OPP CI Flexo Press

OPP CI Flexo Press refers to a central impression flexographic press specifically designed for printing on OPP (Oriented Polypropylene) film materials. This equipment is primarily used in the flexible packaging and label printing industry, enabling high-speed, multi-color printing on OPP (Oriented Polypropylene) film surfaces.

What is an OPP CI Flexo Press?

An OPP CI Flexo Press is a flexographic printing device employing a central impression drum structure. During printing, the OPP film adheres tightly to the central impression drum, and different colors are printed sequentially through multiple printing units, achieving high-precision color registration and stable print quality.

Because OPP film is thin and tension-sensitive, the CI (Central Impression) structure effectively ensures the stability of the material during the printing process, reducing errors and deformation.

Main Applications

OPP CI Flexo Press is primarily used for surface printing on plastic flexible packaging materials. Common applications include:

Food Packaging Printing: Such as snack bags, candy packaging, biscuit bags, and fast food packaging.

Daily Chemical Product Packaging: Shampoo, laundry detergent, and tissue packaging.

Label and Decorative Packaging: Product label and transparent packaging film printing.

Laminated Packaging Material Printing: Printing before OPP is laminated with materials such as PE, CPP, and PET.

Working Principle

The core structure of the OPP CI Flexo Press consists of a central impression cylinder and multiple flexographic printing units.

The basic process is as follows:

Unwinding System: The OPP film enters the equipment from the unwinding device.

Tension Control: The system maintains stable tension on the film.

Multi-color Printing: The film is applied to the central impression cylinder and printed color by color through multiple printing units.

Drying System: Rapid drying is performed after each printing unit.

Rewinding System: The printed film is rewound.

This structure ensures accurate color registration even during high-speed printing.

Key Advantages

1. High Registration Accuracy

The central impression cylinder keeps the film stable, reducing registration errors.

2. Suitable for Film Materials

Especially suitable for OPP, BOPP, PE, CPP, and other plastic films.

3. High Printing Speed

Industrial equipment typically reaches 200–400 m/min.

4. Stable Print Quality

Suitable for long-term continuous production.

5. Reduced Material Waste

Stable tension and registration system reduce scrap rates.

Common Printing Materials

This equipment is not only suitable for OPP but is also commonly used to print the following materials:

●BOPP film

●PE film

●CPP film

●PET film

●Aluminum foil composites

●Paper packaging materials

Therefore, it is very common in flexible packaging printing plants.

Technical Specifications

Characteristic

● The machine introduction & absorption of European technology / process manufacturing, supporting / full functional.
● After mounting the plate and registration, no longer need registration, improve yield.
● Replacing 1 set of Plate Roller (unloaded old roller, installed six new roller after tightening), only 20 Minute registration can be done by printing.
● The machine first mount plate, pre-trapping function, to be completed in advance prepress trapping in the shortest possible time.
● Maximum production machine speed up 200m/min, registration accuracy ±0.10mm.
● The overlay accuracy does not change during lifting running speed up or down.
● When machine stop, Tension can be maintained, the substrate is not deviation shift.
● The whole production line from the reel to put the finished product to achieve non-stop continuous production, maximize product yield.
● With precision structural, easy operation, easy maintenance, high degree of automation and so on, only one person can operate.

FAQ

1. What materials can an OPP CI Flexo Press print besides OPP film?

It is mainly designed for OPP film printing, but it can also print on other flexible packaging materials such as BOPP, PE, CPP, PET film, laminated films, and paper used in packaging applications.

2. What industries commonly use an OPP CI Flexo Press?

This type of flexographic printing machine is widely used in industries such as food packaging, snack bags, candy wrappers, daily chemical packaging, labels, and flexible plastic packaging production.

3. What is the typical printing speed?

Most modern OPP CI Flexo Press machines operate at speeds ranging from 200 m/min to 400 m/min, depending on the machine configuration, number of colors, and printing material.

4. How many colors can an OPP CI Flexo Press print?

It is usually available in 4-color, 6-color, 8-color, or 10-color configurations, allowing manufacturers to achieve high-quality multi-color packaging printing.

5. Why choose a CI flexo press for OPP film printing?

A CI (Central Impression) flexo press keeps the OPP film tightly wrapped around a central drum, which helps maintain accurate color registration, stable tension control, and consistent print quality, especially for thin film materials.

6. Is it suitable for high-volume production?

Yes. Due to its high-speed operation, stable printing performance, and efficient drying systems, the OPP CI Flexo Press is ideal for large-scale flexible packaging production.

7. What should buyers consider when choosing an OPP CI Flexo Press supplier?

Buyers should evaluate factors such as machine quality, manufacturer experience, technical support, customization capability, and after-sales service when selecting a CI flexo printing machine supplier.

8. Can be customized for different packaging requirements?

Yes. Many professional manufacturers offer customization options, including printing width, number of colors, drying systems, automatic registration systems, and tension control systems to meet different production needs.
