I. The Evolution of Multiwall Paper Bags Printing Technologies
The distinction between Multiwall Paper Bags Printing methods represents a critical decision point for procurement professionals managing supply chain risks. As a packaging engineer with 18 years of experience in industrial materials, I’ve witnessed countless instances where improper printing selection resulted in regulatory penalties, brand reputation damage, and product recalls. This section demystifies the technical differences while providing actionable selection criteria.
The “What” of Printing Technologies
Flexographic Printing dominates 78% of the Multiwall Paper Valve Bags market due to its cost efficiency and versatility. Modern flexo presses achieve 300 lpi resolution, enabling microtext and variable data printing critical for pharmaceutical and chemical industries. VidePak’s 12-color Windmöller & Hölscher (W&H) flexo lines deliver:
- Registration Accuracy: ±0.1mm across 1,200mm web widths

- Ink Consumption: 22% reduction through anilox roller optimization
Offset Lithography captures 18% market share for SOM multiwall paper bags targeting consumer markets. VidePak’s Heidelberg Speedmaster CX 102 overcomes kraft paper’s absorbent nature through:
- Plate Technology: Laser-engraved ceramic plates with 50μm cells
- Ink Formulation: Hybrid UV/oxidative inks for 48-hour open time
- Coating Systems: Aqueous varnishes with 3H pencil hardness
Rotogravure commands 4% premium segment for Industrial kraft paper bags requiring 12+ month outdoor durability. VidePak’s Cerutti R983 presses feature:
- Engraving Depths: 65-75μm for 100% ink transfer
- Doctor Blades: Tungsten carbide with 0.1mm wear tolerance
- Web Handling: 600m/min speeds at 10kN tension
The “Why” of Technological Superiority
