According to the structure of the adhesive, according to its own characteristics, some special printing can be carried out to achieve a certain anti-counterfeiting effect.
1. The back of the label is printed. The back printing of adhesive labels is a new process in sticker printing, and it is also a special process. It refers to the printing of ink or paint on the adhesive surface of a self-adhesive material. A small amount of text or pattern is printed on the adhesive surface to make it a double-sided label. When affixed to a clear bottle or glass with clear liquid, the printed text on the back of the label can be seen through the transparent bottle or glass. In this way, the positive and negative sides of a label can each play different promotional roles, which saves both the label material and the cost, and also enables the product to have a special decorative effect. Due to the special structure of the double-sided label, it can play a certain anti-counterfeiting effect. Of course, if you print some microtext on the back or make some dark notes, you can achieve a professional anti-counterfeiting effect.
2. Two-way and reverse printing of stickers. Unlike the double-sided label formed by printing graphics and graphics on a self-adhesive adhesive, a two-way label refers to printing multiple times on a transparent film to make the appearance of a double-sided label. The reverse label is a special case of a two-way label, that is, after the reverse image is printed on the film, only the white ink or the composite white paper is printed and the second layer of the positive image is no longer printed. Due to the special nature of its own printing, it has a certain anti-counterfeiting effect.
3. Adhesive security. Our knowledge, whether it is the manufacture of corrugated boxes, the processing of composite films, the sealing of packaging boxes, the production of stickers, the sticking of trademarks, are all due to the paste technology. Obviously, it can use adhesive technology to achieve certain anti-counterfeiting effect. However, there are no examples of direct use. Therefore, this article will only discuss some adhesive labels.
Almost all packages are labeled with labels. In terms of adhesive labels, there are some that do not damage the package when it is removed. Some labels are destroyed when they are peeled off, and the adhesive is also damaged. package of. Then one situation achieves the purpose of packaging destruction. The old packaging cannot be reconstructed to counterfeit, thus achieving the purpose of destructive security packaging.
The packaging of the wine box is usually sealed with a label. If the adhesive of the label can be correctly selected, the label and the packaging box can be destroyed at the same time when the box is opened. In general, paper labels and paper boxes are easier to break when they are opened. Because the homogeneous material is easy to bond firmly, and the adhesive is also easy to choose. The sticky box between different materials is more difficult, first, it is difficult to find a suitable adhesive; second, the strength of the adhesive is not high enough, ie, the adhesive is not strong. At present, all the surface materials of the wine boxes are mostly plastic films. Therefore, the labels of the wine boxes also use plastic films, and it is best that the same type of plastic film is used. In the design, we should pay attention to two points: the bond strength between the surface material of the wine box and the inner layer is lower than the bond strength of the label; second, the tear strength of the label is higher than that of the surface layer of the wine box. The purpose of tear strength is to easily break the box when opening the box.
4. Destructive security of labels. It is when the consumer takes the goods that the labels are destroyed, so that the old labels can no longer be used, so as to achieve the purpose of anti-counterfeiting. In order to achieve this goal, it is necessary to consider that the position of the labels is always.
1 Tear label anti-counterfeit: An example of label destructive security, the label is attached before the bottle mouth is sealed, the label is placed slightly on the top, and then the lid is closed and sealed. When the bottle is opened, the label is destroyed under the rubbing and tearing action of the broken twisted cover, and the label cannot be used to achieve the purpose of anti-counterfeiting.
2 seal label anti-counterfeit: The label is used as a seal, with destructive anti-counterfeiting features. For example, there is a cigarette on each packet of cigarettes. When you smoke, you first must (and must) tear the cigarette off. Therefore, there is no problem with the use of cigarettes. Attach the label to the bottle and cap. When the bottle is opened, the label is destroyed and cannot be used again. It has a destructive anti-mite function.
3 The sticker is used as a printing material. As long as the material permits, various anti-counterfeiting technologies can be applied to it. Such as bar code anti-counterfeiting, telephone security, laser anti-counterfeit, holographic anti-counterfeiting, the main security, composite printing, multi-color printing security waiting, such as composite printing security.
