Flexo In Corrugated Boxes Industry

Flexo in foreign countries has been developing quickly, especially in packaging and printing, the U.S. flexo packaging printing market accounted for 75%, Europe 35% of the total print share with flexo way, and the market share also expanding. Relatively speaking, our flexo late start, but the flexo process and by virtue of its unique characteristics, has cut a striking figure in the packaging printing industry, is being promoted and universal.

    Flexo corrugated box in the application characteristics

    Today, growing awareness of environmental protection, resource conservation concern, flexo is considered in many varieties, small batch, short cycle, low-cost printing of ordinary cardboard boxes and a widely used printing. Flexo printing in the corrugated box has the following advantages.

    (1) environmental protection and good. Flexo line with international environmental requirements of the water-based ink, non-polluting production process, printing the pass rate has greatly improved. Plate can be less volatile when the environmental solvents and recovery of waste solvents using the recovery will be pollution to a minimum.

    (2) loss, short period and high efficiency. Flexo usually reel-type material, format can be as narrow as 2.5cm, width from a few meters. Printing costs, the flexo offset lower than 15%; paper consumption, the flexo paper scrap rate of 1% and 5% offset; also can be set flexo printing, die cutting, polishing and other functions into one, flexo corrugated boxes production process offset printing processes less than 2 ~ 3, therefore, the printing cycle, flexo 2 to 3 days to complete the live parts, and offset printing needs 7 to 8 days to complete, and the need to offset with post-mounted back machine, cutting machine, polishing machines and other equipment, increased investment, in short, flexo printing can greatly shorten the cycle, low energy consumption, low cost, allowing users in a highly competitive market leading position.

    (3) ease of operation, noise, no pollution. Compared with other presses, flexo machine structure is relatively simple, so easy operation, easy maintenance, operation of the machine when the transmission noise, and water-based ink used in environmental pollution.

    (4) no fly ink phenomenon. Flexo water-based ink used in the pollution to the environment, coupled with a reverse doctor blade, will not produce the phenomenon of flying ink, printing does not fade after the corrugated box, no de-inking.

    (5) to make corrugated board compression, bearing pressure increased. Flexo corrugated board, after high temperature treatment and hot glue bonding, the compressive strength is superior to offset the cold plastic composite, and corrugated boxes through the flexo, UV, after polishing, with wear, dirt, moisture-proof function.

    Although flexo machine has many advantages, simpler structure than the offset press, but changes in flexo many factors involved, such as plates, anilox, ink, embossing structure Dengjun in the flexo process interact with each other constraints. Therefore, a high technology content flexo process, practitioners must master the plate-making process from pre-press to printing process related knowledge. In addition, offset, gravure printing, as a relatively mature technology, there are some generally accepted norms or standards formulated by the state to follow, but there is no universal flexo criteria guiding the process parameters or specifications, it requires more employees must have a solid knowledge accumulation.

    Flexo printing directly

    Direct printing with flexo corrugated boxes manufacturing process for the corrugated cardboard direct flexo plate production → → → die bonding slotted nail me. The biggest advantage of direct printing flexo is able to connect the production, that is, printing, polishing, cutting, slotting, sticky boxes, packing can be done on a machine. Just a new corrugated box plants and corrugated board production line configuration flexo machine can be put into production, and use pre-printed offset and the way you need multiple devices.

    Packaging market in China there is a certain degree of over-packaging, hampered flexo technologies. But there are still some factors that would promote flexo technology in the corrugated box industry promotion. Frequent revision or version, such as increased product directly in the corrugated board flexo printing method has the speed, low cost, good quality advantages; market towards intensive, large-scale development, customer inventory reduction, increasing the packing objects can be directly used to, flexo customers with a faster speed of response.
