The same thermal sticker is often used in POS equipment, which has a water-proof function. The material is different from that of the thermal sticker. After the sticker is heated, leaving a thermal trace on the surface is equivalent to the printing effect. The thermal sticker is basically printed and then overprinted on the equipment. It is often used in parking list, beverage stores, food factories, etc., without double-point A thermal paper rolls. Welcome to call and negotiate.
