Problems solved by technology

However, due to the printing cursor and die-cutting position will always be affected by the accuracy of the equipment and printing accuracy, there will be errors
The protective film used is pasted on the surface of the card body, and it is slightly smaller or just right than the surface. If there is an error, it will be obvious, which will affect its appearance and normal use.

Embodiment 2

[0068] Such as Figure 4 Shown, on the other hand, the present invention provides a kind of manufacture method of making composite film again, wherein: comprise,

[0069] Step S110, providing a base film;

[0070] Step S120, performing composite glue treatment on the first predetermined layer of the base film;

[0071] Step S130, compounding the first predetermined layer of the base film and the second predetermined layer of the protective film and performing drying and curing treatment. After the drying treatment, the composite glue is cured, and the composite glue in the cured state completely composites the first predetermined layer of the base film and the second predetermined layer of the protective film.

[0072] As a further preferred embodiment, the above-mentioned method for making a composite film, wherein step S110, providing a base film specifically includes:

[0073] Step S11011, providing an initial film; wherein the initial film can be a PET / PVC film body, an...

specific Embodiment approach

[0097] Provide a PET base film with a thickness of 20-38um, corona treatment or chemical coating treatment on one side to increase its surface energy or polarity. The other side is coated with a matte coating, and the function of the matte coating is to prevent the film surface from being drawn during the production process.

[0098] Provide a PET protective film: thickness 15-35um, one side of the PET protective film is treated with corona, the other side is free of corona, and the information layer is coated on the corona surface. The information layer is generally acrylic resin or reactive polyurethane resin, and the thickness range : 1.0-2.0um; the optical micro-nano pattern (also can be understood as anti-counterfeiting pattern) is transferred to the film by molding, and a recognizable laser cursor is placed next to the pattern of each plate during molding; then the dielectric layer is evaporated to improve the optical micro-nano The reflectivity of the pattern. Coat the...

Abstract

The invention relates to the technical field of films, in particular to a composite film and a manufacturing method for manufacturing the composite film. The composite film comprises: a base film; a composite connecting layer, which is arranged on the surface of the base film; and a protective film, which is arranged on the surface of the connecting layer, wherein the base film is provided with amark area, and the mark area comprises a mark pattern and a mark hole area matched with the mark pattern. The mark hole area 102 and the protective film 3 are cut by the same cutter, and the sizes ofthe mark hole area 102 and the protective film 3 are completely consistent.

Description

technical field [0001] The invention relates to the technical field of thin films, in particular to a composite film and a method for making the composite film. Background technique [0002] Card-type certificate heat transfer film can usually be applied to size card-type certificates, bank cards, and certificate production points, such as Hong Kong and Macau passports, Taiwan compatriots certificates, etc. Specifically, the card body carrying personalized information is passed through a special card transfer device Composite heating with the heat transfer film of the card-type certificate, then peel off the base material, transfer the transparent optical anti-counterfeiting information layer directly on the card body, and then compound a new protective film on the card body, the optical anti-counterfeiting layer is exactly the same size as the card surface , very consistent, beautiful, can not completely peel off the covered anti-counterfeiting information layer, and play a...
