At present, there are more than a dozen types of commonly used anti-counterfeit labels for packaging:
1. Anti-explosion seal
An exposed self-adhesive anti-counterfeit seal with a substrate as a plastic film is a colored non-stick plastic strip before being lifted; after being lifted, a colored writing can be seen on the paper, and an obvious visible on the plastic strip The colorless handwriting has the characteristics of revealing damage, loss and instantness, and is mostly used in the fields of anti-counterfeit envelopes and electrical warranty labels.
2. Fragile paper label
Use special fragile paper or fragile self-adhesive material, which can be printed with trademarks, captions and barcodes. After being attached to the package, it can no longer be completely removed. Once it is lifted, the paper will be broken.
3. Comprehensive anti-counterfeit anti-indentation indentation paper label
The self-adhesive paper label produced by the combination of various anti-counterfeiting technologies can enhance the anti-counterfeiting function. In order to prevent the label from being lifted, replaced and reused, the die-cutting and indentation technology can be used to prevent the label from being partially removed.
4. Barcode technology label
At present, there are many types of bar codes, and the anti-counterfeiting bar codes are mainly one-dimensional bar codes and two-dimensional bar codes. Barcode technology not only promotes better and faster application, but also achieves the goal of not being counterfeited and protecting consumers' interests.
5. Laser holographic image label
The application of laser holographic image technology on anti-counterfeiting packaging is mainly to print anti-counterfeit labels and trademarks. The factors affecting the anti-counterfeiting performance of the laser hologram label are the type and position of the label, and the types of the laser holographic image security label are as follows.
1 self-adhesive type
The holographic anti-counterfeit graphic is made on the self-adhesive material, and it is not necessary to apply any adhesive when used, and the mechanical adaptability is good. The biggest drawback is that it can be used repeatedly, and the criminals can use old packaging and labeling to make fakes.
2 anti-death type
It compensates for the shortcomings of ordinary self-adhesive labels. When the label is removed from the package, the holographic image of the label is completely unrecognizable and cannot be used again, which can prevent the use of the old label to prevent fraud.
3 hot stamping type
It is a kind of holographic anti-counterfeit label that can't be uncovered. It uses a bronzing machine to stamp the holographic anti-counterfeit label onto the packaging material and integrate it with it.
6. Font anti-counterfeit polyester film label
Before the film was lifted, there was no adhesive strip for aluminum foil. After the lifting, there were obvious colored marks on the label paper and packaging materials.
7. Transparent PVC typeface anti-explosion universal label
It is a white, self-adhesive film label before it is lifted. After it is lifted, it has obvious colored marks on the label and packaging materials.
8. Transparent PVC security label
On the self-adhesive label or other documents, the transparent laser holographic film with personalized information does not affect the overall design and original effect, and adds anti-counterfeiting function to make the label personalized.
9. Foam film label
It is a unique semi-gloss white film made up of two layers of polystyrene film. The surface layer is a transparent film suitable for printing; the lower layer is a puffed white foam film. Use a permanent acrylic adhesive. It has a good security and anti-counterfeiting effect. When the label is attached to the substrate and then lifted up, the two layers of film are separated, the label is torn, and the residue of the foam layer remains on the package and is difficult to remove. It is suitable for use in humid environments, especially in the production and packaging of beverages, dairy products, etc., with extraordinary practical value. Suitable for safety labels in glass, PVC, polystyrene bottles and glazing cartons.
10. Paper-based partial uncovering label
The label substrate is coated paper (special paper can also be used), with gravure, letterpress and offset printing. Just uncover the upper part and the bottom layer will have data for the consumer to enter the query. This label cannot be reused. When it is used as a seal, it is firmly attached and does not fall off easily.
11. Rule disclosure composite security label
It is a self-adhesive security label. When in use, the label is directly attached to the product; when identifying, the label is uncovered, and a pre-designed invisible graphic positive image is left on the packaging; the uncovered label has an invisible graphic negative image. A material such as a hologram film, a coated paper, and a plastic film can be used as the face material.
