Description

Thin solid 3D Grating Films

Technical field

The utility model is related to printed apcksging material technical field, and in particular to a kind of thin solid 3D Grating Films.

Background technology

Slim 3D 3 D gratings film is, into grating line number, to utilize grating using grating vision software different pattern transformations The principle of refraction, different pattern anti-fake films are showed in different angles.In China, stereoscopic picture plane and the design for becoming picture face Manufacturing technology is just increasingly mature, in the application stereoscopic imaging technologies such as advertisement, wedding photo, indoor and outdoor decoration, printing, grating material Material plays very important effect.Traditional 3 D grating film must be directly printed in grating using the thicker shape Grating Film of thickness The back side of film is made, and not only thickness is thicker, and stereoeffect is not obvious.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of thin solid 3D gratings for above-mentioned prior art Film, while grating film thickness is reduced, improves stereoeffect.

The technical scheme in the invention for solving the above technical problem is：A kind of thin solid 3D Grating Films, it includes The grating information layer that from bottom to top the PET basement membranes of stratification, microballon structure sheaf and use UV materials are made successively, the microballon structure Layer is made up of diffusion layer, PET intermediate layers and resist blocking and that layer, and diffusion layer and resist blocking and that layer are applied in the middle of PET by way of coating The front and back of layer, the diffusion layer surface, which has in the micropore that multiple apertures are 0.01-0.03 microns, each micropore, adulterates There is particulate as scattering particles, doped with particulate as scattering particles in the resist blocking and that layer, the grating information layer is The semicircle sub-wave length grating of one group of sinusoidal relief type quasi-reflection volume.

Preferably, the corrugation pitch of two neighboring semicircle sub-wave length grating is from for 150-200um, the grating information layer It is made up of transparent resin, its refractive index is 1.4~1.9.

Compared with prior art, the utility model has the advantage of：

Slim 3D 3 D gratings film thickness of the present utility model only has 50 microns（0.05mm）, can be applied to packaging market (such as：Cosmetics, drinks, medicine ... etc., print color box), Label Markets, postcard, monthly calendar, member card or vip card, books and newspapers it is miscellaneous The front cover of will, is more widely applied.Its unique 3D 3-D effect can increase the value and antiforge function of product.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of microballon structure sheaf in the utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

Such as Fig. 1, shown in 2, the utility model is related to a kind of thin solid 3D Grating Films, including from bottom to top stratification successively PET basement membranes 1, microballon structure sheaf 2 and the grating information layer 3 being made of UV materials, the microballon structure sheaf 2 by diffusion layer 2.1, PET intermediate layers 2.2 and resist blocking and that layer 2.3 are constituted, and diffusion layer 2.1 and resist blocking and that layer 2.3 are applied in the middle of PET by way of coating The front and back of layer 2.2, the diffusion layer 2.1 uses sintrered nickel（Also have using ceramics or polytetrafluoroethylene (PTFE)）It is made, often puts down There are several hundred million micropores on square centimetre of diaphragm, aperture is about 0.01-0.03 microns, doped with particulate 2.1.1 in each micropore As scattering particles, light can be passed through constantly when by diffusion layer in the different medium of 2 refractive indexes, therefore light will Occur many refractions, the phenomenon of reflection and scattering, so just cause in the effect of optics diffusion, the resist blocking and that layer 2.3 Doped with particulate as scattering particles, the grating information layer 3 is sub- for the semicircle of one-dimensional sinusoidal relief type quasi-reflection volume Wave length grating, the corrugation pitch of two neighboring semicircle sub-wave length grating is from for 150-200um, and grating information layer passes through exploitation Cylinder grating mold is made, and the grating information layer is made up of transparent resin, and its refractive index is 1.4~1.9, and the grating is believed Breath layer is formed by nickel mother matrix hot pressing, and the thickness of whole Grating Film only has 0.05mm, is significantly less than conventional thickness thicker（0.15- 2mm）Shape Grating Film.

In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
