Plastic Film Printing Machine consists of an unwinding unit, a guide system, a plate roller transmission structure, a tension control system, a printing unit, a drying system and a winding unit. It is equipped with a high-definition touch screen, a color registration control system and an optional defect detection module. It is a high-precision roll-to-roll printing device designed for printing patterns or text on the surface of various plastic substrates.

1. Highly compatible ink path system to meet the needs of various types of ink materials

Plastic Film Printing Machine supports both water-based ink and ink systems. The printing channel can be flexibly switched according to process requirements to adapt to different environmental standards and color saturation requirements. Through the constant pressure ink supply system, the ink flow is stable, which is suitable for high-end printing operations requiring high ink uniformity.

2. Accurate overprint control and excellent color consistency

Plastic Film Printing Machine adopts a fully automatic overprint servo system, combined with a closed-loop deviation correction module imported from Germany, to achieve an overprint error of ≤±0.1mm. Whether running at high or low speed, it can ensure accurate color registration and is suitable for the production of high-quality pattern printing films.

3. Low-tension transmission system, suitable for ultra-thin material printing

Plastic Film Printing Machine uses digital tension closed-loop control, and the minimum tension control range can reach 1.5N, which is suitable for tension-sensitive materials such as breathable film, ultra-thin PE film, etc., to avoid material stretching deformation or pattern offset problems.

4. Energy-saving air drying system to improve efficiency

The drying area adopts an air-energy hot air circulation system with high drying efficiency and low energy consumption. Each color group is equipped with an independent temperature-controlled air duct with an adjustable temperature range of 50~120°C, which is suitable for the drying requirements of different ink materials to ensure that the color is stable and non-sticky after printing.

5. Automatic material connection and replacement system to improve continuous production efficiency

The unwinding and rewinding parts support automatic rewinding and automatic cutting, and the system response time is<1 second="">

6. Special film unfolding device to ensure printing accuracy

The multi-head unfolding roller structure specially developed for PE and breathable film can adjust the film path according to the softness of the film material, improve the material flatness and printing alignment accuracy, and is one of the few printing machines on the market that can stably handle elastic materials.

1. Disposable Diaper Film Printing Factory in Istanbul, Turkey

The factory provides baby diaper base film for P&G Procter & Gamble Group. It uses the Plastic Film Printing Machine for breathable PE film color printing, with an annual output of more than 5,000 tons. The Plastic Film Printing Machine has stable operation and high color saturation, helping customers enter the European mid-to-high-end maternal and child products market.

2. Pet pad printing center in Gurgaon, India

Plastic Film Printing Machine is used for printing film materials for pet absorbent pads in India. The main materials are CPP and PE composite films. The customer uses the equipped with a 7-color ink printing system and equipped with an online defect detection device. The cooperative brand is Heads Up For Tails, the leading brand of Indian pet products.

3. Inner packaging film printing line for sanitary napkins in Curitiba, Brazil

Brazilian customers introduced the model for the production of PE/PAPER composite film printing, which is specially supplied to Kimberly-Clark's Brazilian factory for female care products. The Plastic Film Printing Machine provides high width and high-speed operation capabilities to meet the needs of fast delivery of large orders.

4. Ulsan Medical Packaging Film Production Base in South Korea

Plastic Film Printing Machine is installed on the PE medical packaging film production line to customize pattern printing for CJ Healthcare. It uses a 10-color ink configuration, is environmentally friendly and low-odor, and meets the Korean medical film packaging hygiene standards to ensure that the printed pattern is clear and does not produce residual odor.

1. Printing roller cleaning and scraper replacement

After daily shutdown, the printing plate roller should be thoroughly cleaned with professional solvent to prevent the ink from drying. The scraper is recommended to be replaced every 200 hours of operation to ensure uniform scraping and prevent ink accumulation or leakage.

2. Calibration of tension control system

The tension sensor needs to be calibrated once a month through the software interface, and the servo motor drive needs to be checked for synchronization to ensure stable feeding under low tension conditions, especially for easily deformed substrates such as breathable membranes.

3. Drying system filter cleaning and air duct inspection

The air energy drying system needs to clean the filter every 500 hours of operation to prevent dust clogging and affect the hot air efficiency. At the same time, regularly check whether the error of the air duct temperature control probe exceeds the limit to ensure consistent temperature distribution.

4. Lubrication and inspection of automatic material connection and change module

It is recommended to lubricate and check the pneumatic knife and push-pull guide rail in the material connection and change system every 1,000 rolls to avoid action jams and material change failures, while maintaining the sensitivity of the sensor.

5. Diagnosis of the operation of the overprint servo system

Perform a linkage test of the servo motor and the overprint system every quarter to ensure that the software error compensation value is within ±0.1mm. If deviation is found, it should be recalibrated in time through the operating system to maintain high-precision overprint standards.
