Description
Technical field
The invention belongs to field of anti-counterfeit technology, relate to a kind of false proof blocking film, particularly relate to a kind of false proof blocking film with 3D effect and preparation method thereof.
Background technology
At present, holographic anti-counterfeiting hot stamping film is widely used in packaging field, and relative to traditional printing technology, holographic anti-counterfeiting hot stamping film is lucuriant in design and have innervation, and has certain anti-counterfeiting power.But, along with the develop rapidly of packaging industry, and the generally use of holographic false proof series products, the single anti-counterfeiting power with the conventional photographic blocking film of holographic false proof function declines gradually.
Opal film is also Fei Nier lens coating or 3D cold lamination film, is a kind of novel decorative packaging material.Opal film is a kind of optical lens array imaging film, and lucuriant in design, third dimension is strong, transparency is high, there is lens wide-angle effect image and there is certain anti-counterfeiting power, can broaden one's vision, several image reduced can be observed, because of the extremely similar opal of viewing effect, therefore claim opal film.But because the application mode of opal film is composite membrane, namely adhere to applicating medium (as paper) surface by glue, plastic film layers cannot be removed, and does not meet the environmental requirement of increasingly stringent, cannot be applicable to the packaging such as tobacco bale, the cosmetics of super quality.
The general structure of current false proof blocking film is: PET film, release layer, imaging layer, metallic reflector and glue-line; Wherein, anti-counterfeiting information is produced on imaging layer.Imaging layer is generally thermoplastic coating, uses the mode of hot pressing to be transferred on imaging layer by the anti-counterfeiting microstructure on masterplate, thus realizes the batch duplicating of anti-counterfeiting information.Thermoplastic coating layer thickness is only 0.5 ~ 2um, and very difficult complete copy has the dark texture structure masterplate of 3D effect, and stereoeffect is also difficult to show.Therefore, traditional material, process system cannot realize stronger 3D effect on blocking film.
Adopt the mode of UV mold pressing can fast, batch duplicating goes out the better dark grain pattern of 3D effect, but, under current technology, also be there is following difficult point in blocking film in UV coatings applications: (1) is due to the toughness of UV coating, during for blocking film, the trimming of UV coating is very poor; (2) peel value due to general blocking film is very low, during UV mold pressing, the UV coating after solidification and the adhesion of masterplate often relatively large, there is the problem of sticky version, successfully cannot complete UV mould pressing process on mould release membrance.
Summary of the invention
The present invention is intended to the deficiency that will solve above-mentioned background technology, a kind of false proof blocking film with 3D effect is provided, UV mould pressing process is incorporated in the production process of blocking film, and avoid UV coating trimming difference and the problem of version is glued in UV mold pressing, false proof blocking film realizes 3D effect, both meet the feature of environmental protection requirement of product, greatly promote again visual impact sense and the security feature of anti-counterfeiting mark.
