The application of commonly used double-sided adhesive in die-cutting

In modern industrial production, die-cutting technology plays a crucial role in the application of double-sided adhesive in die-cutting technology. It is widely used in industries such as packaging, electronics, and automobiles to achieve cutting and assembly of various complex shapes. During the die-cutting process, the use of double-sided adhesive is an indispensable part. This article will provide a detailed introduction to several commonly used double-sided adhesives in die-cutting technology and their application characteristics in different scenarios. What is double-sided tape? Double sided adhesive refers to a product with adhesive applied on both sides of a layer of substrate. This type of material usually has good initial adhesion and holding force, which can effectively bond two objects tightly together. According to different needs, double-sided adhesive can be divided into various types such as hot melt, water-soluble, solvent, etc. The double-sided adhesive in die-cutting process plays a major role in the following aspects: 1 Fixing and pasting: By using double-sided adhesive, paper or other lightweight materials can be quickly and firmly fixed in specific positions, such as labels, stickers, etc. 2. Sealing and protection: Double sided adhesive can also be used for product packaging or to provide an additional protective layer to prevent damage to the product from moisture, dust, or other external factors. 3. Shock absorption and buffering: In some scenarios that require shock reduction, such as the protection of internal components of electronic products, double-sided adhesive with foam or sponge layers can be used to reduce vibration. 4. Conductive connection: For certain special double-sided tapes, such as conductive ones, they can achieve seamless connection between different materials while maintaining good conductivity. 5. Decoration and beautification: By utilizing the characteristics of double-sided adhesive, it can also achieve surface decoration effects on products, such as the attachment of metal foil, pearl film, etc. Common types and characteristics of double-sided adhesive for die-cutting 1 Hot Melt Adhesive: This is an adhesive that is in a solid state at room temperature and turns into a liquid when heated. Its advantage is fast curing speed, suitable for high-speed automated production lines; The disadvantage is that it has high temperature sensitivity and may have some odor issues. 2. Water soluble adhesive: This type of double-sided adhesive needs to be dissolved into a liquid state with water before being applied to the surface of the material. Its advantage lies in being environmentally friendly and odorless, suitable for food and other industries with high environmental requirements; But the operation is relatively cumbersome and the drying time is longer. 3. Solvent-based adhesive: This type of double-sided adhesive is a liquid state diluted in organic solvents, which can solidify into a solid state after the solvent evaporates. Its characteristics are strong adhesion and wide applicability; However, due to the presence of flammable and explosive solvent components, special attention should be paid to safety issues during storage and use. How to choose the appropriate double-sided adhesive? When choosing double-sided adhesive, the following factors should be considered: 1 Material compatibility: Ensure that the selected double-sided adhesive matches well with the material of the object being glued, in order to achieve the best bonding effect. 2. Working conditions: Depending on the specific working environment, such as temperature, humidity, etc., choose double-sided adhesive that is resistant to high temperature, low temperature, or has waterproof properties. 3. Cost effectiveness: Balance the relationship between budget and performance, and choose products with high cost-effectiveness. 4. Convenience of operation: If manual operation or frequent material replacement is required, easy to use double-sided tape should be selected. As a key component of the die-cutting process, the correct selection and use of double-sided adhesive directly affect the quality of the final product. Manufacturers should have a thorough understanding of the characteristics of various types of double-sided tape and their applicable scenarios in order to make the most suitable choice. With the continuous advancement of technology, the emergence of new double-sided adhesive will further enrich the application fields of the die-cutting industry, bringing more possibilities for innovation to the manufacturing industry.
