Compared with traditional labels, self-adhesive labels have the advantages of no need for gluing, no need for pasting, no need for dipping in water, and saving labeling time. They have a wide range of applications and are convenient and fast. Self-adhesive is a material, also known as self-adhesive label material. It is made of paper, film or other special materials, with adhesive on the back. Yigajqi is a composite material made of coated silicon protective paper as the base paper, and after processing such as printing and die-cutting, it becomes a finished label. 1. Transparent self-adhesive has low cost and fast production speed. Because transparent stickers are mostly used for trademarks and self-adhesive labels, the printing area of the products is relatively small, and the printing speed is also relatively fast. A large number of transparent stickers can be printed in a short time, improving labor productivity and self-adhesive. In addition, the waste generated by the printing of transparent self-adhesive is less, saving manpower and time for waste disposal for enterprises. 2. Transparent self-adhesive has diverse printing methods and is more flexible. Transparent self-adhesive can be printed by various equipment. It can be printed using a single-sheet paper printing method similar to offset printing, or by using screen label printing, flexographic printing, etc. 3. Transparent self-adhesive printing is easy and the steps are simple. The printing of transparent self-adhesive only consists of three processes: the cutting process, the plate-making and color-mixing process, and the printing process. When using it, simply peel off the backing paper and press it gently onto various substrates, or use the labeling machine on the self-adhesive label production line to automatically label. Commonly used ones include pharmaceutical labels, food labels, wine labels, battery labels, outer box labels, shampoo labels, barcode labels, semi-finished product temporary labels, etc., classified into basic labels and variable information labels according to their uses. Scope of application. What are the cutting methods for self-adhesive labels? 1. Cutting process. This process makes the application of self-adhesive stickers more widespread, and is mostly used on irregular self-adhesive stickers. Self-adhesive cutting is for those irregular or irregular self-adhesive printed products, which need to be cut by a cutting knife. In this way, the shape of the printed product is no longer limited to straight edges or right angles, which is conducive to the shaping of the product. 2. Stamping/Stamping Silver process. This process is rarely used, the process is complex, and the cost is high. Self-adhesive printing is generally used for LOGOs, labels, trademarks, etc. Self-adhesive gold and silver stamping process is using the heat transfer printing principle to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate, forming a special metal effect, which is to increase the surface decoration of self-adhesive labels and can increase the added value of the product. In addition, self-adhesive gold and silver stamping gives products high anti-counterfeiting properties. Yes. Shanghai Haohao Label Products Co., Ltd. was established in 2010.

Firstly, we need to understand the basic structure and functions of each part of the self-adhesive material as a printing material. The structure of the adhesive consists of the facing material, the adhesive, and the backing paper. From the perspective of manufacturing process and quality assurance, the adhesive is composed of seven parts: 1. Back coating or back printing Back coating is to apply a protective coating on the back of the backing paper to prevent waste from escaping, and the adhesive around the rewinding label adheres to the backing paper. Another function is to create multi-layer labels. Back printing is to print the registered trademark and patterns of the manufacturer on the back of the backing paper, serving as an advertising and anti-counterfeiting function. 2. Surface coating It is used to modify the surface properties of the material. It increases surface tension, color change, adds a protective layer, etc., making it easier to absorb ink, easier to print, resistant to stains, increasing the adhesion of the ink, preventing the printing graphics from falling off. Surface coating is mainly used for non-hygroscopic materials such as aluminum foil, coated paper, various films, etc. 3. Facing material The facing material is a kind of material that can receive printed graphics on the front and adhesive on the back, and be applied to the final attached object. Generally speaking, any deformable material that can be bent, such as commonly used paper, film, composite foil, various fabrics, thin metal sheets, rubber, etc., can be used as the fabric of self-adhesive materials. The type of facing material depends on the final application and printing process. The facing material must be compatible with printing printing, have good ink absorption, and be strong enough to withstand various processes such as die-cutting, water extraction, slitting, die-cutting, labeling, etc. 4. Adhesive The adhesive is the medium, serving as the connection between the label material and the adhesive base material. According to their characteristics, they are divided into two types: long-term type and detachable type. Different formulas are suitable for different surfaces and different occasions. The adhesive is a key component of self-adhesive material technology and also a key component of label application technology. 5. Release coating (silicone coating) is to apply a layer of silicone oil on the surface of the backing paper. It can prevent the adhesive from sticking to the backing paper. 6. Backing paper The role of the backing paper is to receive the release agent coating, protect the adhesive on the back of the surface layer, support the surface layer, so that it can be die-cut, waste discharge, and be labeled on the labeling machine. 7. Primer The primer is the same as the surface coating, but it is applied on the back of the surface material. The main purpose of the primer is: (1) To prevent the surface material from being penetrated by the protective adhesive. (2) To increase the opacity of the fabric. (3) To increase the bonding strength between the adhesive and the surface layer material. (4) To prevent the plastic surface material from allowing plasticizers to penetrate into the adhesive. This will affect the adhesion performance and cause the label's cohesion strength to decrease and the label to fall off.

