Abstract

The utility model belongs to an anti-fake packing technology field and discloses a thermal shrinkage film provided with the anti-fake function, on which the nuclear track micro-hole anti-fake sign is marked to enable the utility model not only with anti-fake function for difficult imitation, but also to be recycled for packing fake.

Description

A kind of have an anti-fraud functional heat shrink films

(1) technical field

The utility model belongs to the package anti-counterfeiting technical field, is specifically related to a kind of anti-fraud functional heat shrink films that has.

(2) background technology

Package anti-counterfeiting can be used for commodity false proof that antifalsification labels are pasted in some inconvenience, and owing to need not paste, use easier than antifalsification label, can also avoid true antifalsification label to be taken off the problem that pastes on the fake products, but general anticounterfeit package is easy to the fake products that is recycled and packaged by the counterfeiter again by intact.

Heat shrink films is very disposable widely packing of a kind of application, itself just can avoid being repeated using, if can have certain antiforge function, then not only can avoid true antifalsification label by the intact problem that pastes on the fake products of taking off, can also avoid general anticounterfeit package to be easy to the be recycled and packaged problem of fake products by the counterfeiter.

Application number is that 00135665 Chinese patent discloses a kind of structure texture anticounterfeit package, mainly be that the coloured foreign material that adhered to some random scatterings on packing material are formed anti-fake mark, this packing material also can be a heat shrink films, its advantage is to be difficult to copy, but the inquiry of need making a phone call or surf the Net when discerning the false from the genuine is cumbersome.

Application number is that 01264039 Chinese patent discloses a kind of shrink wrap with accurate Antiforge, mainly be to adopt the method for trans-printing to print on heat shrink films to establish the laser pattern that one deck is made up of tiny lines or the pattern of aluminizing as anti-fake mark, this false proof heat shrink films ratio is easier to be copied.

Application number is that 01226489 Chinese patent discloses a kind of false proof shrinkable film molding device, it mainly is the problem that is subjected to thermal contraction when having solved heat shrink films mold pressing laser holographic pattern, can produce mold pressing has the heat shrink films of laser holographic pattern anti-fake mark, because the technology of mold pressing laser holographic pattern is very universal, this false proof heat shrink films also relatively is easy to be copied.

(3) utility model content

The purpose of this utility model is: a kind of anti-fraud functional heat shrink films that has is provided, and this heat shrink films not only has antiforge function, and the method for discerning the false from the genuine is easier, also is difficult to copy.

Scheme of the present utility model is: a kind of have an anti-fraud functional heat shrink films, mainly comprises heat shrink films and anti-fake mark, and anti-fake mark is some nuclear-track porous and/or nuclear track pits of heat shrink films itself.Owing to have anti-fake mark on the heat shrink films, so this heat shrink films has antiforge function; Because the discriminating of nuclear-track porous anti-fake mark only needs smearing lipstick, wax crayon, ink or water etc., do not need to inquire by telephone or the internet login inquiry, so it is very easy to discern the false from the genuine; Because making nuclear-track porous nuclear radiation source is national strict control and danger close, high energy acclerator is domestic also to have only one, global quantity also few, make the nuclear-track porous very technical professional that also needs, the counterfeiter is difficult to grasp these materials, equipment, technology and the talent, so this heat shrink films is difficult for being copied.

Major advantage of the present utility model has five: first is to have antiforge function; Second is easier when discerning the false from the genuine; The 3rd is to be difficult for being copied; The 4th is not exist to resemble the antifalsification label by the intact problem that pastes on the fake products of taking off; The 5th is because heat shrink films can only disposablely use, and this have anti-fraud functional heat shrink films and can not reclaimed by the counterfeiter and pack fake products again.

In order to strengthen decorative effect, can also have the mold pressing laser holographic pattern on the heat shrink films.

Heat shrink films can be transparent.

Can also have printed patterns on the heat shrink films.

Heat shrink films can be a coiled material, the certain length in every interval just has one or some nuclear-track porous anti-fake marks on the heat shrink films coiled material, and the heat shrink films coiled material also can the certain distance in every interval just have one or some nuclear-track porous anti-fake marks on Width.

For different anti-counterfeiting object is used different nuclear-track porous anti-fake marks, simultaneously also in order to strengthen antifalse effect, preferably has the pattern of its meaning or/and literal, letter, symbol by some nuclear-track porous anti-fake marks of forming of heat shrink films itself.

(4) description of drawings

Also in conjunction with the accompanying drawings the utility model is provided further instruction below by most preferred embodiment.

Fig. 1 is the schematic perspective view of the utility model embodiment 1;

Fig. 2 is the A-A semi-sictional view enlarged diagram of Fig. 1;

1. heat shrink films among the figure, 2. nuclear-track porous anti-fake mark, 3. nuclear-track porous or nuclear track pit, 4. mold pressing laser holographic pattern.

(5) specific embodiment

Embodiment 1:

Shown in accompanying drawing 1, accompanying drawing 2, present embodiment is a volume heat shrink films coiled material, heat shrink films 1 is the BOPP shrink film, on heat shrink films 1, just has an anti-fake mark 2 with the every interval of Width certain-length along its length, anti-fake mark 2 is by some nuclear-track porous and nuclear track pit 3 is formed pictorial trademark, brand name and the corporate names on the heat shrink films 1, and nuclear-track porous and mean diameter nuclear track pit 3 is 40 μ m; Can adopt the method manufacturing of the nuclear-track porous anti-fake mark of common manufacturing on the heat shrink films 1 by the nuclear-track porous anti-fake mark of forming 3, dry or method that normal temperature dries up and do not adopt the method for heat drying as long as drying process after immersion adopts; The mold pressing laser holographic pattern 4 that on heat shrink films 1, also has some regular distribution.
