Analysis of three kinds of wine packaging post-press processing technology

BAIDU_CLB_fillSlot("858283");

Post-press processing technology is a "library" for the differentiation of contemporary wine packaging.

Embossing technique

The embossing technology is widely used in gold and silver cardboard and aluminized paper. It can make the printed image on the surface of the wine box show excellent visual effect under the stamping of embossing equipment, and it also has strong Anti-counterfeiting function.

2. "Mold cutting + pressure bump" technology "

The die-cutting + embossing technology can combine two separate processes, "die-cutting" and "pressing and embossing" into a process of "die-cutting + embossing" technology. Under the same pressure conditions, it can achieve die-cutting. The effect of the type can also achieve the bump effect. This technology can effectively improve the utilization rate of the equipment and reduce the printing cost of the wine box.

3. "hot stamping + pressure bump" technology

In recent years, the "hot stamping + embossing" technology has gradually emerged in the field of post-press processing of wine boxes.

(1) Advantages

The "hot stamping + pressure bump" technology has good hot stamping quality, high hot stamping accuracy, and the hot stamping edge is clear and sharp, and the surface gloss is high. It can use the etching or engraving technology to make the image of hot stamping and embossing into a female mold and a male mold. The two processes of “hot stamping” and “pressing and embossing” can be completed at one time, which greatly reduces the possibility of overprinting. The waste products that are not allowed to be produced improve the production efficiency and processing quality.

(2) Quality influencing factors

Temperature, pressure and speed are the three major elements of the "hot stamping + embossing" technology. Only by controlling the relationship between the three can ensure good hot stamping quality.

The hot stamping speed is actually the contact time of the hot stamping product with the electrochemical aluminum, that is, the heating time of the electrochemical aluminum. The faster the hot stamping speed, the shorter the heating time of the electrochemical aluminum, the faster the hot stamping temperature will fall, thus affecting the hot stamping fastness; the slower the hot stamping speed, the longer the heating time of the electrochemical aluminum, the hot stamping temperature The slower the drop, the better the hot stamping.
