The growth of e-commerce has fundamentally reshaped the paper converting industry, introducing new manufacturing standards in terms of speed, sustainability, and process integration. Among the products experiencing the strongest market growth are paper padded mailers, which are increasingly replacing traditional plastic packaging solutions. In this segment, competitiveness depends not only on the quality of the finished product but also on the ability to manufacture it through a continuous, efficient, and scalable production process.
A key factor is inline printing, integrated directly into the paper converting process. Logos, branding, technical information, and functional graphics must be applied without interrupting production.
This raises a critical question for paper converting manufacturers: Which printing technology offers the best balance of productivity, print quality, and continuous operation?
Flexographic printing and industrial inkjet: two different manufacturing approaches
In recent years, industrial inkjet printing has gained market share thanks to its flexibility, particularly in applications involving variable data, extensive customization, or short production runs.
Flexographic printing, by contrast, follows an entirely different manufacturing philosophy based on maximum production continuity, high operating speeds, and an exceptionally competitive cost per linear meter.
The two technologies are therefore not direct alternatives but are designed to meet different industrial requirements.
When the objective is continuous industrial production of paper packaging materials, flexographic printing remains the most efficient technology.
Inline printing in modern paper converting
In the production of e-commerce padded mailers, printing is no longer a standalone operation but an integral part of the converting line. The paper web is unwound, printed, and converted into the finished product within a continuous production flow. Any interruption or slowdown in the printing system immediately impacts the overall productivity of the line.
For this reason, inline printing has become a strategic choice in industrial paper converting, delivering:
- reduced production lead times
- elimination of offline processing
- improved overall equipment efficiency
- direct process control
Why flexographic printing remains the standard for high-volume production?
Flexographic printing continues to be the preferred technology for high-volume paper converting applications because it delivers:
- uninterrupted production during long print runs
- consistent print quality over time
- high production speeds
- optimized operating costs
- stable process performance across multiple shifts
The ink transfer system based on anilox rollers and printing plates ensures stable, repeatable print quality even under intensive production conditions.
Water-based inks: the standard for modern paper converting
Water-based inks have become the established standard throughout the packaging industry.
Their widespread adoption is driven by:
- reduced environmental impact
- improved operational safety
- compatibility with e-commerce packaging
- excellent integration with flexographic printing
The combination of flexographic printing and water-based inks enables a stable, sustainable, and high-performance manufacturing process.
Key requirements for a printing press for padded mailers
Modern paper converting lines require printing systems specifically designed for continuous operation without becoming a production bottleneck.
The essential requirements include:
- high registration accuracy
- consistent ink transfer
- fast setup
- reduced waste
- seamless inline integration
- reliable performance in multi-shift production
Modular™ 928: Giugni®’s inline flexographic printing solution
To meet the requirements of modern paper converting, Giugni® has developed Modular™ 928, a flexographic printing press specifically designed for integration into automated paper converting lines. Its modular architecture enables flexible configurations according to the production line layout and the customer’s manufacturing requirements, providing exceptional adaptability across a wide range of industrial applications.
One of its most significant technical features is a maximum print width of up to 1100 mm, making it suitable for a broad range of paper converting applications, including e-commerce padded mailers and other large-format packaging products while ensuring consistent print quality across the entire web width.
Modular™ 928 incorporates a flexographic printing unit equipped with a closed chamber doctor blade system, ensuring precise and consistent control of the ink film transferred to the anilox roller.
This system provides:
- excellent colour consistency throughout the production run
- reduced ink consumption and evaporation
- improved cleanliness of the printing system
- reduced maintenance requirements
Another distinctive feature is the flexographic sleeve system, which enables automatic repeat length changeover. This solution allows the press to adapt quickly to different print repeats, significantly reducing setup times while increasing the operational flexibility of the production line.
For paper converting manufacturers handling multiple formats or frequent job changes, this translates into higher machine availability and improved production utilization. From an operational perspective, the stability of the printing unit and the precision of the ink delivery system ensure consistent print quality even during long production runs, reducing waste and improving overall process predictability.
Compatibility with water-based inks further enhances Modular™ 928, making it fully aligned with the requirements of sustainable packaging and modern paper converting.
Main technical features of Modular™ 928
- print width up to 1100 mm
- high-precision flexographic printing system
- closed chamber doctor blade system
- flexographic sleeve system
- automatic print repeat changeover
- integration into continuous paper converting lines
- excellent registration stability during long production runs
- reduced setup times and machine downtime
- compatibility with water-based inks
Flexographic printing or industrial inkjet?
The choice between flexographic printing and industrial inkjet should be based on the production model. Industrial inkjet is an effective solution for flexible production and highly customized applications.
Flexographic printing, however, remains the benchmark technology for continuous high-volume manufacturing thanks to its efficiency, process stability, and cost competitiveness.
In this context, Giugni® Modular™ 928, featuring a print width of up to 1100 mm, a closed chamber doctor blade system, and sleeve technology with automatic print repeat changeover, provides a practical and highly efficient solution for the modern paper converting industry producing padded mailers for e-commerce applications.
