Self-adhesive backing paper, as an essential component of self-adhesive labels, plays a crucial role in holding the adhesive, protecting the label, and assisting in the labeling process. Its material, thickness, color, and performance directly affect the die-cutting accuracy, labeling efficiency, applicable scenarios, and cost control of the labels. Currently, the most widely used self-adhesive backing papers on the market are mainly divided into three categories: graflex backing paper, laminated backing paper, and PET backing paper. These three types have significant differences in color, labeling compatibility, advantages and disadvantages, and thickness specifications, and are suitable for different production needs and usage scenarios.
The selection of self-adhesive backing paper mainly revolves around five key dimensions: color, label compatibility, advantages and disadvantages, thickness specifications. In addition, a comprehensive judgment needs to be made based on production efficiency and cost budget. The differences in characteristics among various types of backing papers stem fundamentally from the differences in their production materials and processes - Grafix backing paper is made from wood pulp and undergoes special treatment; laminated backing paper uses original paper as the base and has PE film coated on the surface; PET backing paper is made from polyester film and has excellent physical properties. The differences in processes and materials directly result in the differentiation of these three types in various characteristics. The core characteristics of each type of backing paper will be introduced in detail below.
Glasindi base paper is currently the most widely used and cost-effective type of base paper in the self-adhesive industry. It is made from high-quality wood pulp and processed through super lamination. Its core feature is low cost and suitability for low-speed labeling. It is widely used in various conventional self-adhesive label scenarios, and is particularly suitable for enterprises that are sensitive to costs and have low requirements for labeling speed.
In terms of color selection, the Grasind base paper comes in three colors: white, blue, and yellow. These colors can meet the adaptation requirements for different labels. Among them, white is the most versatile color, suitable for most conventional labels. It presents a clean visual effect, making it easy to observe the label patterns and text. Blue and yellow are mostly used in special scenarios, such as differentiating labels of different specifications and enhancing label recognition. They are suitable for batch production for classification management and reducing confusion.
In terms of label adhesion compatibility, Graisin base paper is mainly suitable for low-speed automatic labeling scenarios. Due to its thin texture and moderate stiffness, it can maintain a good flatness during low-speed labeling, and is less likely to encounter problems such as paper jamming or paper breakage. It has high alignment accuracy and is suitable for small automatic labeling machines and semi-automatic labeling equipment, and is widely used in regular labeling needs such as food, daily necessities, and office labels. However, it should be noted that it is not suitable for high-speed automatic labeling. During high-speed operation, it is prone to tearing and deformation, which affects the labeling efficiency.
In terms of advantages and disadvantages, the Glasinstaff paper has outstanding features: Firstly, it is thin in texture and light in weight, which makes it easy to store and transport. At the same time, it can reduce the overall thickness of the label, making it more aesthetically pleasing after application and occupying less space; Secondly, it has a high cost performance. The raw material cost is low, the production process is mature, and the market price is generally lower, which can effectively control the production cost of enterprise labels and is suitable for bulk purchasing. Its limitations mainly lie in that it is not suitable for single use. Due to its thin texture, when a single sheet is peeled off, it is prone to damage and curling, and it is difficult to achieve precise manual labeling. It is more suitable for batch labeling scenarios in roll form.
In terms of thickness specifications, the common thicknesses of Grasinc base paper are 40g, 50g, 60g, 70g, and 80g. Different thicknesses are suitable for different label requirements. The thicknesses ranging from 40g to 50g are considered thin models, suitable for lightweight labels such as small food labels and office stickers; the thicknesses ranging from 60g to 70g are the standard thicknesses, suitable for most general labels, balancing both rigidity and lightness; the thickness of 80g is considered thick, with better rigidity, suitable for labels with complex die-cutting and larger sizes, which can reduce damage during die-cutting.
The laminated base paper is made by using ordinary base paper as the base and coating a layer of PE (polyethylene) film on the surface. It is a self-adhesive base paper with multiple colors and thicknesses that are suitable for adaptation. It is mainly used in non-automatic labeling scenarios and has a relatively higher price. It is suitable for label requirements with specific requirements for the thickness and color of the base paper.
In terms of color selection, the laminated base paper mainly comes in three colors: white, yellow, and kraft paper. These colors are suitable for different label styles and usage scenarios. The white laminated base paper is clean and tidy, suitable for regular colored labels; the yellow laminated base paper has high visibility and is suitable for distinguishing special-purpose labels; the kraft paper laminated base paper has a natural vintage texture, is environmentally friendly and has good toughness, and is suitable for eco-friendly labels, gift labels, etc., enhancing the product's quality.
