Technical Field

The invention relates to the technical field of biodegradable plastics, in particular to a screening device for preparing biodegradable plastics.

Background

Biodegradable plastics refer to a class of plastics that are degraded by the action of microorganisms such as bacteria, molds (fungi), and algae that exist in nature. The ideal biodegradable plastic is a high molecular material which has excellent service performance, can be completely decomposed by environmental microorganisms after being discarded, and is finally inorganic to become a component of carbon circulation in nature.
