Thermal paper, also known as thermal sensitive paper, is a type of paper that is printed on through the use of heat. It has many applications in industries such as retail, hospitality, healthcare, and banking. The paper has thermal coating on one side and a base paper on the other side. When the paper is subjected to heat, the coating changes color, forming the printed image. The thickness of the thermal paper is measured in millimeters, and there are different types of thermal papers with varying thicknesses. The question is, do the different millimeters of thermal papers have any difference? The answer is yes.
The thickness of the thermal paper affects the way it reacts to heat. The thicker the paper, the more resistant it is to heat. There are three types of thermal papers available in the market; 55 GSM, 60 GSM, and 70 GSM.
The 55 GSM thermal paper is the most commonly used paper. It is thinner than the other papers, which makes it more susceptible to wear and tear, and it is not very durable. This paper is suitable for applications where short-term receipts are required, such as parking tickets, coupons, and receipts.
The 60 GSM thermal paper is thicker than the 55 GSM and is more durable. It is an ideal choice for printing receipts that need to last for a few days or weeks, such as in retail or restaurants.
The 70 GSM thermal paper is the thickest and most durable of the three. It is ideal for printing receipts that need to be kept for a longer period of time such as in healthcare and banking. The paper is resistant to damage and can withstand high temperatures, making it suitable for use in environments where the temperature can be high.
Apart from the thickness, the different millimeters of thermal paper also affect the print quality. The thicker the paper, the finer the print. The 55 GSM paper produces a slightly blurry print, while the 70 GSM paper produces a sharper and clearer print.
In conclusion, there are, indeed, differences between the different millimeters of thermal paper. The thickness of the paper affects its durability, resistance to heat, and print quality. The 55 GSM paper is suitable for short-term receipts, the 60 GSM paper is suitable for medium-term receipts, and the 70 GSM paper is suitable for long-term receipts. The choice of paper should depend on the application and the required durability and print quality. Therefore, when selecting thermal paper, it is important to consider the intended use and select the paper with the appropriate millimeter thickness.
