Thermal Paper Roll 80mm x 80mm: GSM/ Length/ Weight

80mm x 80mm Thermal paper roll size is very widely used in supermarkets, shopping malls, restaurants, banks, and many other industries. This site has been the most popular item among so many different paper roll sizes. We are sending around 15 containers of 80mm x 80mm thermal paper to overseas markets every month, and the demand is still keeping increasing. You may be curious about the 80mm x 80mm thermal paper GSM, length, and weight, or you may wonder what these terms mean. In this article, we will explain it to you.
GSM
GSM (Gram per Square Meter) or grammage, is one of the most important parameters in the paper industry. It basically indicates how many grams a square meter of paper weighs. You can calculate it simply by taking a square meter of paper and weighing it, for more information please visit us at https://buyrolls.com.
The standard gsm of thermal paper is 50gsm, 55gsm, 60gsm, 65gsm, etc.
Another parameter you cannot ignore is the thickness of the paper sheet. 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 a number of factors during the manufacture of the paper, these can include the type of coating on the paper, the number of virgin fibers used, or the bulkiness of the raw material.
Common paper’s weights and their approximate thicknesses are:
50gsm = 50-55mics
55gsm = 58-62mics
58gsm = 65-75mics
60gsm = 70-80mics
65gsm = 80-90mics
For thermal paper, it is usually to be sold in GSM since it is easier to use this to distinguish the paper’s grades. However, if you doubt a paper’s grade, you might wish to collect samples first to check the quality.
2. Length

A thermal roll is actually a cylinder. The unrolled cylinder’s perimeter is actually the paper roll’s length. You can get the paper length in several ways:
Ask your suppliers. Your suppliers should know the length of the paper roll size.
Measure it by yourself. You can unroll the paper rolls by yourself and measure it with a tape measure (yes, that could be a little difficult!).
Calculate it by yourself. It requires some math to calculate the paper length.
3. Weight
The plastic core’s weight is around 0.007kg, it can be ignored since it is very light and not significant. We can calculate the weight of a paper roll by the formula:
WEIGHT = WIDTH(W) X LENGTH(L) X GSM(KG/M²)

For 80mm x 80mm 60gsm thermal paper, the width is 0.08m, the length is 59m, and the grammage is 0.060kg/m². With this formula, we can easily get a weight of about 0.285kg for an80mm x 80mm thermal roll.
