Corrugated cardboard is made into corrugated cardboard boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are one of the most widely used packaging products, and the amount used has always been the first of all kinds of packaging products. In addition to protecting commodities, facilitating storage and transportation, corrugated boxes also play a role in beautifying and promoting commodities. Attaching the exquisite logo can not only increase the added value of the product to a certain extent, but also facilitate the daily management of the product by the enterprise, which will do two things with one stone. Whether it is food, beverages, wine, food, meat, clothing, textiles, medicines, salt products, detergents, meters, electrical products, rubber products, or other products, corrugated boxes are usually used as the secondary and tertiary products of these products. In general, Oulance recommends using large-character inkjet printers to achieve the completion. The reasons for the choice are as follows: 1. The large-character inkjet printer adopts the principle of pressure-valve inkjet technology, which is easy to maintain, convenient to operate, and has a low failure rate. 2. The integrated chassis design enhances the protection level of the equipment and is suitable for working in different environments. 3. The nozzle is not easy to be clogged, and can be applied to a variety of inks (water-based, ketone-based, alcohol-based, etc.). 4. A variety of dot matrix effects can be adjusted freely, and the printing height can be arbitrarily selected. The exquisite logo effect enhances the added value of the product. Fifth, saving consumables is another advantage of large-character inkjet printers used in corrugated box identification, which can save a lot of coding costs for enterprises. Exquisite logos, high-level protection capabilities, simple and easy-to-use operating system have laid the foundation for the wide application of large-character inkjet printers on corrugated boxes. We firmly believe that large-character inkjet printers will be widely recognized by more users.
