Description
Technical field
The invention belongs to packing articles fields, and in particular to one kind takes off aobvious holographic color printing anti false film and preparation method thereof.
Background technique
Hologram image has the characteristics that image clearly, lucuriant in design, three-dimensional sense is strong, just extensive from the eighties in last century
Applied to packaging field, the awake destination locations of surface of package are generally all disposed within, now with laser hologram image manufacturing technology
With popularizing for equipment, imitation technology is also being constantly progressive, and the anti-counterfeiting performance of hologram image also becomes poor, does not adapt to mesh
Preceding anti-fake needs.
Summary of the invention
The surface that anti false film is arranged in it is an object of the invention to solve prior art hologram image, it is poor that there are anti-counterfeiting performances
Defect, one kind is provided and takes off aobvious holographic color printing anti false film and preparation method thereof, hologram image is hidden in the inside of anti false film,
Transfer coated using adhesive tape lifting cleaved surface can just be seen, anti-counterfeiting performance is greatly improved.
The present invention is achieved by the following technical solution:
I.e. one kind takes off aobvious holographic color printing anti false film, it is characterised in that including PET basement membrane, color-printed layer, composite coating, complete
Cease Information Level and transfer coated, the composite coating and it is transfer coated between bonding force be less than color-printed layer and composite coating
Between bonding force.
Holographic information layer of the invention is to form rough holographic lines on composite coating by contour forging, is applied
After cloth is transfer coated, holographic lines is filled and led up, to conceal holographic information.
The firmness requirements of bonding force between color-printed layer and composite coating of the invention are the bigger the better, theoretically not
Allow to peel away, composite coating and it is transfer coated between have peeling effect, bonding force is much smaller, when using external force (it is preferential but
It is not limited to using adhesive tape) to open transfer coated, this product can just show holographic laser effect.
A kind of production method for taking off aobvious holographic color printing anti false film of the present invention, it is characterised in that steps are as follows:

Transfer coatings of the invention are solvent type transfer coatings, are mainly characterized by: coating levelability and good film-forming property, transparent
Degree is high, has good stripping performance, is controlled by adjusting each component ratio, the especially ratio of adjusting methyl methacrylate
The peeling force of coating processed, is conducive to technology controlling and process.Most importantly transfer coatings are different painting Materials from composite coining coating
System, does not interfere with each other mutually in process, ensures the independence of respective coating performance.
The effect of each raw material is as follows in transfer coatings of the invention:
Cellulose ethanoate: coating host agent, film-forming resin enhance the film forming of coating；
Methyl methacrylate: controlling the transfer performance of coating, ensures transfer coated fissility.
DOP: plasticizer
Butanone, butyl acetate: solvent
Further, the production method of composite coining coating of the invention are as follows: deionized water, alcohol, butyl
It requires to be mixed in proportion, be then divided into two parts according to 2: 1 ratio, one large solvent is slowly added to aqueous under stirring
Acrylic resin then proceedes to stir, and mixing time is greater than 30min；Alkyd-propylene is slowly added under aliquot stirring solvent state
Acid copolymer then proceedes to stir, and mixing time is greater than 30min；After the completion of stirring, two parts of resin solutions are mixed, and
Dipropylene glycol methyl ether is added under stirring, mixing time is greater than 30min, and stirring is completed, and composite coating is made.
Further, transfer coated production method of the invention are as follows: butanone and butyl acetate are mixed in a reservoir
It closes, then mixed solvent is divided into two parts, a copy of it is slowly added to acetyl cellulose under stirring and is dissolved, and stirs
The time is mixed greater than 30min, another solvent is slowly added to methyl methacrylate under stirring and is dissolved, mixing time
Greater than 30min, being mixed after the completion of two parts of solution stirrings, and DOP is added under stirring, mixing time is greater than 30min,
Stirring is completed, and transfer coating is made.
Further, 80-130 DEG C of coating temperature of transfer coating of the invention, is coated with drying time 5-10S.
Color-printed layer of the invention prints various decorative patterns, text, trade mark, enterprise logo etc..
Composite coating and PET base membrane layer of the invention and printing layer are tightly combined, securely.
Holographic information layer of the invention can be general-purpose version or special edition when being molded.
It is of the invention it is transfer coated there is removability, can be separated with composite coating, it is transfer coated under normal condition
By the holographic information layer covering on composite coating, after transfer coated removing, holographic information layer can just be shown on composite coating
Come.
When the present invention is opened using adhesive tape: applying but be not limited to the pressure sensitive adhesive tape of 4cm wide (pressure sensitive adhesive tape bonding force is strong and one
Cause property is good) it is fitted in transfer coated surface, adhesive tape then is opened from adhesive tape one end in 90 degree, at this moment transfer coated and adhesive tape one
It rises and strips down, removing position holographic laser pattern displays.
Anti false film of the invention applies also in paper plastic combined package, and film first passes through above-mentioned processing, to make to pack
Information is presented on film, and packing box is formed after paper-plastic stick, and after packing box destroys, film is separated with paper destructiveness, transfer
Coating is stripped, to show holographic effect, has outstanding and intuitive line anti-counterfeiting performance.
Product of the invention has the advantages that anti-counterfeiting performance is good, and production method of the invention has process stabilizing reliably excellent
Point.
1) composite coating of the invention from it is transfer coated be made of different systems coating, will not shadow when being coated with transfer coated
It rings on composite coating and composite coating the performance of holographic information layer and appearance is transfer coated smoothly to turn from composite coating
Shifting is got off, and process stabilizing is reliable.
2) product common color printing effect only simple in terms of appearance, these information are disclosed.But in film
Inside implies holographic information layer, and holographic information layer can be the various holographic information security patterns such as product information, company LOGO
And text, these information will not be seen under normal circumstances, only take off it is transfer coated after can just display, play very
Practical and effective antifalse effect.
