Embodiment 1

[0030] Such as figure 1 As shown, the laser marking film in this embodiment is composed of a composite film structure layer, and the composite film structure layer includes a first transparent composite layer 140, a laser marking layer 130, a second transparent composite layer 150, a cover layer 120 and a third transparent composite layer. Transparent composite layer 110 .

[0031] The laser marking layer 130 in the laser marking film 100 can provide excellent laser marking effects, and can permanently mark text and patterns with high definition and contrast under the irradiation of laser beams of different intensities, and play a significant role in security and anti-counterfeiting ; The upper surface of the laser marking layer 130 is co-extruded with a first transparent composite layer 140, and the first transparent composite layer 140 can protect the internal structure layer well, while providing excellent thermal composite molding properties, to meet the needs of thermal ...

Embodiment 2

[0045] Such as figure 2 As shown, the laser marking film in this embodiment is composed of a composite film structure layer, which includes a first transparent composite layer 140 , a laser marking layer 130 , a second transparent composite layer 150 and a cover layer 120 .

[0046] The feature of this embodiment is that one layer of third transparent composite layer 110 is added on the basis of Embodiment 1, which can further simplify the processing technology and cost, but the effect of laser marking will not be affected, and it can also meet the requirements of use. Other parts of this embodiment And the functions and effects are the same as in Embodiment 1, so the description will not be repeated.

Embodiment 3

[0048] Such as image 3 As shown, the laser marking film in this embodiment is composed of a composite film structure layer, which includes a laser marking layer 130 , a second transparent composite layer 150 , a cover layer 120 and a third transparent composite layer 110 .

[0049] The feature of this embodiment is that one layer of the first transparent composite layer 140 is reduced on the basis of Embodiment 1, the lower surface of the laser marking layer 130 is the second transparent composite layer 150, and the other side of the second transparent composite layer 150 is a cover Layer 120 , the lower surface of the cover layer 120 is the third transparent composite layer 110 .

[0050] The characteristics are the same as that of Embodiment 2. The reduction of one layer of transparent composite layer can further simplify the processing technology and cost, but the effect of laser marking will not be affected, and it can also meet the requirements of use. Other parts of thi...

Abstract

The invention relates to a laser marking film. The laser marking film comprises a composite film structural layer, wherein the composite film structural layer comprises a laser marking layer; and the invention further provides components of the composite film structural layer. The laser marking film provided by one or more embodiments of the invention can be permanently marked to form a text and a pattern with high definitions and contrasts, so that a safe anti-fake function is obtained; meanwhile, an excellent light shielding property and a thermal composite molding property can be provided to satisfy thermal composite bonding and molding requirements between different materials.Besides as a good light shielding property is provided, a very good shielding and protective effect is obtained on the internal composing structure, and the safety is further improved; therefore, the laser marking film provided by the invention can be widely applied to data information pages in government confidential documents, identity cards and passports, ID cards, credit cards, insurance cards, driving licenses, various identification cards and the like, as well as other places where safe anti-fake functions are needed.

Description

technical field [0001] Embodiments of the present invention relate to a film, in particular to a laser marked film. Background technique [0002] At present, the traditional printing and marking technology usually prints the required characters and patterns on the surface of the product. During long-term use, it is easy to fall off, fade, wear and damage, the safety is not high, and the anti-counterfeiting effect is not good. The process will cause environmental pollution and affect people's health; on the other hand, since the ink printed on the surface of the product is easy to contaminate the mold during the processing process, it will affect the quality and yield of the processed product and increase the cost. [0003] Laser has attracted widespread attention since its birth, and its highly directional and high energy density characteristics make it widely used in ranging, cutting, drilling, marking and other aspects. Among them, laser marking technology is of great sig...