1. Anti-counterfeiting lines and anti-counterfeiting labels (1) Process: The thread shape is generally straight, or it can be wavy, zigzag, etc. The exposed metal wire is copied as intermittent black lines, which cannot be reproduced. (2) Features: The paper base is embedded with different colored metal wires or polyester plastic wires. The paper base is seen to be filled or intermittently (with windows) with wires. 2. Magic mirror anti-counterfeiting technology (1) Technology: The magic mirror anti-counterfeiting technology of Zhongshang uses magnetic-induced color-changing new nano materials, so the color and pattern of the label will change with the variation of the external magnetic field. This technology realizes the batch production of uniform nanoparticles, and the technology is advanced, and it is an innovative anti-counterfeiting technology. (2) Query methods: Verification method 1: Cover the magic mirror label with an eraser magnet or a mobile phone speaker, and observe the color change of the label. Verification method 2: If the substrate is too thick and cannot place a magnet on the back, a ring-shaped magnet detector can be used to observe from the front, making the manufacturing cost of the detector very low. Or use removable labels. 3. First ring anti-counterfeiting technology features: Double-sided invisible pattern effect, which can be recognized on the mobile phone screen, providing a good LCD anti-counterfeiting solution. Technology: The front sheet itself is semi-transparent, not affecting the visual effect of the graphics and text below. If the image and text below are dark, the previous film may have angle-related color effects. Turn on the mobile phone screen to make the hidden information clearly visible, rotate the mobile phone screen to alternate the hidden information between light and dark. 4. Holographic QR code anti-counterfeiting label Self-adhesive stickers, also known as paper, film or special materials made self-adhesive stickers, that is, stick, stick immediately, pressure-sensitive paper, etc., is a composite material made of coated silicon protective paper as the base paper, which can be processed by punching and other processing methods, and then become finished stickers. Just remove it from the base paper and touch it to apply to various substrates, or use a labeling machine to automatically apply to the production line. Compared with traditional self-adhesive stickers, self-adhesive stickers are non-stick, non-attachment, non-water immersion, pollution-free, and save your labeling time. Paper stickers depend on the fabric, adhesive and base paper. The adhesive is a very useful sticker. Self-adhesive printing is very different from traditional printing. Self-adhesive printing is usually processed and printed on a self-adhesive linkage machine, completing multiple processes such as graphic printing, die-cutting, layout, etc. in one time. So one end is the input of raw material total quantity, and the other end is the output of finished products. The finished products are divided into张贴 or roll-up， and the finished stickers can be directly stuck on the product. Therefore， the printing process of self-adhesive stickers is more complex， and the requirements for equipment performance and printing personnel quality are also higher.

Before using different types of self-adhesive labels, it is important to test the type of the self-adhesive to see if it is a glue, heat-seal adhesive or self-adhesive paper. Some adhesives react with certain substances. For example, the stickers used as signs may contaminate certain special fabrics under certain conditions. Some labels require temporary stickiness, and will have continuous stickiness under exposure conditions. On the other hand, some labels require continuous stickiness, losing some surface stickiness. Problems often occur when using stickers and other labels on the surface of recycled paper. During the recycling process, there are many different types of paper, and some of them may be contaminated by silicon or wax coatings, thus contaminating the final recycled product. When using labels on these contaminated recycled paper surfaces, the adhesives often lose their effectiveness. Note: The role of the organic silicone coating in adhesive labels is to ensure that the adhesive can easily separate from the liner paper. Low temperatures can also cause problems. Low temperatures reduce the speed of adhesion, and the labels may have peeled off the surface before adhering to it. If the labels are not stored properly - with large temperature differences, significant humidity fluctuations, or improper stacking - the labels will lose stickiness shortly after use. One of the important factors for effective use of stickers is to correctly peel the stickers from the backing surface. Many people separate and pull out the stickers from the left and right corners, which reduces the stickiness of the contact area of the adhesive and also damages the "surface fibers" in the material, causing the labels to curl. The correct way to remove the labels from the backing surface is to keep the labels straight and peel the labels from the top or bottom center to ensure a good combination of the label with the surface of the object.

