As information technology continues to evolve, digital technology in different fields are playing an increasingly important role. The same is true in the packaging industry. Domestic Film Slitter technology through continuous improvement, in terms of speed, wide, control and other aspects of comprehensive performance significantly exceeded, digitization has also become an important direction for the development of domestic slitter.

      Many packaging material before being used in packaged goods, often after slitting - printing (or coating) - Composite - slitting process several times, but each time cutting slitting process in different ways, the common slitting ways: (1) cutting, cut the last procedure reserved for craft edge material, used for composite film materials processing; (2) clipped the wide roll cut into narrow Size multi-volume materials ; (3) sub-volume, Large diameter material will be divided into several small roll diameter roll material, the equivalent of rewinding and so on. These methods are sometimes mixed use, regardless of the kind of process, the material after cutting should reach the appropriate technical indicators: size requirements (refer slitting width and length dimensions of materials, etc.) and quality requirements (sheet flatness, surface quality, etc.).
    Manufacture and purchase of eligible cutting equipment not only to meet these specifications, you must also consider the following two factors: operational efficiency, including equipment, working speed, stability and ease of machine operation, etc.; economic performance, refers to devices Material scope of application, processing limit size, as well as the price of equipment, and energy consumption.

      With the continuous development of packaging technology and packaging grades improve, the packaged goods on the packaging material performance requirements have become increasingly prominent, there have been many materials with special properties, such as having a shading effect and high quality requirements of the aluminized surface, extending rate larger CPP film, having barrier properties of multi-material composite film. The continuous application of new materials, and promote the rapid development of the flexible packaging market. Market demand, as well as the development of special applications, the packaging material cut the increasingly high demand for cutting equipment requirements are more demanding. Other hand, with automated packaging equipment in the packaging industry in the gradual promotion, such as food packaging, cigarette packaging, etc. These automatic packaging machine after cutting quality of the material requires very picky, which gives slitter to the high-grade high-precision control brought a broad space for development.
    Previously used for domestic enterprises precision, high speed slitting mainly for foreign monopoly of a few manufacturers. Slitter on domestic developments in the industry have such a vivid metaphor: Early cutting machine structure is simple, the speed at 100m/min around and winding mechanical friction mode to manual control, people metaphor as "Phone machine "; later after some transformation, rewinding, etc. with the clutch control, single motor control traction and rewinding speed 200m/min below is called" simulation machine "; since new automatic high-speed cutting machine, the use of digital automatic control, the speed more than 300m/min, as in the field of modern communications "digital machines."

      With the technological capabilities of domestic enterprises to enhance, different manufacturers have introduced high-speed digital control cutting machine. Here are a few domestic manufacturers of high-speed digital control cutting machine, slitting glimpse of domestic technology, the latest progress.
