Description

Product packaging laser marking method and product packaging

The present invention relates to a product packaging (package) laser marking (laser-marking) method and product packaging; in particular, to a product packaging anti-counterfeit (anti-counterfeit) laser marking method and product packaging.

Regarding conventional product laser marking technology, for example, the new patent of "Laser Mark Formed on Object" in Patent Publication No. M328334 of the Republic of China discloses a laser mark formed on an object. The object is an electronic product, and the laser marking includes a plurality of marking units formed by laser light, and the plurality of marking units formed by laser light are formed on the surface of the object in a patterned distribution. Each of the marking units formed by the laser light is respectively a ring-shaped cavity with a closed curve.

In the above-mentioned laser marking No. M328334, several marking units formed by laser light are arranged at intervals, or the marking units formed by laser light are arranged in series, and the marking units formed by laser light in series are one A continuous curve, and the continuous curve forms the shape of several closed ring-shaped concavities.

In fact, the above-mentioned several laser-shaped marking units of No. M328334 are only suitable for forming on the electronic product. Therefore, these several laser-shaped marking units are obviously not suitable for directly forming laser marking on various product packages. .

Another conventional product laser marking technology, such as the invention patent of "Laser Marking Method" in Patent Publication No. 158626 of the Republic of China, discloses a laser marking method. The laser marking method utilizes a laser beam to quickly print a distinct mark on the surface of an object, and when marking the surface of the object, the laser marking method can prevent the temperature of the surface of the object from rising, and reduce the laser The laser power required to irradiate the beam, and the bright mark has a variety of colors, so that the bright mark is easy to identify.

The surface of the aforementioned article No. 158626 is covered with a pigment layer, and when a predetermined temperature or higher, the color of the pigment layer changes from a primary color to another color. The pigment layer is provided with a pattern according to the shape of the desired mark, and the laser beam is irradiated on the pattern to print a mark of the desired color.

In fact, the laser marking method of the aforementioned No. 158626 requires the pigment layer to be pre-disposed on the surface of the article, and the surface of the article applicable to the laser marking method is the surface of an electronic product, so the laser marking method is obviously not It is suitable for laser marking directly on various product packaging.

Another conventional product laser marking technology, such as the invention patent application of "Laser Marking of Valuable Documents" in Patent Publication No. 200628329 of the Republic of China, discloses a laser marking formed on an object. Coating at least one printing ink or printing ink layer system onto a substrate, and the printing ink or printing ink layer system comprising at least one layer of laser light sensitive components, and utilizing a laser light to selectively remove the printing ink or printing ink layer system. At the time of micro-imprinting/imaging, the laser light is simultaneously generated in a selective removal site.

The substrate of the aforementioned No. 200628329 includes paper, cardboard, board, plastic, plastic film or laminate. In addition, the laser light-sensitive component includes various laser light-sensitive materials such as carbon, carbon black, graphite, etc., and the laser light is selected from Nd: YAG laser light, Nd: YVO ₄ laser light, diode laser light or CO ₂ laser light shoot light.

In fact, the laser marking of the aforementioned No. 200628329 requires the printing ink layer to be pre-arranged on the surface of the object, and the printing ink layer must contain laser light-sensitive components, so the laser marking method is obviously not applicable to various Laser marking is directly formed on the product packaging.
