Description

technical field [0001] The invention belongs to the technical field of environment-friendly materials, and in particular relates to an environment-friendly packaging material and a preparation method thereof. Background technique [0002] With the rapid development of economy, the pollution brought by industrialization is also increasing. During the preparation process of packaging materials, a lot of pollution will also be generated. In addition, many of the prepared packaging materials are not environmentally friendly. For example, many packaging materials themselves have great pollution to the environment and are not easy to decompose. As society and people pay more and more attention to the environment, environmentally friendly packaging materials have emerged as the times require. [0003] Environmentally friendly packaging materials need to have high tensile strength and high tensile modulus without polluting the environment, and can effectively meet the needs of pac...
