The Authenticity Detection Techniques of Tamper Evdient Tape

Tamper evident tape is a widely employed anti-counterfeiting material, commonly used in packing, sealing, marking, and other applications. To ensure the authenticity of anti-counterfeit tape, various testing techniques are employed to verify its authenticity. The following section introduces several common techniques used for detecting the authenticity of anti-counterfeit tape.

Appearance observation method
Appearance observation method is the simplest and most commonly used anti-counterfeit tape authenticity detection technology. By observing the appearance of anti-counterfeit tape, you can initially determine its authenticity.

Color Observation: The true color of the anti-counterfeit tape should be stable, uniform, without color differences, and free from a sense of glare.

Gloss Observation: The gloss of genuine anti-counterfeit tape may vary. Please note that the higher the transparency of the anti-counterfeit tape, the clearer the text or pattern within the tape.

Printing Quality Observation: Fonts and patterns on the anti-counterfeit tape should be clear and colorful. In the case of high counterfeit products, there is often a risk of blurring and color mismatch in the details.

Texture observation: The texture of real anti-counterfeit tape is even and regular, while the texture of counterfeit products may be irregular.

Second, destructive testing method
Destructive detection method is a kind of detection technology to judge the authenticity of anti-counterfeit tape by destructive means.

Burning method: take a small piece of anti-counterfeiting tape and burn it. The real anti-counterfeiting tape should not burn easily and have no dripping phenomenon when burning. While the counterfeit products may burn fast, with dripping or short burning time.

Strong peeling method: Use special tools to peel off the anti-counterfeit tape from the affixed object. Genuine anti-counterfeit tape should have high peeling strength, while counterfeit products may be easy to peel off.

Tearing method: the real anti-counterfeit tape should have high tearing strength, and the edge of the tape should be flat when it is torn, while the fake products may not be neatly torn.

Spectral analysis
Spectral analysis method is a technique to detect the authenticity of anti-counterfeit tape through spectrometer.

Visible Spectrum Identification: The reflectance curve of genuine anti-counterfeit tape in the visible spectrum range will have certain characteristics. By placing the anti-counterfeit tape in the spectrometer, the visible spectral reflectance curve can be obtained and compared with the genuine product.

Infrared Spectrum Identification: The characteristics of the infrared light reflected by the genuine tape will also be different. By placing the anti-counterfeiting tape in the infrared spectrometer, you can get its infrared spectral characteristics and compare it with the real product.

Physical property test method

Physical property testing method is a technique to judge the authenticity of anti-counterfeit tape by measuring its physical properties.

Strength test: the tensile strength of genuine anti-counterfeit adhesive tape should be higher, while the tensile strength of counterfeit products may be lower.

adhesion test: genuine anti-counterfeit tape should have better adhesion performance, while counterfeit products may have certain problems in adhesion.

weathering test: genuine anti-counterfeit tapes have different weathering properties. By placing the anti-counterfeit tape in a specific environment for testing, you can understand its weathering performance and compare it with the real product.

It should be noted that the above testing methods are not used individually, and it is usually necessary to combine various testing methods for authentication to enhance accuracy. At the same time, for products that require a high degree of anti-counterfeiting, advanced technologies, such as microlight imaging, infrared imaging, laser engraving, etc., can also be applied to improve the anti-counterfeiting effect.
