The holographic packaging material of dark line lens of large format and numerical digit
Technical field
The utility model relates to dark line lens of large format and the holographic packaging material of numerical digit.
Background technology
Though the laser anti-counterfeiting packaging material are used widely, anti-antifalsification is not strong.For effectively stopping spreading of fake wine market, be badly in need of a kind of high technology content holographic packaging material simultaneously attractive in appearance again that possess.
Dark line lens are a kind of a kind of technology that under the former device subsidiary conditions of optics, adopt mechanical engraving; Be characterized in that the strong curvature of third dimension is big; Be commonly called as opal as a three-dimensional sphere, but because it is dark line technology, the PET film that routine has the 2U thick coating can't impress its stereoeffect of demonstration; Generally can only be presented on does not need coating directly on the PE and PVC material of mold pressing, has limited its utilization field at packaging material.And the holographic packaging material of the dark line lens of large format and numerical digit are a kind of packaging material new technologies that dark line lens technologies and numerical digit holographic technique are combined; It will can only be realized on the PET material in the mode of the dark line lens that could realize on PE or the PVC through the UV pigment transfer in the past; And combine with the numerical digit holography, opened up the packaging market field greatly, because its technical matters difficulty is big; The batch process stability requirement is high, so possessed higher security feature.
Summary of the invention
To the problems referred to above, the utility model is combined in dark line lens and numerical digit holographic laser version on the same laser plate, and the combination precision reaches 0.01mm, and combination place perusal does not have hollow out and leaks silver, reaches advanced world standards.In addition, the utility model also adopts the UV coating process, has changed the coating press moulding mode of traditional holographic packing, carries out mold pressing with low-temp low-pressure power mode, and prolongation laser plate service life cuts down the consumption of energy.The 3rd, dark line lens are used on the PET packaging material and with the numerical digit holography appear simultaneously first, strengthened the antifalsification of material.
In order to realize the foregoing invention purpose, the utility model discloses the holographic packaging material of dark line lens of large format and numerical digit, it is characterized in that comprise: a coating, said coating are aqueous coating: a PET film, said coating are arranged on the said PET film; One UV coating is coated under the said PET film; One aluminium lamination, aluminium coated below said UV coating; A compound glue of one water-based and a paper, said aluminium lamination and said paper are through the compound glue bonding of said water-based.
Reasonablely be, said PET film thickness is 15-20U, the about 7-15u of said UV coating, and said aluminium lamination is a 0.03-0.05mm thickness.
The utility model is broken through original dark line lens can only show the limitation on the PE material, through the UV coating process it can be presented on the PET material simultaneously with the numerical digit holography, has strengthened the versatility of its packaging field.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, from the detailed description to the utility model, above-mentioned and other purposes of the utility model, feature and advantage will be obvious.
Fig. 1 is the decomposing schematic representation of the utility model.
The specific embodiment
See also Fig. 1, the utility model comprises coating 1, is generally water-based, surface tension 42 dyne; Through adhering to the PET film 2 of processing especially, its thickness is 15-20U, UV coating 3; About 7-15u thickness, be equivalent to about 10 the gram/square metre, have dark line lens sum digit hologram pattern on it; Aluminium lamination 4, common 0.03-0.05mm thickness, compound glue 5 of water-based and paper 6.
The making step of the holographic packaging material of dark line lens of the large format of said structure and numerical digit is following:
The first, the PET film is through adhering to processing;
The second, PET film coated UV coating parallel machine laser molding; The radium-shine coating of tradition is a thermoplastic resin, heat drying, rolling after the cable roll coating.And then through mold pressing procedure.And the UV+ laser molding all-in-one of the utility model, online realization.Film after UV coating, first uviol lamp partial desiccation (do not flow but not absolutely dry).Pass through the laser molding roller then, laser pattern is stamped on the coating, solidify dry again through ultra violet lamp.
The 3rd, radium-shine face is aluminized;
The 4th, aluminize face and paper are through the glue compoiste adhering;
The 5th, PET pellicular front coating aqueous coating, to adapt to road, back printing demand, this coating surface tension force reaches 42 dyne.
The utility model is broken through original dark line lens can only show the limitation on the PE material, through the UV coating process it can be presented on the PET material simultaneously with the numerical digit holography, has strengthened the versatility of its packaging field.
More than all embodiment only supply to explain the usefulness of the utility model; But not to the restriction of the utility model; The technical staff in relevant technologies field; Under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or variation, so the category that all technical schemes that are equal to also should belong to the utility model should be limited each claim.
