Abstract

The utility model provides a novel anti-counterfeiting packing film which is a colorless transparent plastic film on which concave convex impressions of diverse depths imprinted by a metal plate purpose-made by laser hologram are arranged, and the concave convex impressions are corresponding to patterns and literals. Two-dimensional, three-dimensional dynamic or static patterns, the patterns and the literals or the literals with very strong stereo perception and trenchant levels are reproduced under white light. The utility model has very high anti-counterfeiting character, the utility model can be used for packing production lines of commodity automation, and excellent decorative effects and anti-counterfeiting effects are especially provided to famous cigarettes, famous wines and medicines.

Description

The antifalse packaging film

The utility model relates to a kind of packaging film, particularly relates to a kind of antifalse packaging film.

People are at commodity at present, and the false proof aspect of strengthening famous-brand and high-quality goods such as product as tobacco and wine, food, medicine, change generally adopts the antiforge laser holographic mark, as anti-false trademark, labeling etc.Generally be that this anti-fake mark is sticked in the commodity packaging in use, or adopt heat-transferring method, transfer printing is on the packing of commodity.Need to paste one by one or transfer printing, speed is slow, and efficient is low, especially can not satisfy the automatic packaging manufacturing line, as the needs of high speed packaging production lines such as cigarette, wine, medicine.The aspect has the exquisite colored printing of some commodity for its packing of protection now in addition, makes it seem more magnificent, generally all packs one deck colourless transparent plastic film in external packing again.

The purpose of this utility model is to provide a kind of utilization to have the colourless transparent plastic packaging film now, is made into the antifalse packaging film of purpose made anti-fake mark thereon.

The utility model antifalse packaging film is the colourless transparent plastic film, and as polypropylene screen, polychloroethylene film, polyester film etc., its thickness is generally 10～100 microns.Have on the film by laser-hologram purpose made metallograph, impress out as the nickel version with pattern and the different concavo-convex impression of the corresponding depth of literal, promptly on transparent plastic film, impress out three-dimension effect two dimension, three-dimensional geometric shapes extremely strong, that level is distinct, various patterns such as animal flowers and plants.Concavo-convex depth of indentation is generally 0.1～10 micron.This indentation pattern, literal can be distributed on the whole packaging film, also can be distributed on some ad-hoc location of packaging film.For increasing its anti-counterfeiting performance, also can adopt continuous laser photography, behind multiexposure, multiple exposure on the photoresist sheet, the specific nickel version of producing again, it is different to impress out the depth, and overlapping, that encrypt or the dynamic pattern of concavo-convex impression, literal etc.

The advantage of the utility model antifalse packaging film is because water white transparency, and the pattern above the packaging bag of commodity, carton, can, the glass bottle etc. is had no effect.But under certain lighting angle, can demonstrate can't pseudo-emit dynamic or static again significantly, the extremely strong laser of three-dimension effect is suffered from pattern, literal entirely.Both increased the attractive in appearance of external packing.Have very high security feature again, and can be used for commodity automatic packaging manufacturing line, be specially adapted to the packing of a cigarette, economical convenient.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 1～Fig. 2: the utility model structural representation.

Fig. 3: the A-A cutaway view among Fig. 1.

The utility model antifalse packaging film is a water white transparency polyester film 1, have on it impress out by laser-hologram purpose made metallograph with pattern and the different concavo-convex impression of the corresponding depth of literal, be butterfly pattern 2 and " butterfly " literal 3, under certain lighting angle, show " butterfly " literal 3 at the back layer, butterfly pattern 2 is at the laser hologram two-dimensional image of anterior layer.

Claims

1, a kind of antifalse packaging film comprises the colourless transparent plastic film, it is characterized in that having on the film impress out by laser-hologram purpose made metallograph with pattern and the different concavo-convex impression of the corresponding depth of literal.

2, antifalse packaging film according to claim 1, the degree of depth that it is characterized in that concavo-convex impression is 0.1～10 micron.
