Abstract

The invention relates to the technical field of environment-friendly packaging materials, and in particular, relates to an environment-friendly degradable cushion packaging material and a preparationmethod thereof. The environment-friendly degradable cushion packaging material is prepared from the following raw materials in parts by weight: 1 to 6 parts of a composite foaming agent, 40 to 70 parts of plant fiber powder, 50 to 80 parts of edible starch, 30 to 50 parts of wheat flour, 40 to 70 parts of vegetable oil, 0.5 to 5 parts of an emulsifying agent and 150 to 250 parts of deionized waterA. The degradable cushion packaging material disclosed by the invention is pollution-free in production and use processes, is extremely easy to degrade, is green and environment-friendly, also has controllable elasticity and good buffering performance, and can effectively protect products inside the package; in addition, the preparation method is simple and efficient, convenient to operate and control, high in product quality, beneficial to industrial production, free of generation of three wastes in the production process, and green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of environment-friendly packaging materials, in particular to an environment-friendly degradable buffer packaging material and a preparation method thereof. Background technique [0002] The main function of the foam plastic is to fix the product in the carton to avoid the shaking of the product during transportation. Moreover, because the foam plastic has good elasticity, it can also play a certain buffering role and reduce the damage of the product due to collision. destroy. In the production process, the density and elasticity of the foamed plastic can be regulated by controlling the process parameters such as the delivery time, so that it is suitable for products of different weights and has strong adaptability, so it is widely used in product packaging. However, as a disposable material, foam plastic has extremely poor degradability, and it is extremely difficult to degrade when it is discarded in the ...
