Abstract
The invention discloses a laser anti-counterfeiting aluminum foil and its preparation method. The anti-counterfeiting aluminum foil contains a delomorphic aluminum plating layer, an adhesive layer and a metal aluminum foil layer overlapping successively. The preparation method mainly contains washing, gluing, heating, pressing, covering membrane, water or wind cooling and removing membrane etc. of the aluminum foil. The invention transfers the laser anti-counterfeiting membrane onto the aluminum foil by using new-type BOPP. The BOPP substrate membrane has good temperature and age resistance, soft materials, without coating transparent shape-separating layer and simple technology. Transferring the anti-counterfeiting membrane onto the aluminum foil can avoid the laser patterns disappearing or destroying. The whole membrane has good temperature resistance and is uneasy to craze. The invention can be applied in many fields such as packing bag and building materials etc. It has extensive application range and good market value.
Description
[technical field]
The present invention relates to anti-fake aluminium-foil, relate in particular to laser anti-fake aluminium-foil.
[background technology]
Laser anti-counterfeiting is light wave amplitude of vibration information and corresponding information to be noted simultaneously in the extremely short time with LASER Light Source, with every millimeter thousands of interference bar code, utilizes the interference of light principle, reflects each particle of composing images, i.e. laser holographic figure.After being made into version, can't producing duplicate plate with same preparation method again, thereby reach false proof purpose.
Present laser anti-counterfeiting transfer membrane all is to adopt the PET transfer membrane.The PET transfer membrane be on the PET base material film, coat earlier transparent in the shape layer, then in the transparent layer of transparent embossed plies that on the shape layer, is coated with again, utilize transparent embossed plies on moulding press, to carry out mold pressing, rough different pattern is just arranged on the embossed plies after the mold pressing, and then on rete, carry out vacuum aluminum-coated, thereby produce the laser anti-counterfeiting transfer membrane.PET base material film in this transfer membrane is a carrier, though have temperature tolerance preferably, promptly do not shrink about 200 ℃, resistance to ag(e)ing, but its material is harder, and radium-shine layer is changed places and the PET base material film is peeled off, just must on the PETT base material film, be coated with layer of transparent from the shape layer earlier, make complexity of technical process.
Present laser anti-counterfeiting film all is directly to transfer on the tinplate.On the face of aluminizing, coat earlier adhesive sticker, transfer on the tinplate laser tinplate through after the oven for drying.Need to stretch because a system jar industry is made cover, the laser pattern of punching press place is with regard to evanescence or destroyed behind the punch ram; The temperature tolerance of laser anti-counterfeiting film does not reach requirement, tinplate all needs through printing when being used as the system jar, present printing all is to adopt heat fixed type ink, printing must be toasted at least 18 minutes/look in the baking oven about 190 ℃-220 ℃, and transparently can not bear high-temperature baking so for a long time from shape layer and embossed plies at all, under this temperature, can ftracture, can not satisfy user's needs at all, also can address this problem at present without any technical scheme.
So, how to adopt the material that is more suitable for, the technology of more simplifying to produce the important topic that high-quality laser anti-counterfeiting film becomes our research.
[summary of the invention]
Purpose of the present invention solves the problems of the prior art exactly, proposes a kind of laser anti-fake aluminium-foil and manufacture method thereof, adopts new material, and quality is good, and technology is simple.
For achieving the above object, the present invention proposes a kind of laser anti-fake aluminium-foil, comprise the superimposed successively aluminium coated of showing one's color, adhesive phase and metal aluminum foil layer.
As preferably, also comprise protective clear layer, described protective clear layer is superimposed is showing one's color above the aluminium coated.
As preferably, also comprise outer transparent plastic layer and interior clarity plastic layer, described outer transparent plastic lamination be combined in the aluminium coated of showing one's color above, described in clarity plastic layer superimposed below the metal aluminum foil layer.
For achieving the above object, the invention allows for a kind of manufacture method of laser anti-fake aluminium-foil, comprise the steps:
Aluminium foil cleans: the surface to the metal aluminum foil raw material is cleaned;
Gluing: apply glue at the aluminium foil upper surface that cleans up;
The baking of heating: the aluminium foil body after the gluing is sent into the baking oven baking of heating, after uniform temperature, take out;
The multiple film of pressurization: adopt the warm-up mill pressurization that the BOPP transfer membrane is compound on the coated face of aluminium foil body, the base membrane layer on the compound tense BOPP transfer membrane outwardly;
Water-cooled or air-cooled: directly cooling or employing water cooled rolls cool off composite bed naturally;
Take off film: the BOPP basement membrane on the cooled composite membrane is taken off, obtained laser anti-fake aluminium-foil.
As preferably, after taking off film, also comprise composite protection layer: on the pressurization of showing one's color above the aluminium coated is compound protective clear layer or showing one's color above the aluminium coated simultaneously and below the metal aluminum foil layer compound on clarity plastic layer.
As preferably, after taking off film, also comprise and drench the film cooling: the plastic liquid of fusing is drenched the two sides of laser anti-fake aluminium-foil, form inside and outside clarity plastic layer after cooling.
Beneficial effect of the present invention: the present invention adopts novel BOPP transfer membrane that the laser anti-counterfeiting film is transferred to aluminium foil, and the BOPP base material film has temperature tolerance and resistance to ag(e)ing preferably, and material is softer, does not also need to be coated with transparent in the shape layer, and technical process is simple; Anti false film is transferred on the aluminium foil, laser pattern can not disappeared also be not easy destroyed, the resistance to elevated temperatures of whole film is good, can not ftracture; The present invention can be used in a plurality of fields such as packaging bag, building materials,, range of application is very extensive, has good market value.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
