Adhesive label structure
1. Noodles. It is the carrier of adhesive label content, and the back of the face paper is coated with adhesive. There are many materials that can be used for surface materials, generally including copperplate paper, transparent polyvinyl chloride (PVC), electrostatic polyvinyl chloride (PVC), polyester (PET), laser paper, heat-resistant paper, polypropylene (PP), polycarbonate (PC), kraft paper, fluorescent paper, gold-plated paper, silver plated paper, synthetic paper, aluminum foil paper, fragile (anti-counterfeit) paper, decorative paper, fabric label (Tyvek/nylon) paper, pearlescent paper, sandwich copperplate paper, and thermal paper.
2. Film layer material. Transparent polyester (PET), semi transparent polyester (PET), transparent oriented polypropylene (OPP), semi transparent oriented polypropylene (OPP), transparent polyvinyl chloride (PVC), glossy white polyvinyl chloride (PVC), matte white polyvinyl chloride (PVC), synthetic paper, glossy gold (silver) polyester, matte gold (silver) polyester.
3. Adhesive. Universal super adhesive type, universal strong adhesive type, refrigerated food strong adhesive type, universal re release type, fiber re release type. On the one hand, it ensures moderate adhesion between the base paper and the surface paper, and on the other hand, it ensures that the surface paper can have strong adhesion with the adhesive after being peeled off.
4. Base paper material. Release paper, commonly known as "base paper", has a low surface energy and non stick surface. The base paper has a separating effect on the adhesive, so it is used as an attachment for the surface paper to ensure that the surface paper can be easily peeled off from the base paper. Commonly used are white, blue, and yellow glassine paper or onion paper, kraft paper, polyester (PET), copperplate paper, and polyethylene (PE).
What are the types of adhesive labels?
Adhesive labels can be roughly divided into two types:
There are two types of stickers: paper stickers and film stickers
1. Paper stickers are mainly used for liquid detergent products and popular personal care products; Thin film materials are mainly used in mid to high end daily chemical products. At present, popular personal care products and household liquid cleaning products account for a large proportion in the market, so corresponding paper materials are used more
2. Thin film adhesive labels are commonly made of PE, PP, PVC, and other synthetic materials. The main types of thin film materials are white, matte, and transparent. Due to the poor printability of thin film materials, corona treatment or surface coating is generally used to enhance their printability. In order to avoid deformation or tearing of some film materials during printing and labeling processes, some materials are also subjected to directional processing, such as unidirectional or bidirectional stretching. For example, BOPP materials that have undergone bidirectional stretching are widely used for laminating writing paper, adhesive paper labels, and multi-purpose labels for information labeling and barcode printing labels. They are particularly suitable for high-speed laser printing and inkjet printing
Copperplate paper adhesive sticker is a universal label for multi-color product labeling, suitable for information labeling of drugs, food, edible oil, alcohol, beverages, electrical appliances, and cultural products
Mirror copperplate paper adhesive sticker is a high gloss sticker used for high-end multi-color product labeling, suitable for information labeling of drugs, food, edible oil, alcohol, beverages, electrical appliances, and cultural products
Aluminum foil adhesive sticker is a universal label for multi-color product labels, suitable for high-end information labels of drugs, food, and cultural products
Laser film adhesive sticker is a universal sticker for multi-color product labeling, suitable for high-end information labeling of cultural products and decorations

Storage of Adhesive Labels and Analysis of Common Problems
1. Storage Requirements for Adhesive Labels:
1. Adhesive labels should be protected from direct sunlight, moisture, sun, high temperature, and ultra-low temperature
2. Adhesive labels should not be mixed with flammable or volatile hazardous materials
3. When storing self-adhesive labels, they should be sealed with moisture-proof paper or film packaging. The rolls should be stacked vertically and stored flat, and the height of each board should not exceed 1m. The goods should be at least 10cm above the ground (with wooden boards)
4. On 23+ 2 ℃ and RH65± It can be stored for one year at a relative humidity of 5%, and some adhesives can last up to two years
II. Analysis of Common Problems with Adhesive Labels:
1. The selection of permanent and removable self-adhesive label paper can be generally divided into two categories based on the performance of the adhesive: permanent adhesive and removable adhesive. (Permanence is generally applied to electronic machinery, such as electronic tags, typically for mobile phone battery tags, and removability is generally applied to food, personal care, etc., such as wet wipe tags, fruit tags, clothing labels, etc.)
