Description

Double anti-counterfeiting film

Technical Field

The utility model relates to an anti-fake membrane, especially have 3D dynamic display and radium-shine demonstration anti-fake membrane product concurrently simultaneously.

Background

The Beijing printing institute yellow school Master notes in his Master's academic paper that: with the rapid development of economic science and technology, market competition becomes more and more intense, so that counterfeit and shoddy products frequently grow. The certificate card ticket, various hot-sale commodity trademarks, marks, packages and the like are counterfeited in a dispute, a consumer often spends a large amount of money but purchases fake commodities, and the loss to manufacturers and the loss of the country are caused in the face of wide complaints of the consumer and counterfeiting of the brand of the consumer; the current counterfeiter approach is more and more advanced, which is also a serious challenge for manufacturers and anti-counterfeiting industries. The commodity anti-counterfeiting has the characteristics of magic height and high height, and the anti-counterfeiting capability of any anti-counterfeiting technology is gradually weakened along with the increase of application time. The market continuously demands anti-counterfeiting technologies with novel characteristics, and the dynamic and naked eye three-dimensional display anti-counterfeiting technology is one of the technologies with novel anti-counterfeiting functions.

Wherein, the U.S. adopted the microlens anti-fake technique in 2010 on the safety line of its new edition 100 dollar paper money, adopted the microlens technique, made anti-fake label information "100" and "free clock" can alternate each other, had dynamic effect, had promoted anti-fake effect greatly.

However, with the further improvement of market demand, the single dynamic anti-counterfeiting can not meet the requirements of customers, and the market urgently needs to enable the anti-counterfeiting film to have more anti-counterfeiting characteristics on the basis of dynamic anti-counterfeiting.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dual anti-fake membrane, to the single problem of above-mentioned anti-fake effect, through the packaging structure who improves anti-fake lens membrane, introduce radium-shine packaging effect at low refracting index resin encapsulation layer, realize two kinds of anti-fake effects on a product, existing optics dynamic effect also has the colorful illusion-colour effect of colour, strengthens anti-fake characteristic of anti-fake membrane.

In order to achieve the purpose, the utility model provides a double anti-counterfeiting film which is characterized in that the anti-counterfeiting film and the packaging layer are respectively a micro-lens anti-counterfeiting film and a packaging layer from bottom to top;

the packaging layer is positioned on the spherical mirror side of the micro-lens anti-counterfeiting film, is combined with the spherical mirror and forms a packaging plane on the top of the spherical mirror;

and laser grains are arranged on the outer surface of the packaging layer.

As a further improvement, the anti-counterfeiting film is an image-text layer, a substrate layer and a lens layer from bottom to top respectively.

As a further improvement of the present invention, the refractive index of the encapsulation layer is not more than 1.5.

As a further improvement of the utility model, the surface of the outer surface laser lines of the packaging layer is provided with a transparent coating layer.

The utility model adopts the low refractive index UV resin packaging layer which is necessary for matching with a plurality of later processes (IMD/IMR/compounding, etc.); meanwhile, the laser effect is introduced into the packaging layer, so that the problem of single anti-counterfeiting effect can be solved, no additional process is added, two anti-counterfeiting effects are realized on one product, and the optical dynamic effect and the colorful fantasy effect are realized.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The utility model discloses a when dual anti-fake membrane used, as shown in figure 1, observe in dual anti-fake membrane 1's front by the people's eye, can see the picture and text of enlargeing.

The specific structure of the double anti-counterfeiting film 1 is shown in fig. 2, and the image-text layer 11, the base material layer 12, the lens layer 13 and the packaging layer 14 are respectively arranged from bottom to top; wherein, the outer surface of the packaging layer 14 is provided with laser lines 15.

The utility model discloses a during preparation of dual anti-fake membrane, mainly include following step:

step 1: coating a microlens array structure on one surface of a transparent substrate layer 12 such as PET (polyethylene terephthalate) by using a UV (ultraviolet) forming process to form a lens layer 13, and coating a corresponding micro image-text array structure on the other surface of the transparent substrate layer to form an image-text layer 11; forming a microlens film;

step 2: packaging the spherical lens surface of the micro-lens film generated in the step 1 to form a packaging layer 14; in the packaging process, a laser texture die is adopted to emboss the outer surface of the packaging layer 14 to form laser texture 15.

In the conventional packaging process, a mirror surface mold is adopted for packaging, the surface of the packaging layer 14 is flat, and only the 3D dynamic effect of the dynamic film can be observed; and it is right the surface of encapsulated layer 14 is processed into radium-shine line 15, then introduces radium-shine effect, makes the utility model discloses a dual anti-fake membrane 1 both had dynamic effect, had the light and become the effect again, had solved single anti-fake problem.

If the follow-up IMD/IMR/compound technology of the product is needed, the laser texture surface needs to be coated, and the transparent coating is generally formed by vacuum evaporation of zinc sulfide (ZnS).

The specific requirements of the materials of each layer are as follows:

1. an image-text layer 11; the material is as follows: UV resin, thickness: >2 microns;

2. a base material layer 12; the material is as follows: optical grade PET, thickness: 12-300 microns;

3. a lens layer 13; the material is as follows: UV resin, thickness: 5-200 microns;

4. an encapsulation layer 14; the material is as follows: low refractive index UV resin, thickness: 2-100 microns (higher than the thickness of the top surface of the sphere of the lens layer 13);

the refractive index of the UV resin with the low refractive index is less than or equal to 1.5; the refractive index after curing is generally 0.1-0.2 higher than that before curing;

the refractive index of the encapsulating resin depends on the microlens diameter, the product thickness and the lens resin refractive index, i.e. the thickness of the focal plane image.

5. Laser lines 15; pressing and forming the surface of the packaging layer 14 by adopting a laser texture mould;

6. total thickness of the film product: 30-500 microns.

Packaged products tend to be 3 times thicker than direct display products.