4 The same machine, according to the needs of the process can be arbitrarily combined into several composite printing processes, such as silk screen plus flexo, silk screen plus gravure, flexo and stamping. For example, the screen printing on a certain part of the label can avoid white spots and uneven ink on the surface, while the part of the screen adjustment text is printed on flexo printing dots to improve the clarity. The composite printed labels have a strong three-dimensional effect and are clearly structured. Not only are they of good quality, but they also make counterfeiters unsure of their specific printing processes and thus have anti-counterfeiting effects.
5 The use of a variety of anti-counterfeiting technologies for printing on self-adhesive materials can achieve the purpose of anti-counterfeiting, and the anti-counterfeiting adhesive materials also increase the anti-counterfeiting capabilities of the self-adhesive labels. At present, there are mainly the following: Easy shredding adhesive materials, fragile film adhesive materials, word film anti-counterfeiting film adhesive materials, composite fabric stickers, security anti-counterfeiting adhesive materials, security label materials, No fluorescence, paper fluorescent paper stickers material.
Among them, the surface materials of the first two kinds of materials are extremely fragile by itself and high-viscosity adhesives are used. The adhesive strength is greater than the strength of the paper itself. Therefore, the labels produced by the two materials cannot be peeled off after being attached to the products. , One-time use, so that counterfeiters can not use genuine labels to sell counterfeit goods. The word film anti-counterfeiting film adhesive material is a kind of PET film processed by a special process. The surface is first printed with “VD” or other handwriting, and then the adhesive is applied. The adhesive also has strong adhesiveness, and the label thereof is made of it. When affixed to the product and then reopened, the “VD” and other writings pre-printed on the film coating side are separated from the label face material, and can be left at the labeling position of the product as a sealing label, which can verify whether the product packaging has been It was dismantled to achieve the purpose of security and anti-counterfeiting, and the anti-counterfeiting principle of the composite fabric adhesive material is similar to that of the word film anti-counterfeiting film adhesive material. However, the composite fabric layer is a double-layered polystyrene formed of a transparent polystyrene film compounded on a white polystyrene expanded material. When the label thereof is attached to the commodity and then reopened, the double-sided layer material is layered. The puffed layer is still firmly adhered to the surface of the product and it has been proved that the package has been disassembled. The security anti-counterfeiting adhesive material is a special metal film adhesive material, and its hologram can be designed according to the needs of users. The security tag is a kind of magnetic tag used by shops and supermarkets. The tag is filled with metal conductors. After the payment is made on shopping, the tag can be degaussed by using electric induction in batches. The tag without degaussing will automatically connect the alarm bell when passing through the security gate. Effectively prevent theft of goods. The non-fluorescent, low-fluorescence paper sticker material does not contain or contains only a small amount of fluorescent substances in the face sheet of the label. It is specially used for the printing of ultraviolet photosensitive inks and displays under the irradiation of an ultraviolet lamp to make an anti-counterfeiting purpose.
Labels made of self-adhesive materials are used in middle and high-grade liquors and cosmetics:
1. Wine
1 High-tech anti-counterfeiting: As Moutai adopts Canada's bass anti-counterfeiting technology company's high-tech anti-counterfeit labels attached to the bottle mouth, anti-counterfeiting labels look at different angles, there are three kinds of variable color optical anti-counterfeiting effect (red, yellow, green) Each bottle of wine is equipped with a UV anti-counterfeit checker and instructions for use. Under UV light, the anti-counterfeiting label can present completely different visual patterns.
2 Sealed label anti-counterfeiting: A special anti-counterfeit label is attached to both ends of the wine box, and the label is one-time. The box was opened and the security label was also destroyed. Most of these labels use direct visual inspection of laser holographic anti-counterfeiting labels. This anti-counterfeiting label is made by using holography technology, together with a one-time use of materials. In the most light or light, seven colors of red, orange, yellow, cyan, blue, and violet can be diffracted, and the logo is beautifully displayed for visual inspection. Identification.
3 dark-type anti-counterfeiting: In the wine label or wine box on the pattern of words deliberately left a mark or form a certain rule. For example, in the dot indentation of the label of the wine, it looks like a pile of irregular dots, but when you look closely, you can see a certain type of text.
2. Cosmetics
1 Laser Marking: Also called "holographic" label, it has two kinds, destructive and non-destructive. The general outer packaging is destructive. After the packaging is unpacked, it cannot be restored.
2 Telephone anti-counterfeit: A set of digital is printed on the logo. After you know the number by cutting or uncovering, type the input phone number one by one and you will get a language response to determine the identity of the product.
