The application of one-time anti-counterfeiting technology of commodity packaging

one-time packaging anti-counterfeiting technology refers to the use of commodity packaging anti-counterfeiting. There are two main cases of packaging anti-counterfeiting. One is a disposable packaging, which is damaged once opened and cannot be used again; The other is not only disposable packaging, but also with anti-counterfeiting marks or anti-counterfeiting information on the packaging. In the first case, we can only ensure that the goods in the package are not replaced, but generally we can't guarantee that the goods in the package are genuine in three steps, unless this kind of packaging can't be imitated at all. In the second case, if we can ensure that the anti-counterfeiting logo cannot be copied and the packaging is not a variety of bags, we can not only ensure that the goods in the packaging are not replaced, but also ensure that the goods in the packaging are genuine

generally speaking, a real anti-counterfeiting package must ensure that the goods in the package are not exchanged, and that the goods in the package are genuine

there are many packages belonging to the first type, such as various disposable cartons and cartons sealed with strong scotch tape. Once the tape is uncovered, the paper surface at and around the original cover will be damaged, and it is generally unrecoverable. If you seal with scotch tape again, these damage traces will be seen. If you seal with opaque tape again, you will violate the anti-counterfeiting instructions because it is not scotch tape. Another example is that some wine bottles that have to be broken to pour out wine are invalid and can no longer be restored. Therefore, as long as the bottle mouth is intact, the wine in it must not be replaced. Cans also belong to this kind of packaging

it should be pointed out that not all disposable packaging can prevent the items in it from being replaced. For example, containers such as cups and boxes sealed with plastic film, although opening will damage the plastic film, it will not damage the container itself, and can still be repacked to make the heavenly clothes seamless. Another example is the sealed container welded with steel plate or plastic plate, which can be welded and sealed again after cutting, and then the weld can be polished and restored as before

there are also many types of the second type, such as cartons with cross stitched anti-counterfeiting marks on each seal, or bottles with the same anti-counterfeiting mark on the bottle body and cap. If this anti-counterfeiting mark cannot be forged at all, and it cannot be opened or removed intact at all, then it is certain that the items in it have not been replaced, and it can generally be determined to be genuine, but it cannot be absolutely guaranteed to be genuine, Because counterfeiters may also obtain anti-counterfeiting marks through theft, bribery, bribery and other means. So far, the packaging anti-counterfeiting technology that can really meet these conditions has not been applied

at present, there are some packaging products that claim to have anti-counterfeiting function in the market, and their anti-counterfeiting performance is mostly unreliable. For example, there is a kind of image and text vanishing tape. Its principle is that the cross-section of the tape is composed of a release agent layer, a transparent plastic film, a low viscosity ink printing layer and an adhesive layer from top to bottom. Because the base film of the tape is transparent, the special image and text seal can be displayed after the original sealing of the tape. Because the bonding strength between the interface layers is different, the image and text mark disappears automatically after being unpacked. If it is re sealed, there will be no image and text mark. In addition, there is an optical fiber seal. This technology is to add an optical fiber to the packaging seal. After the package is pasted with this seal, if it is unsealed without authorization, the optical fiber in the seal will move in the wrong position, and the light diffraction stripes in the wrong position can be seen only with a flashlight or facing the bright light. There is also a plastic film packaging seal, which is a new material developed by the American optical coating test center and PA and other technology companies. The material is a plastic film that will change color under the action of external force, and the film is coated with reflective interference coatings of different wavelengths. Under normal circumstances, the coating is bright. Once used, the coating begins to peel off, the film turns gray, and the peeled part will also produce patterns. In fact, the anti-counterfeiting functions of these three kinds of tapes are very limited, because they are not difficult to be imitated. As long as the counterfeiter has this kind of tape, he can reseal it after opening it, and even does not need to reseal it. He can imitate a large number of packaging boxes as long as it is encapsulated with this kind of tape. 3. People who have nothing to do with the operation of the electronic universal experimental machine are not allowed to operate the experimental machine. To say the least, even if these tapes cannot be imitated, how can we take the microcomputer closed-loop control to ensure that the counterfeiters will not obtain them through theft, bribery and other means? Safety valves can be added to protect the sensor. In addition, there are some packages such as "anti-theft bottle caps", "non refillable caps", "vacuum type visible and stealthy caps", and their anti-counterfeiting functions are also very limited, because these technologies are open, and the counterfeiters are easy to master. Although the real packaging containers are difficult to reuse, it is not difficult to imitate this kind of packaging

conclusion: disposable packaging anti-counterfeiting technology, which has a wide variety and belongs to auxiliary anti-counterfeiting means, is mainly against the counterfeiting behavior of individual businesses who recycle old packaging. There is a certain market. Generally, it is used together with anti-counterfeiting products with anti-counterfeiting marks
