Abstract
Drying a planar substrate such as paper sheet goods for packing materials includes layering a phase change material (PCM) on a substrate, in which the substrate has a moisture content and adapted for moisture removal to form a planar medium. A drying process disposes the substrate adjacent to a plurality of rollers and heat the layered substrate to a predetermined temperature based on a specific heat of the PCM. The rollers advance the layered substrate in series through pocket ventilation regions between the heat transfer elements, such that the pocket ventilation regions permit drying of the substrate enhanced by the specific heat of the temperature sensitive material. Upon drying, the layered substrate forms the planar medium suitable for use as a packing medium or other suitable application. The pocket ventilation regions are based on the PCM to facilitate drying and eradication of moisture from the paper planar substrate.
