US Patent:

8647717, Feb 11, 2014

Filed:

Aug 2, 2013

Appl. No.:

13/958086

Inventors:

Sven S. Arenander - Richmond VA, US
Bruce W. Babcock - Charleston SC, US
David H. Hawes - Raleigh NC, US

Assignee:

MeadWestvaco Corporation - Richmond VA

International Classification:

B05D 3/02

US Classification:

4273722, 1563063

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.