There are various printing methods for label production, mainly including embossing printing, offset printing, screen printing, flexographic printing, etc. Different label printing methods have their own characteristics. So, which method is the best to choose? Let's analyze it together. In China, label printing is mainly done using embossing printing, offset printing and screen printing. However, in other more developed regions in Europe and America, flexographic printing is more commonly used. With the continuous improvement of the plate-making level in China in recent years, the comprehensive cost of flexographic printing is constantly decreasing. Due to its low investment and high output characteristics, it has attracted more and more label printing manufacturers. From a long-term application perspective, flexographic printing will be the choice for label printing. Of course, in addition to this, in order to print exquisite labels, other processes need to be combined, which is what we call combined printing. It integrates the advantages of various printing methods to form a more excellent and exquisite combination. Currently, in the label field, it is increasingly favored. Combined printing not only can complete the printing and processing at one time, improving production efficiency, but also can significantly reduce the cost of label printing. It is an ideal choice for label printing. Shanghai Haohao Label Products Co., Ltd. was established in 2010.

Self-adhesive printed products are a common form of product description and promotion nowadays. For instance, various cosmetic bottle surfaces may be covered with a plastic film printed with product information, which is also produced through transparent self-adhesive printing. Currently, the application of transparent self-adhesive has become very widespread, being incorporated into trademarks, product descriptions, and other aspects. Its effect on products is unparalleled. Transparent self-adhesive is a process where preformed patterns, labels, and textual descriptions of different natures are transferred from the printing plate to the excellent transparent plastic film pre-coated with a glue layer, thereby forming self-adhesive transparent printed products with adhesive properties. Transparent self-adhesive label printing has led to greater progress in printing, with a significantly lower error rate compared to screen printing, and it can also be produced simultaneously with the product, saving a lot of time. Transparent self-adhesive labels are widely used, covering fields such as food, medicine, cosmetics, electrical appliances, stationery, daily necessities, electronic products, and more. Additionally, there are many applications for clothing labels, supermarket product price tags, etc. To a certain extent, transparent self-adhesive has become an indispensable part of product production, bringing great benefits to product promotion and enterprises.

The barcode itself does not have the function of information storage. It needs to be scanned and connected to a barcode system server, and then the result can be fed back to the scanning device. This requires not only considering the printing production of the barcode during its creation, but also the barcode query system behind it. Only by integrating the internal system and the external display can the various functions brought by the barcode, such as inventory management, anti-counterfeiting, product information, etc., be achieved. First, let's talk about the display of external information of the barcode. This requires an independent printing factory and professional printing equipment to facilitate the addition of anti-counterfeiting printing techniques and technologies to enhance the anti-counterfeiting performance of the final barcode label. Enterprises should be aware that some manufacturers may not have the anti-counterfeiting printing capabilities. They do not have their own printing factories, and the printing equipment may be obsolete. They complete the product production by outsourcing to other factories. In this way, there is no guarantee in terms of the materials, ink, glue, etc. used, and problems are difficult to solve. Next, let's take a look at the internal system of the barcode. This requires professional anti-counterfeiting technicians to build it according to the enterprise's needs. Some enterprises may want to realize the scanning of barcodes for inventory management, or some want to realize the display of product information, authenticity status, and counterfeiting information. These can all be customized according to the enterprise's needs. However, many manufacturers do not have this capability. They outsource this to technology companies. This has led to the problem of difficult maintenance later on. It is necessary to find those genuine anti-counterfeiting companies with a technical research and development team and successful cases.

