Aluminum foil sticker is a kind of sticker film with aluminum foil as the main raw material, also called aluminum foil anti-slip sticker and golden sand sticker. The color is super white, in line with the original color requirements of inkjet printing, the ink absorption color is bright, can be printed and processed into various specifications of the text, patterns according to customer needs, the pattern and the text not easy fading, and is resistant to be yellowish. It is suitable for solvent, Eco-solvent, UV and latex ink printing methods.
Aluminum foil rough sticker has a certain degree of ductility, especially suitable for uneven walls or floors, such as rough walls, brick walls, potholes, asphalt floors, rough cement floors, and other kinds of need for non-slip steps, slopes. Aluminum foil floor sticker has a large friction coefficient, which can play the role of anti-slip in some crowded places, such as high-speed railways, subway stations, airports, etc., indoor floors can also be mostly used. It has a rough frosted surface with less water vapor permeability, which strengthens the water vapor barrier effect and water resistance. Compared with other surface coatings, the surface of aluminum foil is treated with a special anti-corrosion coating, which greatly improves the corrosion resistance.
The laminating process of aluminum foil anti-slip stickers refers to combining aluminum foil materials with other functional films or substrates through a specific process to form a composite material with specific properties and appearance. In this process, the choice of laminating process is directly related to the performance and quality of the final product. The laminating process of golden sand stickers mainly includes the following key steps:
Material selection and pretreatment: First, high-quality aluminum foil needs to be selected as the main raw material to ensure that it has good ductility and corrosion resistance. At the same time, according to the application requirements of the final product, select a suitable substrate (such as PET, PVC, etc.) and adhesive. At HANKER, this step benefits from the company's own raw material production lines such as PVC calendering film and release paper, which ensures the quality and supply stability of raw materials.
Coating and curing: The surface of aluminum foil needs special treatment, such as coating with anti-corrosion coating, to enhance its corrosion resistance. This step requires precise coating technology and efficient curing process to ensure that the coating is evenly and firmly attached to the surface of aluminum foil. HANKER's R&D center is equipped with advanced coating and curing equipment, which can accurately control the coating thickness and curing conditions to optimize the performance of the product.
Composite and pressing: The treated aluminum foil is laminated with the substrate through the composite equipment. In this process, the precision, temperature and pressure control of the composite machine are crucial, which directly affects the strength and lamination uniformity of the composite layer. HANKER uses advanced composite equipment and technology to accurately control various parameters in the composite process to ensure that the composite layer is firm and has no obvious bubbles.
Surface treatment: In order to give the aluminum foil anti-slip sticker a specific anti-slip property, it is usually necessary to roughen the surface of the composite layer, such as frosting. HANKER's R&D team has developed a unique surface treatment technology through continuous experiments and optimization, so that the aluminum foil sticker has excellent anti-slip effect while ensuring beauty.
In the selection of composite process, HANKER actively responds to the call for environmental protection and sustainable development, and is committed to promoting and applying solvent-free composite technology. Compared with traditional solvent-based lamination, solvent-free lamination technology has the following significant advantages:
Environmental protection: Solvent-free lamination technology does not use organic solvents, reduces the emission of volatile organic compounds (VOCs), and is more friendly to the environment and the health of operators. As a responsible corporate citizen, HANKER always integrates the concept of environmental protection throughout the entire process of product production and research and development.
Energy-saving: The solvent-free lamination process does not require drying and exhaust systems during the production process, has low energy consumption, and improves production efficiency. For large-scale enterprises like HANKER with two production bases, this means lower operating costs and higher resource utilization efficiency.
Product quality: Solvent-free lamination technology can provide higher composite strength and better bonding uniformity, which helps to improve the overall performance of aluminum foil anti-slip stickers, including weather resistance, chemical corrosion resistance and anti-slip performance. HANKER's R&D team has accumulated rich experience in solvent-free lamination technology and can customize high-performance aluminum foil anti-slip stickers according to customer needs.
Innovation and application: HANKER's investment and application in solvent-free lamination technology not only improves product quality, but also promotes the research and development of new products. For example, combining the characteristics of aluminum foil and the advantages of solvent-free composite technology, HANKER has successfully developed aluminum foil anti-slip stickers with a higher anti-slip coefficient, stronger waterproof performance and wider applicability, meeting the diverse needs of different fields.
