The temperature resistance range of several types of commonly used label papers:
1. PET self-adhesive labels
PET is a fiber material with good It has hard ductility, can withstand certain high temperatures, withstand harsh environments, and resist corrosion by chemicals such as strong acids and alkalis. The commonly used fabrics include matte silver, matte white, bright silver, pure white and completely transparent.
The temperature resistance range of basic PET labels: -20℃~+120℃, the minimum labeling temperature is 10℃; the temperature resistance range of strong adhesive and cable PET labels: -20℃~+100℃, the minimum labeling temperature is 10℃ Standard temperature is 10℃.
2. PP self-adhesive labels
PP self-adhesive materials are the most common basic consumables in advertising. Depending on the coating, three types of black inks are supported for printing: weak organic solvent black ink, pigment ink and dye ink. Among them, the self-adhesive PP printed with weak organic solvent black ink is also often called outdoor self-adhesive or oil-soluble self-adhesive, and can be used outdoors without a film.
What is printed with color paste ink is called moisture-proof self-adhesive in the market. It can only be used indoors without sub-coating. What is printed with dye ink is water-soluble self-adhesive, which is not moisture-proof. When the coating is exposed to water, It melts instantly, so it must be covered with a film for indoor use. The temperature range of the label: -20℃～+80℃, the minimum labeling temperature is 7℃.
3. PVC self-adhesive labels
The temperature resistance range of general PVC labels: -10℃～+60℃, the minimum labeling temperature is 10℃; the resistance of strong adhesive PVC labels Temperature range: -20°C ~ +80°C, minimum labeling temperature 7°C; temperature range of high-temperature PVC labels: -20°C ~ +280°C (280°C for ten minutes, 320°C for 10 seconds), minimum labeling temperature of 7°C . The temperature resistance range of ultra-low temperature PVC labels: -196℃～+165℃, the minimum labeling temperature is -40℃.
4. Thermal paper self-adhesive labels
Thermal printing paper is a kind of production and processing paper. Its manufacturing principle is to apply a layer of glue on high-quality base paper. Thermistor architectural coating” (thermistor fading layer).
The temperature resistance range of the thermistor label: -15℃～+60℃ (general three-proof), -50℃～90℃ (high-quality three-proof), the minimum labeling temperature is 7℃; according to the quality Different, the temperature resistance characteristics are not the same.
The temperature resistance range of removable thermal paper labels: -50℃～+90℃, the minimum labeling temperature is 7℃. "Removable" means that the label is attached to the object to be attached, and no strong glue remains on the surface of the object to be attached after the label is removed.
