Screen printing of metal packaging is a kind of special packaging printing. It is a screen printing method that uses a hard material unique to metal packaging products as a substrate. The main printing materials are tinplate (tin-plated steel sheet), chrome-plated steel sheet, Galvanized thin steel sheet, cold rolled carbon thin steel sheet, hot rolled carbon thin steel sheet, etc. There are also special packaging materials using aluminum plate, stainless steel plate and other materials. Metal packaging screen printing is an integral part of the production process of metal packaging. It is the sign of the packaging content and contains certain advertising ingredients. Therefore, in order to arouse the consumer's desire to buy and increase the sales value of the goods, as a means of promotion, novel decoration design and exquisite printing should be carried out. In this way, the metal packaging screen printing becomes more important. 1. Performance characteristics of screen-printed metal packaging 1. Physical properties and characteristics of screen printed metal materials Metal packaging materials generally have good heat transfer and electrical conductivity, high mechanical strength, and are ideal materials for metal packaging. Because of its good ductility, it is easy to cut, stamp, bend, and stretch. More importantly, metal packaging materials can withstand all kinds of watches and processing, and can meet the decorative functions of various packaging. 2. Technical requirements of screen printing on metal materials â‘ Straightness: The metal sheet must not be warped â‘¡Surface roughness: The surface of the metal sheet should be free of mechanical scratches, scratches, unevenness, rough stripes and other surface roughness. â‘¢ Cleanliness: The printed surface of the metal packaging should be clean and free from oil, dirt, water and other unclean phenomena. 3. Printing adaptability requirements â‘ Good processability of metal packaging materials and diversity of shape design Metal packaging materials have good mechanical properties and processing and forming properties. Metal packaging containers can achieve novel and unique manufacturing designs and produce various shaped barrels, cans, boxes and other packaging containers to achieve the purpose of beautifying commodities and improving the competitiveness of commodities. . â‘¡ Bright colors, rich levels, and good visual effects If the metal packaging is tin plate, because its surface is tin plated, it has a glittering color effect, and then after the background color printing, the printed graphics are more vivid. For tin-free steel plates or other metal materials, after surface treatment and painting, special flash effects can also be reproduced after screen printing. â‘¢Conducive to the unity of the use value and artistry of the commodity The good performance of metal packaging materials and the good wear resistance and durability of screen printing inks not only create conditions for the realization of unique styling design and exquisite screen printing, the decoration of metal packaging surfaces not only makes the packaging more beautiful, Moreover, the value of the metal packaging itself can be greatly improved and the durability and maintainability of the product can be improved, which can better reflect the unity of the use value and the artistry of the product. â‘£An important means to reduce costs The use of screen printing has changed or simplified the production process of certain metal packaging products (such as steel drums, etc.), reducing production costs. For the above reasons, the screen printing of metal packaging has developed rapidly in recent years. Second, the design features of metal packaging screen printing
