Can a Unit-Type Flexo Press be Used for Printing on Plastic Films?

Yes, a unit-type flexo press can be used for printing on plastic films. In this article, we will provide a basic definition and product features of the unit-type flexo press. We will also discuss its advantages, working principles, application scenarios, how to choose, possible problems during use and maintenance, and introduce EVER-POWER, a professional manufacturer of flexo presses.

Definition and Product Features

A unit-type flexo press is a type of printing press used in the flexographic printing process. It is designed with modular units that can be combined and configured according to specific printing requirements. Each unit of the press consists of various components, such as a plate cylinder, anilox roller, inking system, and impression cylinder, which work together to transfer ink onto the printing substrate.

Advantages

1. Versatility: Unit-type flexo presses offer great flexibility and versatility in printing applications.
2. High Printing Quality: Flexo presses have made significant advancements in recent years, achieving excellent print quality comparable to other printing methods.
3. Speed and Efficiency: Unit-type flexo presses are known for their high production speeds.
4. Cost-Effectiveness: Flexo printing, including unit-type flexo presses, is generally considered a cost-effective solution for medium to high-volume printing.
5. Wide Substrate Compatibility: Unit-type flexo presses are compatible with a variety of substrates, including plastic films, labels, and flexible packaging materials.
6. Environmentally Friendly: Water-based and UV-curable inks are commonly used, which have lower volatile organic compound (VOC) emissions compared to traditional solvent-based inks.
7. Inline Finishing Options: Unit-type flexo presses can be equipped with various inline finishing options, such as laminating, die-cutting, embossing, and varnishing.
8. Continuous Innovation: The flexographic printing industry is continuously evolving, with ongoing advancements in technology, materials, and processes.

Working Principles

1. Plate Cylinder: The unit-type flexo press has a plate cylinder with a flexible printing plate attached to it.
2. Inking System: Anilox rollers transfer ink to the plate cylinder.
3. Impression Cylinder: The impression cylinder receives the substrate to be printed.
4. Drying System: After the ink is transferred to the substrate, a drying system is employed to evaporate solvents or cure the ink.
5. Repeatable Units: Unit-type flexo presses are designed with repeatable units, which can be combined to achieve multi-color printing.

Application Scenarios

1. Flexible Packaging: Unit-type flexo presses are commonly used for printing on plastic films and laminates.
2. Corrugated Packaging: Flexo presses are widely employed for printing on corrugated cardboard used in packaging boxes and containers.
3. Labels and Tags: Flexo presses are preferred for printing labels and tags used in various industries, including retail, logistics, and manufacturing.
4. Folding Cartons: Unit-type flexo presses are utilized for printing on folding cartons.
5. Paper Products: Flexo presses are suitable for printing on a wide range of paper products.
