In recent years, words such as fully biodegradable and degradable have frequently appeared before our eyes. Why are more and more companies and countries optimistic about fully biodegradable materials, and what are the reasons for their development?Many degradable materials seen on the market cannot be completely degraded and the cycle is very long, because the main raw material is starch, which is characterized by being difficult to degrade, and the bags made of starch have low tensile strength, which is not conducive to repeated use.Today we are going to talk about fully biodegradable materials, the raw materials of which are PLA andPBATMade, under the composting conditions of the natural environment and the action of microorganisms,180It is completely degraded into water and carbon dioxide, and will not pollute the soil and the environment.
