decomposed by microorganisms, but because they have no nutrients themselves, it is difficult for microorganisms to multiply rapidly to accelerate the decomposition process, ...
