Abstract

The utility model relates to a laser holographical anti-counterfeit aluminum foil, which is characterized in that aluminum foil is used as base material, a layer of imageable optical information resin is coated on the aluminum foil surface to form an information layer; an image layer is arranged on the information layer. The utility model has the advantages of high efficiency of image diffraction, large width extension, tiny seam, no overlap of pattern, good abradability, good anti-counterfeit effect and low production cost.

Description

Antiforge laser holographic aluminium foil

The utility model relates to a kind of packings such as medicine, cosmetics and food that are applied to the anti-fake aluminium-foil on soft bag or blister package, bottled seal etc., relates in particular to a kind of antiforge laser holographic aluminium foil.

Present domestic Packaging Aluminum Foil, its surperficial picture and text pattern is to adopt traditional common printed mode to process, technology is rough, therefore, the sharpness of picture and text pattern is relatively poor, can not the variable color with the variation of visual angle, and there is not special metallic luster flicker effect, product texture is coarse, dim, no antiforge function, and the incompatibility modern packaging is with the demand of aluminum foil material development.Because of aluminium foil belongs to hard metal material, international like product is to adopt common laser holographic imaging principle, directly in the aluminium foil surface laser imaging, major defect is in hard machine mode: the plate-making breadth is narrower, and wide usually is about 150mm, if add wide format, then need with the mode of artificial splicing the polylith version to be stitched together, therefore, many versions that vertically have of picture and text pattern are stitched, and version seam broad stitches wide to more than the 0.3mm; Laterally an edition seam pattern is located continuously, and pattern has overlapping or the big phenomenon in slit, and version is stitched or pattern overlapping is wide reaches more than the 1mm, so the picture and text pattern effect is poor, the image diffraction efficiency is low, and the serviceable life of every width of cloth version is shorter; Processing aluminium foil linear meter is a 500-1000 rice only, so cost of products is higher.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of image diffraction efficiency height is provided, and breadth is roomy, the version seam is superfine, and the pattern zero lap has good wearing quality, antifalse effect is preferable, the antiforge laser holographic aluminium foil that production cost is lower.

Design proposal of the present utility model is as follows:

A kind of antiforge laser holographic aluminium foil comprises aluminium foil 1 and image layer 3, and its special character is: the carried Information Level 2 that described aluminium foil 1 surface-coated has the imageable optical information resin of one deck to constitute, described image layer 3 is arranged at can carry on the Information Level 2.

But the deposited metal 4 of above-mentioned image layer 3 surface spraying plating layer of metal or nonmetallic materials.

Above-mentioned deposited metal 4 surfaces can apply layer protective layer 5.

Above-mentioned Information Level 2 thickness that carry are advisable with 2 μ m.

The utility model compared with prior art has following advantage:

1. the utility model is base material with the normal aluminium foil, can carry laser imaging on the Information Level, adopts the seamless spliced wide cut plate-making of computer control;

2. breadth is roomy, and breadth has improved nearly ten times than prior art, can reach 1100-1200mm;

3. laterally version seam picture and text pattern is located continuously, and the version seam is superfine, only is 0.10mm, and the pattern-free overlapping phenomenon;

4. every width of cloth version can be processed aluminium foil linear meter 50000-60000 rice, has improved production efficiency greatly, has reduced cost of products;

5. have high gloss retention, the optical effect of picture and text pattern is had the better protect effect, product has good wearing quality, adapts to the technological requirement of aluminium foil subsequent handling fully;

6. have special optical effect, image diffraction efficiency height, optical characteristics is easy to identification, and not only having can be with the effect of visual angle variable color, and has special metallic luster flicker effect;

7. the utility model can design and produce out different two dimensions or three-dimensional plot texts and pictures case according to user's requirement, and as enterprise trademark, character image etc., anti-counterfeiting characteristic is obvious, and is difficult for copying, and antifalse effect is preferable.

Accompanying drawing is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to accompanying drawing, the utility model applies one deck imageable optical information resin on aluminium foil 1 surface with coating machine as base material with aluminium foil 1, the about 2 μ m of coating thickness, and formation can be carried Information Level 2; The imageable optical information resin of coating can be carried Information Level 2 oven dry; Method with laser hologram is made the laser version, can carry laser imaging on the Information Level 2 with the mode of soft machine, forms image layer 3, about about 160 ℃ of working temperature; Also the vacuum available coating machine forms deposited metal 4 in image layer 3 surperficial spraying plating last layer metal or nonmetallic materials, to strengthen the diffraction efficiency and the persistence of image.Also can apply one deck wear resistant resin on deposited metal 4 surfaces and form protective seam 5, to strengthen the wearing quality and the gloss retention of image; At last, rewinding, cut, pack promptly and finish.
