Thermal Rolls 80mm by 79mm - 50 Pieces Ideal

Another parameter you cannot ignore is the thickness of thermal paper. This measurement is given in microns, where 1 micron = 1/1000 of a millimeter. This can be confusing, as different sheets may weigh the same in GSM but have different thicknesses in microns. For example, a piece of 58gsm thermal paper and a piece of 60gsm may be the same thickness. You cannot think a higher GSM indicates a thicker paper; a lower GSM indicates a thinner paper. This is due to several factors during the manufacture of the paper, including the type of coating on the paper, the amount of virgin fibers used, or the bulkiness of the raw material.
