Background
Laser films generally employ computer dot matrix lithography, 3D true color holographic techniques, multiple and dynamic imaging techniques, and the like. The holographic image with rainbow dynamic and three-dimensional effect is transferred to PET, biaxially oriented polypropylene film, PVC or coated base material by mould pressing, and then the surface of commodity package is made to obtain a certain laser effect by means of compounding, thermoprinting, transferring and other modes. The laser packaging is a subdivision industry in the packaging industry, and has been rapidly developed in recent years, and compared with other products in the packaging industry, the laser packaging material not only has novel and bright appearance effect, but also has a high-technology anti-counterfeiting function, and is called as the forefront technical product in the world packaging printing industry. The application field of the laser material is very wide at present, and the laser material is rapidly popularized in industries such as food, medicines, daily chemical products, cigarettes and wines, clothing, gift packages, decorative materials and the like. From the technical level, the anti-counterfeiting laser film product currently applied to the fields of trademark printing and tobacco bale printing belongs to a high-end product in the industry, and the production process relates to a plurality of technical links such as laser anti-counterfeiting plate making, mould pressing, coating, transferring and the like, and the product has higher added value. The laser device is also widely applied to tobacco packaging, food packaging, daily necessities packaging, such as moon cake boxes, toothpaste boxes and the like, and the application of the laser technology in the fields is more and more.
Most of laser films used in the market at present are laser transfer aluminized films, local aluminized laser positioning is transferred to a position required by surface printing films, and transferred patterns can be words or patterns and lines. The PET laser transfer paper manufactured by the method has been widely applied to the market of tobacco packages. Development work of aluminum foil replacement by aluminum foil to reduce aluminum consumption and laser plastic film replacement by transfer laser to reduce white pollution is carried out, and good results are obtained. The material is not only a requirement for development of environmental protection situations, but also a material with wide development space, and can be greatly popularized in a plurality of industries, and has very broad development prospect.
