deficiencies of cosmetic packaging and improvement measures

Cosmetic packaging anti-counterfeiting printing technology

Anti-counterfeit packaging technology is to use packaging to prevent goods in the process of circulation and transfer to be consciously stolen and counterfeit technology and methods. Daily cosmetics are similar to cigarettes and alcohol, both of which are commodities with large sales volume and high profits. It is reported that daily cosmetics are the most counterfeit products only second to tobacco and alcohol. Therefore, how to carry on the anti-counterfeit packaging of these commodities, it is very important.

1. Present situation of anti-counterfeiting technology in packaging of daily cosmetics

At present, there are many kinds of cosmetics for daily use in the market, and the packaging is countless. Among them, the mainstream of packaging is: Most cleansing products are plastic packing, wash hair product USES plastic column packing, beauty skin care products using glass bottles, plastic pipes or plastic box packaging, plastic bags, and some commonly used toothpaste products are composite tube packing, heavy use of aluminum tube packing has to be eliminated before, In the outside of these packages are generally also used for a carton packaging, soap products using carton or plastic box packaging.

No matter how its cosmetics packaging form, the anti-counterfeiting packaging of daily cosmetics is generally designed according to the following four aspects: printing material anti-counterfeiting, printing process anti-counterfeiting, printing ink anti-counterfeiting, packaging design anti-counterfeiting.

1) Anti-counterfeiting technology of cosmetic packaging printing materials

In recent years, material technology has made great progress in packaging anti-counterfeiting after combining with other technologies. At present, the main anti-counterfeiting materials used in daily cosmetics packaging are: anti-counterfeiting holographic paper, gold and silver card, gold and silver laser card paper.

① cosmetic packaging anti-counterfeiting holographic transfer paper

Anti-counterfeiting holographic transfer paper, also known as vacuum aluminized film transfer paper, uses the holographic information to be pre-molded on a specific film by molding process, and carries out vacuum aluminization, and finally transfers the aluminized layer to the surface of the paper. Holographic transfer paper plays an important role in the field of anti-counterfeiting packaging because of its ideal printability and the remarkable anti-counterfeiting function of holograms on the paper. In addition, holographic transfer paper does not contain plastic film, as a fashion environmental protection anti-counterfeiting packaging material is currently widely used in food, medicine, cosmetics, tobacco and other outer packaging.

② cosmetics packaging gold and silver card, laser card paper

Gold and silver card, laser card are aluminum plated card. Gold and silver card paper is also known as gold and silver foil paper, is composed of aluminum foil layer with coating (or spray aluminum layer or aluminum plated PET film) and card. The surface of the paper is smooth and bright, with metallic luster, mainly used for high-grade packaging of cigarette boxes, wine boxes, cosmetics boxes. Laser card is also known as the laser rainbow card, not only the image is clear and bright, colorful, even if printed on the dark ink can not cover the rainbow effect, permeability is very good. Because of gold and silver card, laser card paper price is higher, and the paper surface image is different from the general paper, plus the special effect after printing, so that the packaging has a certain anti-counterfeiting effect.

2) Cosmetic packaging printing ink anti-counterfeiting technology

Fluorescent ink.

Fluorescent ink is made of fluorescent material dissolved in the corresponding resin, its main component is fluorescent pigment, when the external light irradiation, absorption of a certain form of energy, does not convert into heat energy, direct excitation of photons, in the form of low visible light will be released energy, resulting in different hue fluorescence phenomenon. Prints printed with fluorescent ink have bright colors and good decoration effect. Under the action of visible light and ultraviolet light, they emit sparkling fluorescence. Anti-counterfeiting packaging with fluorescent ink to their own deployment of the best anti-counterfeiting effect, different formulas can get different fluorescent effect, generally difficult to carry out realistic prevention.

② Cosmetic packaging heat-sensitive anti-counterfeiting ink.

Under heating conditions, the discoloration effect of the ink is called thermosensitive anti-counterfeiting ink, according to the discoloration required temperature is different, can be divided into hand temperature discoloration ink and high temperature discoloration ink. The basic component of thermal anti-counterfeiting ink is color color pigment, because the color changes before and after heating these pigments are completely different, as a basis for judging whether the trademark or product is forged, not only easy to identify, but also fast.

(3) cosmetic packaging light activated color changing ink.

Photochromic ink is due to the ultraviolet radiation and discoloration, in the sun or ultraviolet light irradiation can be from colorless to blue, purple, yellow and other colors, can also change from one color to another color. Its discoloration principle is: when the sun or ultraviolet light irradiation to the ink, the ink in the photosensitive material is excited, its molecular structure changes, resulting in the appearance of color changes. When the external stimulus is removed, the photosensitive material molecules in the ink return to the original ground state, and the ink returns to its original color. This kind of ink is widely used in anti-counterfeiting packaging printing of daily cosmetics.

