Changhong Flexo Printing Machinery has developed its stack type flexo printing machine as a practical solution for flexible packaging manufacturers looking for stable printing performance, flexible production configurations and efficient operation across different substrates.

Designed for a wide range of printing applications, the machine can be used for plastic film, paper, nonwoven materials and other flexible packaging substrates. It is particularly suitable for applications such as plastic bags, paper bags, packaging film and PP woven bags, where reliable material handling and consistent print quality are essential.

The stack type flexo printing machine can be configured with multiple printing units to meet different production requirements. Changhong provides configurations from 4 to 8 colors, with printing widths and other specifications customized according to the customer’s application and production needs.

With a maximum printing speed of up to 200 m/min and register accuracy of approximately ±0.15 mm, the machine is designed to provide stable performance during continuous production. Independent servo motors are used for the printing units, helping operators maintain consistent printing performance across different jobs.

One of the key advantages of the stack configuration is its flexibility. Each printing unit is arranged independently, allowing the machine to handle different printing requirements while maintaining a relatively straightforward machine structure. This makes the press suitable for converters that need to produce different types of packaging products on the same machine.

Designed for Flexible Packaging Applications

Material handling is an important consideration when printing flexible substrates. During continuous operation, plastic films and other lightweight materials can be affected by tension changes, material deviation and stretching.

Changhong’s stack type flexo printing machine incorporates a controlled web feeding and tension system to help keep the substrate stable during printing. This supports consistent ink transfer and registration, particularly during longer production runs.

The machine can be used with materials including PE, PP, CPP, PET and LLDPE films, as well as paper and nonwoven materials. It can also be configured for applications such as paper bags and PP woven bags.

For applications requiring additional surface treatment, corona treatment can be integrated into the production line to improve ink adhesion on suitable substrates.

Double-Sided Printing for Greater Production Flexibility

For converters producing packaging that requires printing on both sides of the substrate, Changhong’s stack type configuration supports double-sided printing.

The machine can also be equipped with double pneumatic loading and unloading systems, helping improve material changeover efficiency and reduce manual handling during production.

Depending on production requirements, additional functions such as an automatic inspection system can also be considered. These configurations allow converters to build a printing line around their actual production requirements instead of investing in functions that they may not need.

A Practical Choice for Different Production Requirements

The stack type flexo printing machine is positioned as an economical and flexible option for converters that need to handle different substrates and packaging applications.

Compared with equipment designed for only one specific material or product, the stack configuration provides greater flexibility for companies producing a variety of packaging orders. It can be used for short and medium production runs as well as continuous packaging production, depending on the machine configuration and application.

For manufacturers producing plastic bags, paper bags, nonwoven packaging or PP woven bags, the ability to adjust printing configurations according to the substrate and product requirements can help improve equipment utilization.

Built Around Stable Operation and Easy Production

Changhong focuses on practical machine design and reliable operation. The printing units use independent servo motors, while the material feeding and tension systems are designed to keep the web running smoothly throughout the printing process.

The machine’s operating structure is also designed to make routine production adjustments more manageable. This is important for converters handling multiple SKUs and different packaging materials, where frequent job changes require a printing machine that can adapt to different production conditions.

By combining multi-color printing, double-sided printing capability, material flexibility and controlled web handling, Changhong’s stack type flexo printing machine provides a practical platform for flexible packaging manufacturers seeking a versatile flexographic printing solution.

Supporting the Development of Flexible Packaging

As packaging manufacturers continue to work with more material types, product specifications and customized orders, printing equipment needs to provide both stable performance and production flexibility.

Changhong’s stack type flexo printing machine is designed around this requirement, offering configurations for different substrates, printing widths and color requirements. From plastic film and paper to nonwoven and PP woven materials, the machine can be adapted to a variety of packaging applications.

For converters looking for an economical flexographic printing machine with flexible configuration options, the Changhong stack type flexo printing machine provides a practical solution for expanding printing capabilities and supporting diversified packaging production.
