One of the most notable features of UVLED light curing technology is the low thermal effect. It is also because of the low thermal effect of UVLED light curing technology that label printing companies are particularly fond of it under the curing light source. Let me make a statement with a label printing technology that is more sensitive to heat.
Heat shrinkable film label is a film label printed on plastic film or plastic tube with special ink. During the labeling process, when heated (about 70 ℃), the shrink label will quickly follow the outer contour of the container Shrinkable, close to the container surface, heat shrinkable film labels mainly include shrink sleeve labels and shrink wrap labels. Shrink sleeve labels are made of heat-shrinkable film as the base material, and are made into cylindrical labels after printing. It has the characteristics of convenient use and is very suitable for special-shaped containers.
Heat shrinkable film labels are a part of the label market. They are currently undergoing rapid growth. The market share is constantly expanding. The expected annual growth rate is about 15%, which greatly exceeds the annual growth rate of about 5% in the ordinary label market. The development potential is huge. Become a bright spot in the label printing industry. It is predicted that the domestic heat shrinkable film market will grow at a rate of more than 20% in the next 5 years.
The production of heat-shrinkable film labels has high technical requirements, especially when printing heat-shrinkable films, how to control the drying temperature is very important. For ordinary water-based and solvent-based inks, the drying temperature is too high , The material shrinks thermally; if the temperature is too low, the ink does not dry thoroughly, resulting in problems such as adhesion and dirt on the back. Therefore, the process is quite complicated and the scrap rate is high. For UVLED light curing technology (UV surface light source), under the action of ultraviolet energy, the ink makes the polymer material form a network crosslink in an instant, the ink cures quickly, and has no effect on the temperature of the printed material. The unique cold curing system is very suitable Production of labels for thermal materials. In this way, the UVLED light curing technology has fundamentally solved the problem of heat shrinkable film labels being afraid of heat.
Recently, many companies have adopted UVLED light curing technology in inkjet printers. The curing equipment completely uses UVLED to dry the printing ink. Pure ultraviolet drying hardly generates any heat, even suitable for thermal media such as acrylic plastics. print.
