Description

 Fresh or fruit product laser marking method and product thereof  

The invention relates to a fresh or fruit product laser-marking method and a product thereof, in particular to a fresh agricultural, forestry, fishery and animal husbandry laser marking method and a product thereof Or by-product [by-product].

Regarding the laser marking technology of conventional products, for example, a new type of laser marking 〝 formed on an object after the Republic of China Patent Publication No. M328334 discloses a laser marking formed on the object. The object is an electronic product, and the laser mark comprises a plurality of laser light-forming marking units, and the plurality of laser-light-forming marking units are patternedly formed on the surface of the object. Each of the laser light-forming marking units is a closed-loop annular pocket.

In the above-mentioned No. M328334, the plurality of laser light-forming marking units in the laser marking are arranged at intervals, or the plurality of laser-shaped marking units are arranged in series, and the plurality of laser-shaped marking units in the series are one A continuous curve, and the continuous curve continues to form the shape of a plurality of closed loop-shaped recesses.

In fact, the aforementioned laser light-forming marking unit of No. M328334 is only suitable for forming on the electronic product, so the marking units of the plurality of laser light forming are obviously not suitable for various fresh agricultural, forestry, fishery and animal husbandry products. Laser marking is formed directly on the surface.

Another conventional product laser marking technique, for example, the Republic of China Patent Publication No. 158626, the laser marking method, the invention patent, discloses a laser marking method. The laser marking method uses a laser beam to quickly print a sharp mark on the surface of an object, and the laser marking method prevents the temperature of the surface of the article from rising and reduces the temperature when marking the surface of the object. The laser power required for the beam is emitted, and the distinctive mark has a plurality of colors, making the vivid mark easy to distinguish.

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

In fact, the laser marking method of the aforementioned No. 158626 requires that the pigment layer be preliminarily disposed on the surface of the article, and the surface of the applicable article of the laser marking method is an electronic product surface, so the laser marking method is obviously not It is suitable for laser marking directly on various fresh agricultural, forestry, fishery and animal husbandry products.

Another conventional product laser marking technique, for example, the laser marking of the patent document of the Republic of China Patent Publication No. 200628329, discloses a laser marking formed on an object. Applying at least one printing ink or printing ink layer system to a substrate, and the printing ink or the printing ink layer system comprises at least one layer of laser light sensitive component, and selectively removing the printing ink with a laser light Or printing ink layer systems. In micro-imprinting/images, laser light is simultaneously generated in a selectively removed portion.

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

In fact, the laser marking of the aforementioned No. 200628329 requires that the printing ink layer be preliminarily disposed on the surface of the object, and the printing ink layer must contain a laser light sensitive component, so the laser marking method is obviously not applicable to various Laser marking is directly formed on fresh agricultural, forestry, fishery and animal husbandry products.
