Intelligent packaging technology and its development can be explained from the following aspects:
one Anti-counterfeiting packaging
Fake and shoddy products can be said to be a cancer on the market, which not only greatly reduces the direct economic benefits of counterfeit enterprises, but also harms the vital interests of consumers. With the development of science and technology, the clever and extensive counterfeiting technology has put forward updated requirements for anti-counterfeiting technology, taking into account the high technical content of anti-counterfeiting packaging and the expansion of traditional functions of packaging, it can be classified into "intelligent packaging".
The so-called "anti-counterfeiting packaging technology" is: mainly to the commodity as the object, the automatic packaging solution is not only an integral part of the anti-counterfeiting part, but also an integral part of the packaging technology. Therefore, anti-counterfeiting packaging has the general functional characteristics of anti-counterfeiting technology, and at the same time has its own characteristics suitable for commodity packaging.
At present, the anti-counterfeiting packaging means can be described as many, only anti-counterfeiting signs have more than one hundred, but from the overall analysis, anti-counterfeiting packaging technology focuses on the following aspects: anti-counterfeiting marks; Special material technology; Printing process; Packaging structure and other methods. The following technical means occupy the mainstream position.
(1) Laser hologram
The use of holographic printing technology to make anti-counterfeiting marks attached to the surface of packaging is currently a popular anti-counterfeiting means. The holographic image has a high technical content because it integrates the new achievements of laser, mechanics and physical chemistry. For most small batch counterfeiters, it is difficult to master a full set of manufacturing technology and purchase manufacturing equipment. So the effect of this technique is remarkable.
However, the stamped holographic anti-counterfeiting mark has not fully achieved its due function, and even forged marks have appeared.
Followed by the laser holographic technology processing with anti-counterfeiting function of new packaging materials and a higher level of holographic image identification technology. The holographic image technology of automatic opening and sealing box stamping system has better anti-counterfeiting function: high quality full color three-dimensional holographic technology; Complex dynamic hologram technology; Encryption holographic technology; Digital holographic technology; Special hologram carrier technology (such as hologram special imprinting materials).
(2) Laser anti-counterfeiting packaging materials
The laser-treated material has the functions of anti-counterfeiting and decoration, and changes the local anti-counterfeiting way of a small piece of laser holographic image identification to achieve the overall anti-counterfeiting effect. The whole package is processed by laser, plus the manufacturer's name, trademark, etc., showing a large area of subjectivity anti-counterfeiting, counterfeiters can not start. In addition, the laser packaging material can show colorful colors under the light irradiation, and the printing pattern, so that the appearance is bright, and the strange optical effect adds a new, strange and beautiful feeling to the packaging.
There are four categories of packaging materials after laser treatment: (1) Flexible packaging bags: using emerging technologies to produce laser film, and then composite with ordinary plastic film, plus printing to form laser material flexible packaging bags (called laser flexible packaging bags). 2 Hard packaging box: One is to first use emerging technology to produce laser film, and then composite with cardboard, plus printing to form a hard box. The other is first printed on a general cardboard box, and then combined with a laser-treated glazing film to form a glazing hard box. Laser paper: Laser paper is made directly on the paper. The production process of laser paper is difficult and the cost is high. But its advantages are: easy to print, easy to handle, no environmental problems; Some products must be wrapped in paper (such as cigarette boxes), especially suitable, such as cigarette boxes, bottle stickers, labels, tax strips, calendars, gift bags, etc. In order to increase the anti-counterfeiting effect, the manufacturer can use a special holographic pattern logo as a paper base pattern, and an automated production line coupled with product graphics to make a unique special wrapping paper. ④ At present, there is also a kind of hot stamping foil treated by laser - high-grade electrolytic aluminum products. The logo specially made with it can be displayed in multi-dimensional stereo. You can use the computer to design a dynamic picture, you can also reserve a "light spot" encryption, and make the main pattern in different angles to display different patterns. After the hot stamping foil is combined with the surface of the packaging, it is integrated with the packaging to achieve the dual effect of anti-counterfeiting and aesthetics
