The work aims to prepare a kind of thermal insulation packaging material with the aerogels/aluminum silicate fiber, and study its thermal conductivity. The thermal insulation packaging material was formed by the vacuum filtration and dried by the microwave heating. The major factor that affected such thermal insulation packaging material was obtained by the orthogonal experiment. The measured results of the thermal conductivity indicated that, the heat conductivity coefficient of the optimal formula in the orthogonal experiment was 0.0164 W/(m•K) and conformed to the temperature-controlled packaging requirements. The heat conductivity coefficient decreased with the addition of silica aerogel. The heat conductivity coefficient of the material could reach 0.013 W/(m•K) to the minimum within the optimal volume density range of 51.29~55.09 mg/cm3. The proposed method expands the application range of aerogels and aluminum silicate fiber material in the packaging industry, and such application has certain practical significance for the agricultural product packaging.
