[UVLED cold light source curing machine] is widely used, its high efficiency, environmental protection, low energy consumption and other characteristics are welcomed by customers, in fact, UVLED cold light source curing machine has an important feature is low thermal effect, no radiation. It is precisely because of the low thermal effect of UVLED cold light source, many inks have a special preference for it. Here I take a label printing technology that is more sensitive to heat as an example.
Advantages in heat shrink label film printing applications
Heat shrinkable film label is a kind of film label printed on plastic film or plastic tube with special ink. In the process of labeling, when heated (about 70 ° C), the shrink label will quickly shrink along the outer outline of the container and cling to the surface of the container. Heat shrinkable film label mainly includes shrink sleeve label and shrink wrap label. Shrink tube label is a tube label made of heat shrink film as the base material, which is convenient to use and is very suitable for special-shaped containers.
Shrink film label is a part of the label market, is currently in rapid growth, the market share continues to expand, is expected to grow at an annual growth rate of about 15%, much more than the ordinary label market of about 5% of the annual growth rate, the development potential is huge, become a bright spot in the label printing industry forecast in the next five years the domestic shrink film market will grow at a rate of more than 20%.
The production of heat-shrinkable film labels has high technical requirements. For ordinary water-based and solvent-based inks, the drying temperature is too high, and the material will shrink. The temperature is too low, the ink drying is not thorough enough and other problems, so the process is quite complex, the scrap rate is high. For the uvled cold light source, under the action of ultraviolet energy, the polymer material forms a network crosslinking in an instant, the ink is quickly cured, and the temperature of the printing material is not affected, and the unique cold curing system is very suitable for the production of heat-sensitive material labels. Thus, UV light curing technology fundamentally solves the problem of heat shrinkable film labels.
The UVLED cold light source curing machine dries the printing ink, and the pure ultraviolet drying produces almost no heat, which also has many benefits for our environment. Under the action of energy, the polymer material forms a network crosslinking in an instant, the ink is quickly cured, and the temperature of the printing material is not affected, and the unique cold curing system is very suitable for the production of heat-sensitive material labels. Thus, UV light curing technology fundamentally solves the problem of heat shrinkable film labels.
