The application of UVLED cold light source curing machine] is very extensive. Its characteristics such as high efficiency, environmental friendliness, and low energy consumption are highly welcomed by customers. In fact, the UVLED cold light source curing machine also has an important feature of low thermal effect and no radiation. It is precisely because of the low thermal effect of the UVLED cold light source that many inks have a special preference for it. Now, I will take a label printing technology that is relatively sensitive to heat as an example to illustrate. Advantages in the application of heat - shrinkable label film printing Heat - shrinkable film labels are thin - film labels printed on plastic films or plastic pipes using special inks. During the label - pasting process, when heated (around 70℃), the shrinkable labels will quickly shrink along the outer contour of the container and adhere closely to the container surface. Heat - shrinkable film labels mainly include shrink - sleeve labels and shrink - wrap labels. Shrink - sleeve labels are tubular labels made of heat - shrinkable films as the base material after printing. It has the characteristic of being easy to use and is extremely suitable for irregular - shaped containers. Heat - shrinkable film labels are a part of the label market. Currently, they are in a stage of rapid growth, with the market share continuously expanding. The annual growth rate is expected to be around 15%, which is much higher than the annual growth rate of about 5% in the ordinary label market. They have great development potential and have become a highlight in the label printing industry. It is predicted that the domestic heat - shrinkable film market will grow at a rate of over 20% in the next five years. The production of heat - shrinkable film labels has relatively high requirements for process technology. For ordinary water - based and solvent - based inks, if the drying temperature is too high, the material will undergo thermal shrinkage; if the temperature is too low, the ink will not dry thoroughly. Therefore, the process is quite complex and the reject rate is relatively high. However, for the uvled cold light source, under the action of ultraviolet energy, macromolecular substances form a network - like cross - link in an instant, the ink cures rapidly, and it has no impact on the temperature of the printing material. The unique cold - curing system is very suitable for the production of heat - sensitive material labels. Thus, the UV light - curing technology fundamentally solves the problem that heat - shrinkable film labels are afraid of heat. The UVLED cold light source curing machine dries the printing ink. Pure ultraviolet drying generates almost no heat and also has many benefits to our environment. Under the action of energy, macromolecular substances form a network - like cross - link in an instant, the ink cures rapidly, and it has no impact on the temperature of the printing material. The unique cold - curing system is very suitable for the production of heat - sensitive material labels. Thus, the UV light - curing technology fundamentally solves the problem that heat - shrinkable film labels are afraid of heat.