With the rapid economic development, the consumption demands of the consumer group have become increasingly diverse. Both the visual artistic effect and the high-quality living needs are gradually improving. In the fierce printing competition market, in order to enhance the elegance of packaging printing products, to effectively improve the anti-counterfeiting degree of packaging, to better increase the added value of products, and to improve the advertising effect of products, more and more packaging printing products have adopted stamping technology. Because the stamped products are exquisite, upscale, have individuality, strong metallic texture, and strong anti-counterfeiting performance. Stamping in the industry is also called "gold stamping and silver stamping" technology. The substrates for stamping generally include paper, cardboard, plastic, wood, glass, leather, textiles, etc. Those who apply stamping technology usually include the covers and bottoms of hardcover books, cigarette boxes, wine boxes, cosmetic boxes, product labels, wallpaper, wooden boxes and containers, glass products, textiles and clothing. The stamping process is an important decorative process in daily product packaging. Stamping technology is classified by stamping methods, and it is divided into hot stamping and cold stamping. Both hot stamping and cold stamping have their own technical advantages. The greatest advantage of cold stamping is low cost and high cost performance, which is also the biggest selling point of cold stamping technology. For customers, the cost performance of cold stamping technology is relatively high, which can help customers increase the added value of products, and is very economical and reasonable. In addition, cold stamping is very suitable for short-run jobs, low-quality requirements labels and proofing production. Cold stamping technology provides new opportunities for most printing enterprises. However, compared with hot stamping technology, cold stamping technology still has certain defects in quality, which need to be further improved. Therefore, cold stamping technology is not very suitable for processing high-quality packaging and label products. In actual production, using hot stamping technology can achieve good stamping quality and effect, but the cost is higher. Shanghai Haohao Label Products Co., Ltd. was established in 2010. It is a professional roll printing label manufacturer, which can provide customers with overall solution of identification based on label design.

Self-adhesive materials are also known as self-adhesive label materials. They are composite materials made of paper, film or special materials, with adhesive on the back and a silicone-coated protective paper as the base paper. Due to the variety of coating techniques, self-adhesive materials can form different grades. Currently, the development direction is from traditional roller coating, scraper coating to high-pressure extrusion coating to maximize the uniformity of coating, avoid the generation of bubbles and pinholes, and ensure the coating quality. However, high-pressure extrusion coating technology is not yet mature in China, and domestic production mainly adopts traditional roller coating.  Self-adhesive materials are also known as self-adhesive label materials.

However, high-pressure extrusion coating technology is not yet mature in China, and domestic production mainly adopts traditional roller coating. Self-adhesive printing categories: hot stamping printing, letterpress printing, silk screen printing, roller printing self-adhesive label categories: light writing paper, offset paper labels, coated paper, mirror coated paper label, the non-drying label, aluminum foil adhesive labels, laser wrong shoot film adhesive label, the non-drying label, easy shredding thermal paper adhesive labels, adhesive labels, thermal transfer paper, can be removed Glue the non-drying label, washable plastic adhesive label, etc.

