Abstract
A method for preparing a thermo-insulating packaging material including steps of providing a first paper-based substrate, applying a fluid thermal-insulating composition onto the first paper-based substrate, the thermal-insulating composition including a filler, an organic binder, a plasticizer, and water, applying a second paper-based substrate over the thermal-insulating composition such that the thermal-insulating composition is positioned between the first paper-based substrate and the second paper-based substrate to form a structure, and drying the structure.
