Biodegradable starch foam packaging technology is a kind of packaging material with environmental protection characteristics, which is made by using starch-based biomass material as raw material, through starch processing and molding technology and foaming process. This technology is based on starch-based materials, which are processed into granulated granular materials through high temperature and pressure processes, and then formed into foam packaging through foaming, pressing, and molding processes. Unlike traditional foam packaging, biodegradable starch foam packaging material does not pollute the environment when used and can be harmlessly disposed of by decomposition of living organisms through natural degradation.

Biodegradable starch foam packaging technology has a wide range of applications. In daily life, it can be used to protect and package cakes, fruits, vegetables, tableware, toys and other fragile items; in the industrial field, it can be used to package various industrial products, such as bottled beverages, furniture, electronic products, etc. At the same time, the technology can also be used to prepare agricultural fertilizers, soil biological improvers and other products. With people's increasing awareness of environmental protection, the application prospect of biodegradable starch foam packaging technology is very broad.
