The different layers of our thermal paper

At Ricoh, our thermal papers consists of five different chemical layers that create the unique thermal and protection properties. The following is an overview of these layers. Please note that this overview does not include information on the adhesive layer or the Silicon release liner.

Top coat
Protection of thermal image. Image preservation and pre-printability
Thermal coat
Image density, sensitivity, and preservation
Under
Smoothing coat that determines sensitivity, density and brightness of the image
Basis paper of film
Back coat
Protection against outside aggressions

Thermal paper is relatively fragile. Because of this, certain precautions must be followed to prevent any premature deterioration during storage or while handling until the end of its use.

Care in Storage

Before unpacking:

Ricoh Thermal papers can be unused without any deterioration for a long time after production if they are stored in the dark at temperatures that do not exceed 95° F and a relative humidity not exceeding 85%.

After Unpacking:

In addition to the above care, avoid long term exposure to direct sunlight and strong fluorescent light sources. These light sources can generate some background coloration if left unchecked. Do not place Ricoh Thermal paper near heat sources.

Care in Handling

Avoid any contact with materials composed of, or containing, solvents or plasticizer. Avoid/ minimize any scratching or rubbing as this may cause unwanted thermal revelation. Avoid any contact with water.