2. The surface of self-adhesive label paper may be labeled on various materials such as glass, metal, cardboard, and plastic due to the use of self-adhesive materials for processing labels. Plastic can be further divided into polyvinyl chloride and high-density polyethylene. Tests have shown that different sticker surfaces have a significant impact on performance, and we must pay attention to the material of the sticker surface when choosing
3. Intuitively speaking, the surface structure of the substrate for self-adhesive label paper requires a more viscous adhesive for rough label surfaces. Conversely, a less viscous adhesive can be chosen for this purpose
4. The surface shape of the adhesive label paper substrate. The surface of the label substrate can be divided into flat and curved surfaces. If the label surface has a certain curvature (such as the surface of a medicine bottle with a diameter less than three centimeters), it may require the surface paper to have good adhesion or adhesive with strong viscosity. It is also necessary to choose materials with better flexibility and tensile strength, such as PVC. The flat surface of the object being labeled is more suitable for a wider range of labeled materials. If the surface of the object being labeled is uneven, the material selection surface will be much smaller
5. The cleanliness condition of the surface of the adhesive label paper. Adhesive materials are suitable for label substrates with clean, dry, oil-free, and dust-free surfaces. When labeling, it is necessary to keep the surface of the object being labeled dry, oil-free, and dust-free in order to achieve better labeling results. If the surface cleanliness is poor, it will relatively affect the adhesion of the adhesive label paper

One minute to get to know you! What type of flame retardant adhesive label is used?
Flame retardant adhesive labels are a type of fire safety adhesive that is believed to not be ignited by fire. Actually, this understanding is inaccurate. The true meaning of flame retardant adhesive labels is graded, and the higher the grade, the higher the ignition point of the flame retardant adhesive label. Below, Jing Jie will take you to understand which type of flame retardant adhesive label is used
Firstly, the level of flame-retardant adhesive labels is also divided into flame-retardant V0 level and flame-retardant V2 level. There are various types of flame-retardant raw materials, including flame-retardant transparent PET adhesive, flame-retardant simulated silver PET adhesive, flame-retardant milky white PET adhesive, etc. Universal flame retardant PET adhesive is suitable for electronic devices, product labels, etc
Flame retardant adhesive labels provide you with flame retardant solutions, helping you significantly improve the safety of batteries. This series of products is composed of label materials, which consist of a flame-retardant layer and a flame-retardant adhesive. The flame-retardant layer is coated on the surface of the polyester. The overall structure meets the VTM-0 optimal fire rating specified in UL94 standard, which can effectively reduce the risk of fire. This type of signage material can better withstand -40 ° C; C to 149° The extreme temperature range of C not only provides insulation, but also does not produce toxic halogen smoke when ignited, and dripping water will not ignite accessory products. Used as a label around the battery, it helps reduce the risk of fire when the battery is overcharged, leaking, or overheated
Flame retardant adhesive labels not only effectively reduce safety risks, but also have strong compatibility in applications. The ultra-thin label design ensures a perfect fit between the battery and existing electronic devices, without affecting battery performance. In addition, this new label material is compatible with all common printing and processing techniques, bringing more freedom to design. It can not only be applied to lithium polymer batteries as edge labels for mobile devices, tablets, laptops, and other electronic products, but also to products such as airplanes and cars as coating labels for transformers, engines, and motors, providing reliable safety
Flame retardant adhesive label material is a type of fire-resistant adhesive, but it is only called differently. Flame retardant adhesive labels cannot be ignited by fire, so they are also called fire-resistant adhesive labels. Ordinary adhesive labels cannot prevent fire and are prone to burning with lighters, but flame-retardant adhesive labels cannot burn. There are also many types of flame retardant adhesive label materials, such as flame retardant bright white adhesive, flame retardant matte white PET adhesive, flame retardant transparent adhesive, flame retardant black PET adhesive, flame retardant matte silver dragon adhesive, flame retardant bright silver dragon adhesive, etc., mainly suitable for electronic product labels and other items
