Abstract

The utility model relates to an unlocking membrane with an anti-counterfeiting function, which comprises a printing membrane and a plurality of unlocking structures positioned on the printing membrane. The unlocking structures at equal intervals are parallelly arranged on the printing membrane and formed by ink on the printing membrane by means of transfer printing through a screen printing plate, and screen wires matched with unlocking patterns on an outer package of a product are arranged on the screen printing plate. The unlocking membrane with the anti-counterfeiting function resolves the technical problems which cannot be resolved by a traditional unlocking card, practicality of the unlocking anti-counterfeiting technology is greatly enhanced, counterfeits are effectively controlled, and manufacturers and customers can be benefited in deed.

Description

A kind of have an anti-fraud functional release film

Technical field

The utility model relates to a kind of release film, relates in particular to a kind of anti-fraud functional release film that has.

Background technology

The release anti-counterfeiting technology is at present domestic more advanced, a kind of anti-counterfeiting technology that use cost is lower.Particularly, it belongs to an anti-counterfeiting technology in plate-making field, and the similar version of antifalse effect line is false proof, has very strong non-reproduction, needs when reading " separating locking plate ".

The key of release anti-counterfeiting technology is in the inner security element that embeds of packages printing pattern, when observing, normal vision can't see the security element of embedding at all, have only special configuration " separating locking plate " as for the embedding position of security element and adjust respective angles, could know the security element of seeing embedding.

The release anti-counterfeiting technology is to adopt principle of interference, promptly allows the texture of separating locking plate identical with the frequency of anti-counterfeiting image shading, can't see the image or the Word message of embedding like this under the situation of not separating locking plate fully.Mode of composition that it should be noted that security element constitutes by lines.The release anti-counterfeiting technology is finished when plate-making, in press represents, and does not increase extra printing cost, and unrestricted on the selection material, the making form is very extensive.

Traditional to separate locking plate false proof, and practicality is relatively poor, because most consumers can not differentiate and carry the release card because of buying some product in real life.So real actual effect is not played in the application of release anti-counterfeiting technology.

The utility model content

The utility model is not easy to the consumer and differentiates at the existing locking plate of separating, and makes the application of release anti-counterfeiting technology not play the deficiency of real actual effect, and a kind of anti-fraud functional release film that has is provided.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of have anti-fraud functional release film and comprise the film of undertaking the printing of, be positioned at a plurality of unlocking structures on the described film of undertaking the printing of, described a plurality of unlocking structure equidistantly and in parallel to each other is arranged on the film of undertaking the printing of, described a plurality of unlocking structure forms the printing ink transfer printing by the gauze forme on the film of undertaking the printing of, have on the described gauze forme with product external packaging on the netting twine that is complementary of release pattern.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, the thickness of the described film of undertaking the printing of is 1 micron～30 microns.

Further, described unlocking structure is the list structure with mound shape projection.

Further, the xsect of described mound shape projection is circular-arc, and described circular-arc height is 6 microns～10 microns, and the ratio of distance is 0.18～0.63 between the width of described unlocking structure and adjacent two unlocking structures.

Further, the xsect of described mound shape projection is rectangular, and the ratio of distance is 0.11～0.75 between the width of described unlocking structure and adjacent two unlocking structures.

The beneficial effects of the utility model are: the utlity model has anti-fraud functional release film and solved the insurmountable technical matters of traditional release card, make release anti-counterfeiting technology practicality strengthen greatly, false product is effectively controlled, manufacturer and consumer really are benefited.

Embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.

Embodiment 1

Shown in Fig. 1 and 2, described have anti-fraud functional release film and comprise the film 11 of undertaking the printing of, be positioned at a plurality of unlocking structures 12 on the described film 11 of undertaking the printing of, described a plurality of unlocking structure 12 equidistantly and in parallel to each other is arranged on the film 11 of undertaking the printing of, described a plurality of unlocking structure 12 forms the printing ink transfer printing by the gauze forme on the film 11 of undertaking the printing of, have on the described gauze forme with product external packaging on the netting twine that is complementary of release pattern.The thickness of the described film 11 of undertaking the printing of is 1 micron～30 microns.The list structure of described unlocking structure 12 for having mound shape projection.The xsect of described mound shape projection is circular-arc, and described circular-arc height H is 6 microns～10 microns, and the ratio of distance L 2 is 0.18～0.63 between the width L1 of described unlocking structure and adjacent two unlocking structures.In the present embodiment, described printing ink is foam ink, the transparent foam ink of special type is printed on the outsourcing damp-proof membrane of packaging products such as cigarette-brand, wine mark, and through UV foaming and oven dry, foam ink just forms the parallel convex line texture of specific rule on the damp-proof membrane surface.Then the release film is wrapped in by the package and production technique requirement on the packaging products such as cigarette-brand, wine mark, damp-proof membrane is put angle must make its surperficial convex line texture consistent with anti-counterfeiting information grain direction on the packing material.Because after the transparent foam ink foaming still is transparent, so this die can not influence the packaging product visual effect, but, can make the anti-counterfeiting information image of embedding interfere with it and display because of the concavo-convex lines on the die to containing the pattern of unlock image part.After the consumer buys product, tear the damp-proof membrane on surface, the anti-counterfeiting information image that embeds on the packing can disappear.In addition, the consumer can not tear damp-proof membrane, only needs damp-proof membrane is passed away from the package body surface, and the anti-counterfeiting information image also can disappear or thicken.

Embodiment 2

Shown in Fig. 3 and 4, undertake the printing of the list structure of unlocking structure 22 on the film 21 for having mound shape projection, difference from Example 1 is that the xsect of mound shape projection is rectangular, and the ratio of distance L 2 is 0.11～0.75 between the width L1 of described unlocking structure and adjacent two unlocking structures.In the present embodiment, described printing ink is common colored ink, and described colored ink line of ink marker die is identical with transparent concavo-convex line die principle, and just line of ink marker width parameter value changes to some extent, and its weak point is because the line of ink marker has color.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