In terms of label adhesion compatibility, the core feature of the laminated base paper is that it is not suitable for automatic labeling. Due to the PE film coating on its surface, the texture is soft and the tensile strength is insufficient. During the operation of the automatic labeling machine, it is prone to problems such as slipping, curling, and paper jamming, which cannot ensure the accuracy and efficiency of labeling. Therefore, it is mainly suitable for manual labeling scenarios, such as manual label production, small batch labeling, and labeling of irregular shapes, and is suitable for scenarios where the requirements for labeling speed are not high.
In terms of advantages and disadvantages, the advantage of laminated base paper is that it offers a wide range of thickness options, allowing for the selection of either thin or thick versions based on the requirements. The thick base paper has good toughness and is less prone to damage, making it suitable for labels with complex die-cutting and large sizes. Additionally, it comes in a variety of colors, meeting the needs of different styles of labels. However, its limitations are quite obvious: first, the price is relatively high, as the laminating process increases production costs and the price is higher than that of graffinized base paper; second, it is not suitable for automatic labeling and cannot meet the requirements of batch and high-speed production; third, the thin laminated base paper lacks sufficient stiffness, and it tends to curl when manually applied, affecting the accuracy of labeling.
In terms of thickness specifications, the common thicknesses of laminated base paper are 70g, 90g, 120g, 140g, and 170g. The thickness range is quite wide, suitable for different scenarios. The thicknesses ranging from 70g to 90g are thin models, suitable for small-scale manual label application; the thicknesses ranging from 120g to 140g are regular thicknesses, balancing toughness and portability, suitable for most manual label requirements; the thickness of 170g is thick, with extremely strong toughness and not prone to damage, suitable for large labels, irregular labels, as well as labels that need to be repeatedly handled, stored.
PET base paper is a self-adhesive base paper made from polyester film. Also known as polyester base paper, its core characteristics are transparency, compatibility with high-speed automatic labeling, high cost-effectiveness, and excellent physical properties. It is suitable for scenarios with high requirements for labeling efficiency and adhesive uniformity, and is widely used in high-end labels and batch high-speed production scenarios.
In terms of color, the PET base paper is mainly transparent. This is one of its most prominent features. The transparent base paper can clearly show the glue condition on the back of the label, making it easy to check the uniformity of the glue. At the same time, after being adhered, it does not affect the aesthetic appearance of the label itself. It is especially suitable for transparent labels and high-end color labels, which can enhance the overall texture of the label and avoid the color of the base paper from blocking the label pattern.
In terms of label adhesion, PET base paper is mainly suitable for high-speed automatic labeling scenarios, which is its core advantage. Due to its tough texture, high stiffness, and smooth and flat surface, it can maintain a stable flatness during the operation of high-speed labeling machines, and is less likely to experience tearing, deformation, or paper jamming problems. The labeling accuracy and efficiency are high, making it suitable for large-scale batch high-speed production in industries such as beverages, cosmetics, electronic products, etc., which require large-scale labeling.
In terms of advantages and disadvantages, the PET base paper has very significant benefits: Firstly, it has a high cost-performance ratio. Although the raw material cost is higher than that of the gelatin base paper, it has a long service life, high labeling efficiency, and can reduce the overall cost of long-term production. Secondly, the adhesive level is high, the surface is smooth, which enables the adhesive to be evenly distributed, improving the adhesion strength of the label and avoiding problems such as uneven adhesive application and curling. Thirdly, it is tough and not prone to damage or tearing, making it suitable for cutting complex labels. At the same time, it is convenient for storage and transportation. Its limitations mainly lie in the difficulty of die-cutting. Due to the strong toughness of the PET material, special equipment and tools are required for die-cutting, making the die-cutting process more difficult and with higher die-cutting accuracy requirements, which increases the production difficulty to a certain extent.
In terms of thickness specifications, the common thicknesses of PET base paper are 30g, 36g, 50g, 75g, 100g, and 150g. There is a wide range of thickness options to meet different needs. The 30g-36g thickness is for thin models, suitable for lightweight high-end labels such as cosmetic labels; the 50g-75g thickness is the standard thickness, suitable for most high-speed labeling requirements, balancing stiffness and lightness; the 100g-150g thickness is for thick models, with greater stiffness and toughness, suitable for large labels, high-speed labeling scenarios, and labels with high requirements for base paper strength.
In summary, Glashaden paper is suitable for low-speed automatic labeling in scenarios with limited budgets; laminated paper is suitable for manual labeling in scenarios with specific color and thickness requirements; PET paper is suitable for high-speed automatic labeling in scenarios with high demands for adhesive uniformity and label texture. Enterprises should select the appropriate self-adhesive base paper based on their labeling methods, production efficiency, cost budget, and label requirements, making a comprehensive judgment and choosing the most suitable self-adhesive base paper that can not only ensure labeling quality but also control production costs.
