A new order have been finalized, The customer is from Malaysia.the quantity is 200,000 sheets for 100 micron polycarbontate laserable overlay film, the size is 290X500mm,for driver's license ,Holographic layers.The thickness and the size can be customized according to customer's requirement, because of different country with different size of the ID card, passport,and driving license.How does PC laserable film be applied to laser?
When the laser beam shines on the surface of the PC film, the high energy density of the laser beam will rapidly heat the surface of the material.As the temperature increases, the surface of the PC film begins to be heated, evaporated, melted, and may even result chemical reactions, oxidation.These thermal effects, chemical reactions and physical reactions work together to achieve the processing and transformation of the PC film surface.
In the laser process, it is necessary to precisely control the power, frequency, pulse width and other parameters of the laser beam, as well as the physical characteristics of the PC film thickness, hardness, thermal conductivity and so on.The precise control of these parameters is very important to achieve high precision and high efficiency laser machining.After the irradiation and processing of the laser beam, the surface of the PC film will form a specific pattern, text or mark.These marks have the characteristics of high definition, high contrast and high durability, and can meet the anti-counterfeiting and security requirements of ID cards, passports and other documents.