3) Anti-counterfeiting technology of printing process

(1) Cosmetics packaging frosted printing.

Frosted printing, also known as metal-imitating etching printing, is a unique process of screen printing on a substrate with a metallic mirror-like luster, such as gold and silver cardboard. Frosted glass printing ink formulation contains some of the granular material, at the time of these particles with ink printing on substrates, after UV radiation curing, formed the uneven shape of sand particles, the rough face of diffuse and not part of printing ink printability of specular reflection of light formed bright contrast, Thus a relief like three-dimensional effect can be obtained. Part of the packaging of Jingtianlixue cosmetics, produced by Shenzhen sapphire co., LTD., adopts the grinding process on the gold card paper, which makes the packaging noble and solemn, and the effect is very good.

② Cosmetics packaging microprinting.

Microform printing refers to the printing of extremely small words on what looks like a dashed line, solid line or part of a pattern of ordinary printing to the naked eye. When observed with a magnifying glass or microscope, the words, codes or images in microform can be seen. Microform printing because of the very fine strokes, only strict control of film production, plate printing, printing technology and other processes, in order to make microform characters not empty. Microform printing is mainly used for commercial paper printing and has been widely used in medicine and cosmetics packaging in recent years. At present on the market is hot - selling Jiuxin group mite products on the use of this anti-counterfeiting technology.

4) Cosmetic packaging design and identification anti-counterfeiting technology

Laser hologram identification for anti-counterfeiting

Laser hologram is made by using the principle of laser interference and the method of spatial frequency coding. Laser hologram not only has a vivid image, but also presents multiple levels in space and decomposes a variety of colorful colors. The colors can also be changed according to the change of observation Angle, with a very high information content. The dynamic holography technology, dot matrix holography technology, invisible encryption technology and so on, which make holographic anti-counterfeiting technology have the characteristics of first-line anti-counterfeiting and second-line anti-counterfeiting, and become one of the most widely used anti-counterfeiting technology with the strongest anti-counterfeiting ability. At present, most of the material for daily cosmetics packaging on the market are jie type laser holographic anti-counterfeiting mark, general this logo stick on the front of daily cosmetics packaging or open place, when consumers buy after peeling the hologram that is destroyed, the logo's reuse is impossible, so it has good anti-counterfeiting effect. The Yifuxiang series cosmetics produced by Guangzhou Yifuxiang Chemical Research Institute have adopted this anti-counterfeiting technology.

(2) Cosmetics packaging coding anti-counterfeiting

Coding technology is to spray liquid ink through a very small nozzle to the substrate, and in a non-contact way to achieve graphic production, most of the printing is controlled by computer. Food, beverage, medicine, tobacco, daily cosmetics and other industries are suitable for the use of inkjet printing technology, the production date, batch number and other information on the outer package of the product, by adjusting the location of the printing anti-counterfeiting. If the use of anti-counterfeiting ink inkjet can receive better anti-counterfeiting effect. The size and shape of the printed font can be realized by computer coding, and a data set can be randomly formed, which corresponds to the size and shape of the printed font to form the secret orientation.

③ cosmetics packaging telephone code identification anti-counterfeiting

Telephone code anti-counterfeiting technology is a kind of anti-counterfeiting packaging technology which networked the packaging information, and it is also a kind of anti-counterfeiting technology which is most conducive to consumer identification. Its basic principle is on the label to each piece of product with password, a yard, should have no weight code, the same product with a query number and label them, consumer wherever and whenever, called query as long as to enter product coding according to the prompt, you can know the authenticity of a product, needed to pay phone bill for the manufacturer. Because counterfeiters cannot send the forged product code files to the anti-counterfeiting center to be stored in the database, this technology is not forgeable. There are two main ways of application of this anti-counterfeiting technology in cosmetic packaging: paper-based scraping and laser hologram scraping.

(4) cosmetic packaging bar code identification security

Bar code is by a group of different width, different reflectivity bars and empty, according to a certain code combination, used to represent a group of data symbols. Goods on the market at present cannot be circulated without a bar code. Commodity bar code itself does not have the ability to prevent counterfeiting, it is just a kind of code of goods, in order to use the computer to the effective management of goods designed. If you choose a specific printing position, choose a special ink, choose a special printing method, use a special encryption method, can make the bar code has the function of multiple orientation. It is difficult for the general consumer to identify the bar code, only to find the technical supervision department to judge, so it is a second-line anti-counterfeiting technology.
