OPP CI Flexo Printing Machine

The OPP CI Flexo Printing Machine is a central impression (CI) flexographic printing device specifically designed for OPP (oriented polypropylene) films. This machine adopts a central cylinder structure to ensure stable wrapping of the film material, achieving high-precision, multi-color flexographic printing in high-speed production environments. It is widely used in the packaging industry.

Working Principle

The OPP CI flexo printing machine employs a central impression cylinder structure (CI Structure). Its core workflow includes:

Unwinding System: The OPP film is stably unwound via an automatic tension control device.

Ink Supply System: An anilox roller precisely controls the ink transfer amount, ensuring uniform printing.

Flexographic Printing Units: Each color has an independent printing unit, transferring image and text using a flexible plate.

Central Impression Drum: All printing units are arranged around the central cylinder, allowing for multi-color overprinting on the same cylinder, improving printing accuracy.

Drying System: Hot air or infrared drying ensures rapid ink drying.

Rewinding System: After printing, the material is automatically rewound, maintaining stable tension.
