At present, there are more than ten types of anti-counterfeit labels commonly used in packaging:
1. Tamper evident seal
An exposed self-adhesive anti-counterfeit seal with a base material as a plastic film is a colored, wordless, self-adhesive plastic strip before being lifted; after being lifted, the colored handwriting can be seen on the paper, and the obvious visible on the plastic strip The colorless handwriting has the characteristics of one-off damage and one-off damage. It is mostly used in the fields of anti-counterfeit envelopes and electrical appliance warranty labels.
2. Fragile paper label
Use special fragile paper or fragile self-adhesive materials, which can be printed with trademarks, text descriptions and bar codes. After pasting on the packaging, it can not be completely lifted. Once lifted, the paper will be broken.
3. Integrated anti-counterfeiting and anti-indentation paper labels
The comprehensive use of various anti-counterfeiting technologies to make self-adhesive paper labels can strengthen the anti-counterfeiting function. In order to prevent the label from being lifted, replaced and reused, die-cutting indentation technology can be used to partially prevent the label from being uncovered, and cannot be recovered after being lifted.
4. Barcode technology label
There are many types of bar codes currently used, and anti-counterfeit bar codes mainly include one-dimensional bar codes and two-dimensional bar codes. Bar code technology can not only promote better and faster application, but also achieve the purpose of preventing famous products from being counterfeited and protecting the interests of consumers.
5. Laser hologram label
The application of laser holographic image technology in anti-counterfeiting packaging is mainly to print anti-counterfeiting labels and trademarks. The factors that affect the anti-counterfeiting performance of laser holographic labels are the types and locations of labels. The types of anti-counterfeiting labels for laser holographic images are as follows.
â‘ Sticker type
The holographic anti-counterfeiting graphic is made on the self-adhesive material, and it is not necessary to brush any adhesive when using, which has good mechanical adaptability. The biggest shortcoming is that it can be used repeatedly, and criminals can use old packaging and labels to make fakes.
â‘¡ Tamper-evident
It makes up for the shortcomings of ordinary self-adhesive labels. When the label is removed from the packaging, the holographic image of the label is unrecognizable and cannot be used again, which can prevent the use of old labels to make fakes.
â‘¢ Hot stamping type
It is a kind of holographic anti-counterfeit label that cannot be removed. The holographic anti-counterfeit label is stamped on the packaging material by a hot stamping machine, and integrated with it.
6. Anti-counterfeit polyester film label
Before peeling off, it is an aluminum foil wordless self-adhesive strip. After peeling off, there are obvious colored writing on the label paper and packaging materials.
7. Transparent PVC font anti-tamper universal label
It is a white non-sticky self-adhesive film label before being lifted, and there are obvious colored handwriting on the label and packaging materials after being lifted.
8. Transparent PVC security label
On the self-adhesive labels or other documents, the transparent laser holographic film with personalized information is attached, which does not affect the overall design and the original effect, but also adds anti-counterfeiting functions to make the label personalized.
9. Foam film label
It is a unique semi-gloss white film, which is composed of two layers of polystyrene film. The surface layer is a transparent film, suitable for printing; the lower layer is a white foam film that has been expanded. Use permanent acrylic adhesive. It has a good security and anti-counterfeiting effect. When the label is attached to the substrate and then lifted off, the two layers of film are separated, the label is torn, and the residue of the foam layer will be left on the packaging, which is difficult to remove. Suitable for use in humid environments, especially in the production and packaging of beverages, dairy products and other products, it has extraordinary practical value. Suitable for safety labels for glass, PVC, polystyrene bottles and glazing cartons.
10. Paper-based partial peel-off label
The base material of the label is coated paper (special paper can also be used), and it is printed with gravure, letterpress and offset. Just uncover the upper part, and the bottom layer will have data for consumers to enter and query. The label is not reusable. When used as a seal, it is firmly attached and not easy to fall off.
11. Regular disclosure compound anti-counterfeiting label
It is a self-adhesive anti-counterfeit label. When in use, the label is directly attached to the product; when it is recognized, the label is uncovered, and a pre-designed invisible graphic and positive image will be left on the package; the invisible graphic and negative image will be removed on the label. Materials such as holographic film, coated paper, and plastic film can be used as the surface material.
