Description

Printing half-penetration type holographic film

The utility model belongs to the anti-counterfeiting label pad pasting that printing packaging is used, particularly printing half-penetration type holographic film.

Hologram has been widely used on all kinds of anti-counterfeit printings packing, and wherein behaving most, what know is the anti-fake holographic labeling.In recent years along with the cut-throat competition of commodity market, again anti-counterfeiting technology is used on the wrappage, utilize holographic technique to make certain picture and text and add that ink printing wrapping paper, film had both played effect attractive in appearance, play the effect of anti-counterfeiting mark again, and be false proof on the whole packing; What also have is applied in hologram aspects such as certificate, fabrication, as being embedded with the hologram of a fineness with anti-counterfeiting in certain parts such as the credit card of making, driver's licenses.

Making the most economical method of holographic film is with the very thin sheet metal that has hologram image, exert pressure by heating the required picture and text that duplicate are transferred on the required impression materials, plastic sheeting is because it cheap and the characteristics that are easy to moulding often are selected as impression materials.Present holographic goods (particularly anti-fake label) overwhelming majority utilizes gold or silver color plastic opaque film such as PET, PVC etc.Opaque hologram can not be seen the content that hologram pattern covers below, is used on the anti-false wittness card, occupy the sub-fraction position of card card; As printed apcksging material, it is dull that its metallic luster seems, this makes that its use in holographic field is limited to.Therefore, if holographic film can have certain transparency, can be necessary as overlay film.Recently begin the printed matter that the surface is covered with the hyaline membrane of the holographic laser raster pattern that glimmering to occur on the market, as the outer packing box of VCD, but when the useful hand of this product is cleaned grating pattern, because the shortcoming that sweat stain on hand or oil stain disappear hologram pattern.

Fundamental purpose of the present utility model is to provide a kind of printing of not having metallic luster with semi-transparent Ming Dynasty style holographic film, is applied on the overlay film of fabrication, certificate and printed matter, makes the card card or the whole space of a whole page of printed matter all can have holographic pattern and not influence attractive in appearance that card blocks; Another purpose of the present utility model is to see through clear color, literal and the pattern of seeing witness card or printed matter of holographic pattern energy that does not have metallic luster, and can be because of the sweat stain of being with on hand, the disappearance that oil stain causes holographic effect.

The technical solution of the utility model is: the half-penetration type holographic film comprises the labeling body layer and the embossed layer of hologram image or literal is provided; it is characterized in that: on the plastic sheeting surface of transparent body layer 1, scribble layer of transparent embossed layer 3; on the surface of transparent embossed layer 3, be coated with the nonmetal reflection enhancement Layer 4 of one deck, on the surface of nonmetal reflection enhancement Layer 4, scribble the organic transparent protective seam 5 that one deck shields.

The utility model also scribbles organic enhancement Layer 2 that one deck plays bonding effect between the plastic sheeting of transparent body layer 1 surface and transparent embossed layer 3.

Transparency body layer 1, pliability higher by intensity and fastness transparent material preferably constitutes, and does this type of material with plastic sheetings such as PET, PVC, OPP usually; Enhancement Layer 2 is the adhesion height with transparent body layer 1, again with the also high organic coating of transparent embossed layer 3 adhesions, as acrylic compounds and rubber-like coating, when transparent embossed layer 3 itself just had good adhesion with transparent body layer 1, this enhancement Layer shouldn't; Transparency embossed layer 3 is one deck organic coatings that are used to provide hologram, and this coating is often selected the coating of polyesters, acrylic compounds, by hot pressing holographic grating is transferred on this layer from masterplate; Nonmetal reflection enhancement Layer 4 is by technology such as sputters the oxide of one deck high index of refraction to be covered in the surface of embossed layer 3, and as monox, titanium dioxide, zirconia or the like, it can strengthen the effect of hologram; Transparency protective seam 5 is the high and good coatings of wearing quality of layer of transparent degree, is used to protect hologram not to be worn, polyurethane generally commonly used, modifying epoxy resin by organosilicon, acrylate etc.

The utility model can be with transparent body layer 1 according to printing ink on the printed matter and compound the selection with bonding agent, or protective finish 5 covers mutually with the printed matter face when concrete the application, is combined to guarantee overlay film and product, is difficult for peeling off.

Holographic grating of the present utility model is protected in labeling film inside, and outside two sides is matcoveredn all, and it is very convenient to be used on printed matter, the certificates such as card card etc., and no matter tow sides can be compound with affixed object spare for it; Owing to adopt the protective seam of transparent material as labeling; so; see through labeling and can not only see the content of printing on the printed matter clearly, can also see the hologram that does not have metallic luster of ornamental or antifalsification, and can the filling of holographic grating striped not disappeared because of sweats stain on hand.

Below in conjunction with accompanying drawing the technical solution of the utility model is further described.
