Problems solved by technology

The deficiency of this anti-counterfeiting method is: the carrier that is loaded with effective anti-counterfeiting identification feature may be used for counterfeit goods
The advantage of this kind of anti-counterfeiting packaging is that it is difficult to imitate, the probability of the same random anti-counterfeiting identification features of different anti-counterfeiting objects is very low, and the identification information of anti-counterfeiting features is very accurate. When the packaging is a one-time use packaging, it can also avoid carrying The packages with effective anti-counterfeiting marks are recycled for packaging fake products, and the disadvantage is that the random distribution of colored sundries is less easily identifiable and easy to describe

Embodiment 1

[0090] as attached Figure 1-6 As shown, the anti-counterfeiting object of this embodiment is the carton 2 with the printer ink cartridge inside, and a single-layer BOPP transparent heat-shrinkable film roll is used. One side of the heat-shrinkable film roll is molded with regularly distributed numbers with laser holograms. Laser holographic grid pattern 4, the side length of the grid is 5cm. The heat-shrinkable film roll is placed on the heat-cut packaging machine, and the carton 2 is heat-cut and packaged in the heat-shrinkable film 1 from the heat-shrinkable film roll by the heat-cut sealer, and the heat-shrinkable film 1 encapsulating the carton 2 is placed on the The conveyor belt of the heat shrinking machine enters the heat shrinking machine for heating, so that the heat shrinkable film 1 is tightly wrapped on the carton 2, and the temperature in the heat shrinking machine is kept between one-third and two-thirds of the heating time during heating. Randomly change with...

Embodiment 2

[0093] as attached Figure 7-12 As shown, the anti-counterfeiting object of the present embodiment is the carton 2 containing the medicine. One side of the carton 2 is covered with gold reference grids 7, and the green number 8 is printed in the reference grid 7. In addition, the carton 2 The authenticity inquiry phone number and website are printed on the surface of the carton. The circumference of the carton 2 is 200mm and the length is 100mm; the heat-shrinkable film package 1 is a heat-shrinkable film packaging bag made of transparent polyethylene heat-shrinkable film tube film. 1. On the material body of the heat-shrinkable film tube, there are some English letters composed of many nuclear track micropores and nuclear track pits 9, both in upper and lower case, arranged regularly but in random order 4, the heat-shrinkable film The circumference of the tube is 250mm, and the length of the heat-shrinkable film packaging bag 1 is 150mm; first, the carton 2 is eagerly sealed ...

Embodiment 3

[0096] as attached Figure 13-16 Shown, the anti-counterfeiting object of the present embodiment is laundry soap 2, and the length of this laundry soap 2 is 150mm, and width is 75mm, and thickness is 40mm, adopts the transparent single-layer polyethylene heat-shrinkable film roll material that width is 300mm, in this heat One side of the shrink film roll is gravure printed with many randomly distributed green solid regular triangle patterns 4 with red numbers printed in the middle, and the side length of the triangle is 5cm. Cut the heat-shrinkable film roll into 300mm×450mm single-sheet heat-shrinkable film 1 first, and use an inkjet printer to print on one side of each piece of laundry soap 2 a 16-digit The sequence code composed of Arabic numerals is used as the query code, and each piece of laundry soap 2 is packaged by a hot cutting machine with a single shrink film 1, and the side 6 with the pattern 4 is gravure printed as the inner surface, and the laundry soap packaged...

Abstract

The present invention belongs to the field of anti-fake packing technology, and is especially one anti-fake method utilizing thermal contraction film and random characteristic. The packing material of thermal contraction film with some pattern is used to pack matter in anti-fake mode and is heated according to the technological requirement, so that the thermal contraction film covers the packed matter closely. The random characteristic of the pattern in the contracted film and / or the relative position characteristic of the packed matter to the pattern are used as the anti-fake identification characteristic. The main advantages includes the hard-to-forge anti-fake characteristic and the anti-fake packing incapable of being reused.

Description

(1) Technical field [0001] The invention belongs to the technical field of packaging anti-counterfeiting, and in particular relates to an anti-counterfeiting method using heat shrinkable films and random features. (2) Background technology [0002] Packaging anti-counterfeiting can be used for anti-counterfeiting of some commodities that are inconvenient to paste anti-counterfeiting labels, and because it does not need to be pasted, it is easier to use than anti-counterfeiting labels, and it can also avoid the problem that the real anti-counterfeiting labels are completely peeled off and pasted on fake products, but general anti-counterfeiting packaging Things are easy to be recycled and packaged by counterfeiters. [0003] Heat shrinkable film is a widely used one-time use packaging material, which can avoid being reused. If a method of anti-counterfeiting using heat shrinkable film can be invented, it will not only prevent the genuine anti-counterfeit label from being peel...
