Description
Technical Field
The invention belongs to the technical field of anti-counterfeiting packaging, and particularly relates to an anti-counterfeiting heat shrinkable film and a preparation method thereof.
Background
The heat shrinkable film is widely applied to the outer packaging of various products such as food, tobacco, tea, medicines, cosmetics, health care products, sterilized tableware, gifts, hardware plastic products, electronic appliances and the like, and particularly can meet the functions of moisture prevention, dust prevention, touch stealing prevention, transparent display and the like of commodities and increase the appearance attraction of the products in the aspect of combined (bundling) packaging of irregular-shaped objects or commodities.
After a product is packaged, in order to obtain some information of the product, such as the brand, the production place, the use instruction, the components, the anti-counterfeiting mark and the like, from the package when people buy the product, some characters, figures, the anti-counterfeiting mark and other marks need to be formed on a packaging film. In the existing packaging film composed of the heat shrinkable film, the marks such as the characters, the figures, the anti-counterfeiting marks and the like are printed or directly formed on the packaging film by other modes, and after the packaging film is coated outside a product, the information marked by the marks is displayed outside the packaging film for a purchaser or a user to identify. However, since these packaging films made of heat shrinkable films are plastic films which finish products by heat shrinkage characteristics, marks printed on the packaging films are deformed after being wrapped on products by heat shrinkage deformation, thereby causing the marks on the packaging films to be unclear, greatly affecting the mark recognition effect, and also affecting the beauty of the packaging films. Particularly, the anti-counterfeiting mark directly formed or printed on the heat shrinkable film is used for distinguishing the authenticity of a product, but the anti-counterfeiting mark becomes blurred after heat shrinkage deformation, and is difficult to distinguish, so that the anti-counterfeiting function cannot be realized at all. Therefore, there is a need for a new heat-shrinkable packaging film that overcomes the above-mentioned deficiencies of the prior art packaging films.
Disclosure of Invention
The invention aims to provide an anti-counterfeiting heat-shrinkable film, which can ensure that a mark on the heat-shrinkable packaging film is basically not deformed along with the product after the product is wrapped by the heat-shrinkable packaging film in a heat-shrinkable way, thereby ensuring the identification effect of the mark; the invention also provides a preparation method of the anti-counterfeiting heat shrinkable film, which is scientific, reasonable, simple and feasible.
The anti-counterfeiting heat shrinkable film comprises a heat shrinkable film substrate layer, a safety line layer, an adhesive layer, a holographic information layer, a UV gloss oil layer and the heat shrinkable film substrate layer which are sequentially connected from top to bottom.
The width of the safety line layer is 2-5 mm.
The safety line layer is composed of a plurality of units, the length of each unit is 10-15mm, and the image contents of two adjacent units face upwards and downwards one by one.
The content on the safety line layer comprises a variable two-dimensional code and a chromatographic line; the variable two-dimensional code is a DM code, and color spectrum lines are formed by densely arranging 3-5 different color blocks according to a certain sequence.
The holographic information on the holographic information layer is one of a rainbow pixel surface, a dynamic light column or a pixel light spot, and the purpose of the holographic information layer is to enhance the appearance aesthetic feeling of a package and prevent the holographic information from being not clear any more due to shrinkage deformation of a shrink film.
The holographic information is transferred to the heat shrinkable film substrate by UV, rather than by embossing, to avoid distortion of the heat shrinkable film during embossing.
The thermal shrinkage rate of the thermal shrinkage film substrate layer is the same as that of the safety line layer, so that the quality problems of falling off or wrinkling and the like of the safety line layer and the thermal shrinkage film substrate layer caused by different thermal shrinkage rates can be avoided.
The preparation method of the anti-counterfeiting heat shrinkable film comprises the following steps:
(1) selecting a heat shrinkable film, printing UV gloss oil on the heat shrinkable film by using a flexographic printing machine, then compounding the heat shrinkable film with an OPP film with holographic information, drying the heat shrinkable film by using a UV lamp, peeling off the OPP film, copying the holographic information on the OPP film onto the heat shrinkable film, and respectively rolling up the OPP film and the heat shrinkable film;
(2) selecting a heat shrinkage film, printing variable two-dimensional codes, chromatographic lines and image-text contents related to products by using a digital printer, and then dividing the variable two-dimensional codes, the chromatographic lines and the image-text contents into safety lines;
(3) brushing an adhesive on the safety wire by using a glue brushing machine, and then compounding the safety wire on the heat shrinkable film obtained in the step (1).
The heat shrinkable film in the step (1) is an OPP heat shrinkable film or a PET heat shrinkable film.
The thickness of the heat shrinkable film in the step (1) is 10-50 μm.
The heat shrinkable film in the step (2) is an OPP heat shrinkable film or a PET heat shrinkable film.
The thickness of the heat shrinkable film in the step (2) is 12-20 μm.
The preparation method of the anti-counterfeiting heat shrinkable film comprises the following specific steps:
(1) selecting a heat shrinkable film with the thickness of 10-50 mu m, printing UV gloss oil on the heat shrinkable film by using a flexographic printing machine (two discharging devices and two receiving devices), then compounding the heat shrinkable film with an OPP film with holographic information, drying the heat shrinkable film by using a UV lamp, peeling off the OPP film so as to copy the holographic information on the OPP film onto the heat shrinkable film, and respectively rolling up the OPP film and the heat shrinkable film by using two receiving devices. The specific process parameters are as follows: the number of the printing rollers is 300-.
(2) Selecting a heat shrinkable film with the thickness of 12-20 mu m, printing variable two-dimensional codes, chromatographic lines and product-related image-text contents by using a digital printer, and then dividing the product into safety lines with the width of 2-5 mm.
(3) And brushing an adhesive on the safety wire by using a glue brushing machine, and then compounding the safety wire to the specified position of the heat shrinkable film.
Compared with the prior art, the invention has the following beneficial effects:
1. the heat shrinkable film can ensure that the mark on the heat shrinkable packaging film is not deformed along with the heat shrinkable packaging film after the heat shrinkable packaging film is wrapped outside a product, thereby ensuring the identification effect of the mark.
2. The invention endows holographic laser information on the thermal shrinkage film on the basis of not influencing the deformation of the thermal shrinkage film.