Currently, there are more than ten types of anti-counterfeiting labels commonly used for packaging, such as anti-pull seals (labels), anti-counterfeiting logo labels, anti-pull labels, fragile paper labels, laser holographic labels, laser holographic destructive labels, letter mold anti-counterfeiting polyester film labels, transparent PVC letter mold anti-pull universal labels, comprehensive anti-counterfeiting anti-pull embossed paper labels, product code holographic labels, product code scratch-off labels, foam film labels, barcode technology labels, and other personalized labels, etc. 1. Anti-pull sealing anti-pull sealing is a peelable type of non-adhesive anti-counterfeiting seal made of plastic film. Before peeling, it is a colored non-adhesive plastic strip without text; after peeling, a distinct colored text can be seen on the paper, such as "The seal has expired OPENED", and on the plastic strip, a distinct non-colored text can be seen, which has the characteristics of one pull damage, one damage reveal, one reveal knowing the authenticity, and non-reusable. It is mainly used in anti-counterfeiting envelopes, electrical warranty labels, etc. 2. Fragile paper label It is made of specially treated fragile paper or fragile non-adhesive materials, and can print trademarks, text descriptions and barcodes. After being pasted on the packaging, it cannot be fully peeled again. Once peeled, the paper will break. 3. Comprehensive anti-counterfeiting anti-pull embossed paper label This is a non-adhesive paper label made by integrating multiple anti-counterfeiting technologies. To prevent the label from being peeled, moved or reused, the cutting and embossing technology can be used to prevent the label from being peeled. After being peeled, it cannot be restored. 4. Barcode technology label A barcode is a code for goods, designed for effective management of goods using computers. Currently, there are many types of anti-counterfeiting barcodes, and the main ones are one-dimensional barcodes and two-dimensional barcodes. Applying barcode technology ingeniously to anti-counterfeiting packaging and product labels can not only promote their better and faster application, but also achieve the purpose of protecting famous and high-quality products from being counterfeited and protecting consumers' interests. 5. Laser holographic image label The application of laser holographic image technology in anti-counterfeiting packaging mainly involves printing anti-counterfeiting labels and trademarks. The factors affecting the anti-counterfeiting performance of laser holographic labels are mainly the type of the label and its usage position. The types of laser holographic anti-counterfeiting labels include the following. 1. Non-adhesive type: The holographic anti-counterfeiting graphics are made on non-adhesive materials, and no adhesive needs to be applied when using it, and it has better adaptability to machinery. Its major disadvantage is that it can be reused, allowing some lawbreakers to make counterfeit products using old packaging and labels, thus affecting the anti-counterfeiting effect of the anti-counterfeiting label. 2. Anti-pull type: The anti-pull type label makes up for the shortcomings of ordinary non-adhesive labels. When the label is peeled from the packaging, the holographic image on the label is completely destroyed and cannot be reused. It can prevent the behavior of using old labels to make counterfeit products. 3. Stamping type: Stamping type is a non-peelable holographic anti-counterfeiting label. It is stamped onto the packaging material using a stamping machine and integrates with the packaging material. If the stamping position is reasonably selected, its anti-counterfeiting effect will be better than the above two types. 6. Letter mold anti-counterfeiting polyester film label: Before peeling, it is an aluminum foil non-adhesive strip without text. After peeling, distinct colored text can be seen on the label and the packaging material. 7. Transparent PVC letter mold anti-pull universal label: Before peeling, it is a white non-adhesive film label without text. After peeling, distinct colored text can be seen on the label and the packaging material. 8. Transparent PVC anti-counterfeiting label: On non-adhesive labels or other documents, a personalized information transparent laser holographic film is attached, which does not affect the overall design and original effect and increases the anti-counterfeiting function, making the label personalized. 9. Foam film label Foam film labels are a unique semi-glossy white film made of two layers of polystyrene films. The surface layer is a transparent film, suitable for printing; The lower layer is a white foamed film that has been expanded. It is bonded with a long-term acrylic adhesive and exhibits excellent high viscosity performance on various substrates. The foam film labels have a very good security anti-counterfeiting effect. When the label is stuck to the substrate and then removed, the two layers of film will separate, indicating that the product packaging has been opened; and the residue of the foam layer will remain on the packaging, making it difficult to remove. The foam film labels have the moisture resistance of a film and are suitable for use in humid environments. Especially in the production and packaging processes of beverages, dairy products, etc., they have extraordinary practical value. They are applicable to safety labels for glass PVC, polystyrene bottles, and glossy cardboard boxes, etc. 10. Partially peeled paper-based labels The label substrate is coated paper (special paper can also be used), and can be printed by intaglio, relief, or offset printing. Different from ordinary peelable digital anti-counterfeiting labels, when the upper part is peeled off, the lower layer will leave data for consumers to input and query. This label cannot be reused. When used as a seal, it is firmly attached and not likely to fall off. If combined with special paper printing and the digital anti-counterfeiting network system, it has multiple anti-counterfeiting functions. 11. Regularly peeled composite anti-counterfeiting label This anti-counterfeiting label belongs to self-adhesive anti-counterfeiting labels. When using, the label is directly attached to the product. When identifying, the label is quickly peeled off, and the packaging will leave pre-designed invisible graphics in the form of positive images; on the peeled label, there will be invisible graphics in the form of negative images, which are opposite in nature, the same in size, and equal in quantity. No need to use any instruments or equipment for identification. It has the characteristics of being damaged when peeled, revealing the authenticity when damaged, and knowing the authenticity when revealed, and cannot be reused. The label can use materials such as holographic film, coated paper, and plastic film as the surface material, and is suitable for flat attachment and sealing of various materials. As a high-tech anti-counterfeiting product, its price is comparable to that of similar anti-counterfeiting labels with coated paper. 12. Product code (digital) label The telephone code anti-counterfeiting project (also known as the digital anti-counterfeiting network system) has developed rapidly in China in recent years and has been widely used for the anti-counterfeiting of various domestic products. As an important carrier label of this system project, there are mainly three types: paper-based scratch-off type, peel-off type, and holographic scratch-off type. 13. Holographic peel-off type peel-off label After peeling off the holographic reveal type peel-off label, part of the label is regularly revealed, showing the predetermined graphic information; its surface is hollowed out, and the graphics left on the bottom layer are opposite in nature; the bottom part of the label leaves a number for consumers to input and query. This label cannot be reused. It has all the characteristics of "holographic regular reveal anti-counterfeiting label". As a sealing use, it has stable adhesion stability and can be combined with the digital network anti-counterfeiting system to have multiple anti-counterfeiting functions.
