Description
Technical field
The present invention relates to anti-fake protective film field, in particular to a kind of laser anti-counterfeiting film.
Background technique
Laser anti-counterfeiting glazing tacky film is mainly used in label industry, can be used for the anti-fake protection of various product label, tool
There is the features such as good, beautiful, environmentally friendly, the resistance to ink of antifalsification corrodes, barrier steam and carbon dioxide ability is high.Domestic and international market is to radium
Penetrating anti-fake glazing tacky film has a certain amount of demand, however there are no the laser anti-counterfeiting glazing gluings of direct gluing on the market at present
Film product, laser anti-counterfeiting film used in label is pre-coating film or adhesive-free film in the market, there is the interim gluing overlay film of user or hot pressing patch
It closes, low efficiency and energy consumption height, for interim gluing coating technique, because environmental protection is strictly just gradually being eliminated increasingly.Therefore, urgently
A kind of laser anti-counterfeiting glazing tacky film that can be used directly need to be developed.
Summary of the invention
It is an object of the invention in view of the above shortcomings of the prior art, provide a kind of BOPP laser anti-counterfeiting glazing gluing
Film, while the preparation method of the BOPP laser anti-counterfeiting glazing tacky film being provided.
The technical solution used in the present invention is: a kind of BOPP laser anti-counterfeiting glazing tacky film, from top to bottom by BOPP
Base membrane layer, resin medium layer, water-borne pressure sensitive adhesive adhesion coating composition, BOPP base membrane layer lower surface is equipped with radium-shine embossing.
Specifically, the resin medium layer is the intermediate bridge for improving BOPP base membrane layer and water-borne pressure sensitive adhesive adhesion coating, can
The water-borne pressure sensitive adhesive adhesion coating when BOPP laser anti-counterfeiting glazing tacky film uncoiling is set not remove resin medium layer, to reach
It can directly wind, the purpose of uncoiling.
As a further improvement of the foregoing solution, the resin medium layer is coated by bottom coating resin, the primary coat tree
Rouge is mixed with by polyketone resin, neutral polyamide resin, maleficent acid resin, organic solvent and ethyl acetate.
As a further improvement of the foregoing solution, the preparation method of the bottom coating resin is first with condensing reflux equipment
Being added in closed container by raw material weight ratio is (5~8): the organic solvent and ethyl acetate of (2~5), is then added and presses raw material
Weight ratio is (32~35): (38~42): polyketone resin, neutral polyamide resin and the maleficent acid resin of (20~25),
It is stirred and is heated to being completely dissolved, cooling, control viscosity is 4500~6500CPS.Specifically, bottom coating resin of the present invention
Viscosity is moderate, and subsequent filming performance after drying is good, has moderate pliability and wetting index, not only can effectively protect radium
Penetrate embossing, and its binding force for sticking layer with water-borne pressure sensitive adhesive is good.
As a further improvement of the foregoing solution, the resin medium layer with a thickness of 3~5 μm, further make BOPP
There is moderate binding force between base membrane layer and water-borne pressure sensitive adhesive adhesion coating.
As a further improvement of the foregoing solution, the BOPP base membrane layer with a thickness of 21~25 μm.
As a further improvement of the foregoing solution, the depth of the radium-shine embossing is 2~3 μm, is not influencing BOPP base
Assign the BOPP laser anti-counterfeiting glazing tacky film excellent laser effect on the basis of film layer and resin medium layer.
As a further improvement of the foregoing solution, the BOPP base membrane layer is from top to bottom by surface layer, middle layer and bottom group
It is melt index >=3.8g/10min high transparent resin layer at, the surface layer, the middle layer is melt index 3.0~
Polypropylene resin layer within the scope of 3.8g/10min, the bottom are that melt index is poly- within the scope of 2.5~3.0g/10min
Allyl resin layer.
As a further improvement of the foregoing solution, the surface layer with a thickness of 1~2 μm, the middle layer with a thickness of 18
~20 μm, the bottom with a thickness of 2~3 μm.Wherein the restriction of skin depth advantageously reduces the attached of aqueous pressure sensitive adhesive layer
Put forth effort, so that the BOPP laser anti-counterfeiting glazing tacky film be made to reduce deflection when carrying out uncoiling.
As a further improvement of the foregoing solution, the surface layer by propylene-ethylene-vinyl acetate ter-polymer resin or
Propylene-ethylene block copolymer resin composition.
Another technical solution adopted by the present invention is: a kind of BOPP laser anti-counterfeiting glazing tacky film as described above
Preparation method comprising following processing step:
1) control die head temperature is 260~270 DEG C and carries out melting co-extrusion, through curtain coating, sharp cooling roll quenching treatment, 165~
3~5 times of longitudinal stretching, 5~8 times of cross directional stretch are carried out in 175 DEG C of insulating boxs, obtain BOPP base membrane layer；
2) BOPP base membrane layer lower surface coats bottom coating resin after radium-shine embossed, and drying obtains resin medium layer；
3) water-borne pressure sensitive adhesive stick is coated in resin medium layer lower surface, drying forms water-borne pressure sensitive adhesive adhesion coating, directly receives
Roll up to obtain finished product.
Specifically, the appropriateness crystallization of the longitudinal stretching multiple and transverse stretch ratio defined conducive to macromolecular chain,
To greatly improve the tensile strength of the BOPP base membrane layer, to be conducive to the stability and durability of radium-shine embossing, effectively mention
The high overlay film performance of the BOPP laser anti-counterfeiting glazing tacky film.
The beneficial effects of the present invention are:
BOPP laser anti-counterfeiting glazing tacky film of the invention can directly be used for label overlay film after uncoiling, with marking after overlay film
The advantages that alice is not wrinkle resistant, laser effect is clear, overlay film is high-efficient, easy to use, environmentally friendly is signed, is overcome used in conventional labels
Laser anti-counterfeiting film is the defect of pre-coating film or adhesive-free film.
Preparation method operating process controllability of the invention is strong, is conducive to large-scale industrial production, is prepared into
BOPP laser anti-counterfeiting glazing tacky film has excellent overlay film performance, and viscous force is good, uncoiling power is light, and can directly carry out overlay film makes
