Characteristics

Thermo-adhesive: It is solid and non-sticky at room temperature. When heated to a specific temperature (such as the melting point of EVA hot melt adhesive film is 70-120℃, and the melting point of TPU hot melt adhesive film is 100-180℃), it melts quickly and shows good viscosity. It can tightly bond a variety of materials and solidify after cooling to form a stable connection.

Environmental protection characteristics: It does not contain solvents and does not emit volatile organic compounds (VOCs). It is environmentally friendly during production and use, in line with current environmental protection standards and trends, and has significant advantages in industries with strict environmental protection requirements such as food packaging and medical supplies manufacturing.

Fast curing: Once cooled, the curing process can be completed in a short time, usually within a few seconds to a few minutes (such as in the application of the electronics industry, it can be initially cured within a few seconds), which greatly improves production efficiency and is suitable for large-scale and high-efficiency production scenarios, such as the rapid assembly of automotive interior parts.

Good flexibility: Some hot melt adhesive films, such as TPU, still have a certain flexibility after curing, can adapt to the deformation and bending of the bonded materials, and will not cause cracking at the bonding point due to slight deformation of the material. They perform well in the manufacture of wearable devices and flexible electronic products.

Wide applicability: It has good bonding performance for a variety of materials such as metal, plastic, paper, wood, fabric, leather, etc. For example, it can bond wood and metal parts in furniture manufacturing, and can bond fabric and leather decorative parts in clothing production.

Chemical resistance: It has a certain chemical corrosion resistance and can resist the erosion of common acids, alkalis, organic solvents, etc. When used in chemical equipment sealing, outdoor product protection and other fields, it can maintain stable bonding performance in complex chemical environments.

Precise and controllable: It can be punched into precise shapes and sizes, which is convenient for precise glue supply and application on automated production lines. It can also accurately control the thickness of the adhesive film according to different needs (common thickness is 0.05-0.25mm) to ensure the consistency and stability of the bonding quality.

Application areas

Clothing and shoe material industry

Clothing production: used for bonding various embroidery, printed trademarks, embroidered badges, etc. with the main body of clothing; realize the composite of textiles, clothing fabrics and leather materials, and enhance the texture and durability of clothing; used as bonding medium in heat transfer printing, hot diamond, heat transfer, flocking and other processes to ensure that patterns and decorations are firmly attached; make seamless underwear, clothing zipper cloth, shoe tongue label, etc., to improve the wearing comfort and appearance of clothing.

Shoe material processing: realize the seamless bonding of sandwich mesh cloth, leather, microfiber and other materials on the upper, replace traditional sewing, and improve the overall waterproofness and appearance of shoes; used for bonding the sole and the upper, enhance the connection strength between the sole and the upper, and adapt to the durability requirements of shoes in different sports scenes.

Electronics Industry

Electronic product assembly: hot pressing and bonding of plastics (such as ABS, PC, PET, PP, PE, PVC, resin boards, fiberglass boards, etc.) and metals. For example, in the mobile phone industry, it is used to fix the mobile phone shell and the internal metal frame and electronic components; in tablet computers, laptops and other products, it is used to bond the display screen and the frame, the keyboard and the body to ensure the stability of the product structure.

Fixing of electronic components: Provide stable fixation for electronic components (such as chips, capacitors, resistors, etc.) to prevent them from shifting or being damaged due to vibration and collision during circuit board assembly, transportation and equipment operation, and ensure the stability of electronic product performance.

Electronic equipment protection: Protect electronic equipment from light, electromagnetic, high temperature, humidity, dust accumulation and other factors. For example, in some outdoor electronic equipment, hot melt adhesive film can be used for sealing protection to prevent water vapor and dust from entering the equipment.

Packaging industry

Paper packaging: used for edge sealing and sealing of cartons and paper boxes to make the packaging more solid; bonding labels to the packaging surface to ensure that the labels are not easy to fall off, and at the same time, it can protect the labels from water, moisture and UV rays; in the production of gift boxes, folders, etc., it can achieve the bonding of paper and paper, and paper and other decorative materials.

Plastic packaging: used for heat sealing of plastic film and plastic film, plastic film and plastic container, such as heat sealing of food packaging bags; in the connection of plastic pipes, it is used as a medium for hot melt connection to ensure the sealing and strength of pipe connections.

Flexible packaging: in the compounding of flexible packaging materials, such as compounding aluminum foil and plastic film, it can improve the barrier properties of packaging and extend the shelf life of products.

Automobile industry

Automobile interior: bonding automobile molded ceiling lining, carpet, seat cushion, interior audio shell and other parts to improve the overall beauty and comfort of the interior; fixing various decorative strips and plastic parts in the automobile interior to prevent them from loosening due to vibration during vehicle driving.

Automotive exterior: used for pasting car body decorative strips, headlight covers, rearview mirrors and other parts, enhancing the connection strength between exterior parts and the car body, and improving the integrity and beauty of the car's appearance.

Home and building materials industry

Furniture manufacturing: to achieve the bonding of wood and wood, wood and metal, wood and plastic and other materials, such as when making furniture such as tables, chairs, cabinets, etc., used to connect various parts; pasting decorative panels and edge banding strips on the surface of furniture to improve the appearance quality and service life of furniture.

Building decoration: used for pasting wall decoration materials (such as wallpaper, wall cloth) and walls to ensure that the decorative materials are flat and firm; in the installation of ground materials, such as the laying of PVC floors and wooden floors, it can assist in fixing and enhance the connection stability between the floor and the base layer; in the installation of doors and windows, it can bond door and window sealing strips to improve the sealing performance of doors and windows.
