Description
Technical field
The present invention relates to the changeable visual angle of a kind of partial holography and lens stereoscope aluminium paper, the invention still further relates to the manufacture method of the changeable visual angle of this partial holography and lens stereoscope aluminium paper, belong to field of packaging material.
Background technology
Paper is as a kind of environment-friendly materials, be widely used in all kinds of packaging product, but along with the diversification of product, people's improving constantly for esthetic requirement, simple art post paperboard packaging can not meet the demand of client, and plastics package, mental package do not meet the Packaging Development trend of environmental protection, so a kind of novel packaging material---holographic packaging materials arises at the historic moment in recent years.Holographic packaging materials is that laser holography is made into holographic mother by photograph or Computing mode by one, a kind of packaging material made after again holographic mother being carried out mold pressing, its advantage is that the hologram pattern on packaging material is made up of interference fringe, penetrate generation diffraction by illumination again and present the effect of seven coloured silks, comparatively traditional paper packaging is abundanter has more metallic luster simultaneously, and the parent being more and more subject to consumer and manufacturing enterprise at present looks at.In the market by packaging material mainly two classes that holographic technique makes, a class is holographic false proof label, and another kind of is holographic universaling packing.The former has the advantage that precision is high, antifalsification is strong, but makes the little complex process of area, so can only be used on some labels; The latter's precision is low, pattern is abundant, size is large and be easy to produce, but holographic unicity is strong easily imitated, so it is lower to manufacture threshold.
Holographic changeable visual angle refers to holographic lithography, by changing the change such as width, density, interference frequencies of interference fringe, causes the visual effect of hologram pattern different angles.Lens stereoscope refers to use holographic lithography, is adopted that the one of arc lithography simulation Fresnel Lenses is coaxial, off-axis gaussian beam lens by the mode of vector photoetching.Aluminium paper comprises aluminium-plated laminating paper and aluminium-plated transfer paper and refers to directly at PET or BOPP film or have in the PET film of hologram pattern, by vacuum aluminium-plated by aluminium molecule accumulation on film, finally by glue by film and paper compound, what directly use after compound belongs to aluminium-plated laminating paper, and what compound rear film was peeled off belongs to aluminium-plated transfer paper.
Existing product has following weak point:
The first, because opal lens are formed by smart steel stone lathe machining, requirement on machining accuracy is high, and the saturating degree of opal is determined by Processing Curve radian, is processed into power low cost high.
The second, because opal lens are that dark line machining is formed, need by UV group version mode with laser holographic combinations of patterns, location group version precision can produce deviation, affects final packaging material positioning precision, brings difficulty to printing chromatography.
Three, the opal lens lines due to machining formation is dark, reaches about 10 μm, and common coating method cannot realize transfer, UV coating method can only be passed through, car scooter 110 ms/min is produced in common coating, and UV coating only has 30 ms/min, and production efficiency is low.
Four, common coating transfer coatings, coating weight only has 1 ~ 1.4g, and opal lens lines is dark, and reach about 7 ~ 8 μm, can only pass through UV coating method, coating weight reaches 10g, and cost is very high.
Five, be coated with the opal of mold pressing again and laser holographic film due to lines by UV too deeply cannot realize shifting, so the mode that film and paper are fitted can only be adopted, because surface has thin film so can not effectively degrade, so do not meet the development trend of packaging material environmental protection.
