In the eyes of mass consumers, Labels are just a tool for identifying products and analyzing their main components. In the eyes of brand owners, labels are crucial to the product, and it is far greater than what consumers see. Among the many functions of the label, anti-counterfeiting is an important function that cannot be ignored.
Friends who often eat "old godmother" may know that it is getting harder and harder to find a bottle of authentic "old godmother" on the shelves selling all kinds of hot sauce in the supermarket, because various counterfeit products are stacked, which makes "old" The godmother had to change his anti-counterfeiting technology again and again. Probably in 2005, "Laoganma" once launched an anti-counterfeit label, claiming that as long as it was painted with a pen in the designated area, it would display the word "authentic", which made it smash hit, but this anti-counterfeiting technology did not persist. How long has it been successfully copied by a counterfeiter? The pursuit of genuine and fake goods will always be like a game of cats and mice, so the importance of anti-counterfeiting function is self-evident. Below, the author will introduce you to several mainstream label anti-counterfeiting technologies on the market.
Highly recognized ink anti-counterfeiting
Anti-counterfeiting ink is an important part of the anti-counterfeiting technology system. Anti-counterfeiting ink refers to the anti-counterfeiting ink. It is also composed of coloring materials, binders and ink additives. However, special anti-counterfeiting materials are added to the ink binder. Specially processed, it is special Printing ink. The mainstream anti-counterfeiting inks on the market generally include ultraviolet fluorescent ink, daylight color changing ink, heat sensitive ink, chemical reaction color changing ink, water sensitive anti-counterfeiting ink and the like. Products printed with UV fluorescent inks, illuminated by special anti-counterfeit fluorescent lamps, will be brightly printed with anti-counterfeit fluorescent inks, showing bright red, orange, yellow-green or green fluorescence, high fluorescence intensity and good printing adaptability. The light disappeared quickly. After the purple light was turned off, the light disappeared instantly. Daylight color-changing inks will appear in the light of daylight. The thermal ink changes color after heating, and the pattern is restored after cooling (as shown in Figure 1), which is a reversible color ink.
The advantage of the anti-counterfeiting ink is that under normal observation conditions, the label is in a normal state, and when anti-counterfeiting is required, the authenticity can be easily and quickly identified by a specific means. However, anti-counterfeiting inks also have fatal shortcomings, because special inks have anti-counterfeiting functions. A large part of the reason is that special inks belong to the scope of national control, and the threshold for purchase is high, that is to say, manufacturers with special inks are less in the market, so Achieve a certain anti-counterfeiting effect. However, at present, anti-counterfeiting inks have been used in a large number of anti-counterfeiting labels and packaging. The threshold for purchase has become lower, and even without substantial control, the anti-counterfeiting value is gradually reduced.
Optical anti-counterfeiting technology
Speaking of optical security labels, you can't rely on holographic (or laser) anti-counterfeit labels. Currently, various holographic (or laser) labels on the market are mixed, but not all laser labels can be called optical security labels. All laser tags are anti-counterfeiting. Aside from the purely decorative through-the-ray laser label, we are talking about the optical anti-counterfeit label with a high level of anti-counterfeiting.
The anti-counterfeiting strength of hot stamping labels has been much higher than that of ordinary self-adhesive labels. For example, Yunnan Baiyao, which has just been replaced with a new label in the past two years (as shown in Figure 2), the anti-counterfeiting label on the packaging is a hot stamping label. The label has good reflectivity under the side light, and the color is beautiful. The color of the color of the treasure phase is clear, evenly distributed in the circle, and the pinyin letters outside the circle are clear, and the strokes are uniform in thickness, which is an exquisite hot stamping label. High-resolution, three-dimensional true color, reflective angle discoloration, animated text icons, small house textures, pixel transformations, high-definition co-located visions, and pixel characters are all high-level optical anti-counterfeiting technologies.
In addition to the optical technology itself, optical security labels also have many special requirements in materials, such as high temperature resistance. When a general hot stamping label passes through a laser printer, the optical pattern on it will disappear, because ordinary optical hot stamping labels cannot withstand the high temperature of 180 °C, but Suzhou Impression Laser Technology Co., Ltd. can already produce such labels. .
In addition to hot stamping labels, optical anti-counterfeiting labels, as well as self-adhesive labels, transfer paper labels, single-use uncovering labels, fragile paper labels, etc., the superposition of various technologies and processes, so that the anti-counterfeiting strength of the labels can be Further improvement. It can be said that optical anti-counterfeiting technology is the most important member of the tag anti-counterfeiting family.
Although there are many applications, only the ever-evolving technology can get out of the mixed market. No single technology can be changed. Only by constantly exploring and researching can the label truly play the role of anti-counterfeiting.

Trolley luggage refers to luggage with trolleys and wheels. It is widely used because of its ease of use. At the same time, the trolley case is also equipped with a tie rod because of the box, which can be divided into single-tube tie-rod and double-tube tie-rod. The trolley case can be carried by hand or dragged. The wheels of the trolley case we usually use are basically located at the bottom of the box, but modern people have designed a new form of trolley case. The box is designed in the shape of a cylinder, and the wheels are The whole package is outside the box. This roller design makes this trolley case better adapt to different terrains. For example, you can easily go up and down stairs by pulling the box directly. In 2012, cloth cases, ABS hard cases, leather cases, PC, etc. were the main materials, and the usability was divided into three categories: directional wheels, universal wheels and the latest detachable universal wheel trolley cases.
