How are anti-counterfeiting marks made on packaging bags? What are the key technical points?

Anti-counterfeiting marks are customized anti-counterfeiting products according to customer requirements. At present, with the development of the market trend, there are many counterfeit products. Many well-known brand companies, in order to protect their own and customers' interests, have successively begun to use product anti-counterfeiting marks. Among the many anti-counterfeiting marks, how does the company choose the anti-counterfeiting marks suitable for itself? Shunxingyuan Packaging, a professional flexible packaging manufacturer, believes that you need to first understand the principles of anti-counterfeiting marks and key technical points.

1. Principles of Anti-counterfeiting Marks

A unique number is set for each licensed product, and this number is stored in the base database, and a telephone (mobile phone or Internet) query identification network is established nationwide. Customers who purchase products with digital anti-counterfeiting marks only need to make a phone call, go online, or send a message, enter the number on the product, to understand the authenticity of the product, thus overcoming the limitations of traditional anti-counterfeiting products being easily counterfeited in large quantities and customers being unable to distinguish them.

2. Anti-counterfeiting Mark Technology

1. Laser Holography Technology

After laser plate making, the image is produced on the heat-sealable film, creating a colorful transmission effect, making the image three-dimensional, which is a commonly used anti-counterfeiting technology nowadays. At present, China has launched new holographic anti-counterfeiting technologies such as two-dimensional three-dimensional true color embossed holography, pixel holography, and electro-optical code holography.

2. Fluorescent Material

It appears light-colored or white in sunlight and shows bright colors under ultraviolet light, and can be used in a variety of anti-counterfeiting technologies. Its fluorescence intensity is high, and the printing adaptability is good.

3. Watermark Paper

This kind of paper uses online forming technology in the production process to produce various special mark watermark pictures. Under general backlight irradiation, the watermark pictures are shown. Watermark paper is widely used in the anti-counterfeiting printing of currency, securities and certificates.

4. Anti-counterfeiting Ink

Special printing ink made by adding special functional anti-counterfeiting materials to printing ink and processed by special technology. At present, there are: fluorescent ink, magnetic printing ink, anti-smear printing ink, photosensitive printing ink, thermistor printing ink, etc. Ultraviolet fluorescent ink is used. Thermistor printing ink is used in the temperature control anti-counterfeiting mark of the thermal reaction equation. When used, the anti-counterfeiting color fades slightly when the mark is heated, showing the manufacturer's anti-counterfeiting mark, and after cooling, the anti-counterfeiting color is restored, and the anti-counterfeiting mark is covered again.

5. Anti-counterfeiting Thread Technology

A metal wire or plastic wire is placed in the center of the paper during the papermaking process, which can be small English letters, fluorescence, etc. Its shapes include parallel lines, wavy lines, and sawtooth lines. The Chinese RMB paper also uses parallel anti-counterfeiting lines.

6. Double-sided Printing Technology

Through professional printing technology, the same painting on both sides of a certain position of the security is completely consistent. This technology has high requirements on the precision of plate making and printing.

7. Barcode Technology

Barcodes include metal barcodes and invisible barcodes. Metal barcodes are high-tech products that integrate coding technology, computer technology, laser technology, and information security anti-counterfeiting technology. Special identification instruments are required for identification. Invisible barcodes add some hidden marks when making barcode plates.

8. Electric Code Anti-counterfeiting Mark Technology

A secret code is set on each product, and all product secret codes are recorded in the anti-counterfeiting center database. Customers only need to use a phone, a computer, or other items that can connect to the anti-counterfeiting network to enter the product secret code to carry out anti-counterfeiting verification and distinguish the authenticity of the product. Because the secret code of this technology is randomly generated by the computer, it is processed immediately after the query, and it cannot be counterfeited, and the relative cost is low. It is an effective anti-counterfeiting technology at that time. China Mobile phone and other access certificates have adopted this electric code anti-counterfeiting technology.

In various product labels encountered in our daily life, the designs of anti-counterfeiting marks are different, but they often have common functions. Anti-counterfeiting mark designers will customize them according to product characteristics and enterprise needs. Therefore, no matter what, as consumers, we not only need to ensure the safety of our products, but also save our purchase costs.

3. Anti-counterfeiting Marks

What are anti-counterfeiting marks? Anti-counterfeiting marks (labels) are anti-counterfeiting certifications made by product manufacturers for their own products. This certification uses the principle of one product, one code, just like everyone's ID card. During product circulation, consumers can check the manufacturer's information and product details through digital anti-counterfeiting queries. Anti-counterfeiting labels protect manufacturers' products from being counterfeited and help consumers quickly check the authenticity of products.
