Flexographic printing machinePackaging Bag Printing Methods Explained: Flexo, Gravure, and Digital PrintingFlexographic printing machine

High-quality printing is essential for modern packaging, especially for BOPP woven bags, kraft paper bags, industrial PE/PP bags, and multi-layer soft packaging films. At Zhixin Packaging, we use professional printing technologies to ensure your packaging is clean, vibrant, and aligned with your brand identity.

Below is a complete guide to the three major printing methods used in the packaging industry.


1. Flexographic Printing (Flexo Printing)

Best for woven bags, kraft paper bags, and cost-efficient industrial packaging.

Flexographic printing uses a flexible photopolymer plate and an anilox roller to transfer ink onto the substrate. It is one of the most commonly used printing methods for PP woven bags and kraft paper bags.

Key Advantages

  • Fast plate-making: 1–2 days

  • Lower cost compared with gravure printing

  • Suitable for high-speed, large-volume production

  • Works on PP woven fabric, kraft paper, PE/PP films

  • Supports eco-friendly water-based inks

When Flexo Is Recommended

  • Standard PP woven bags

  • BOPP laminated woven bags (simple designs)

  • Kraft paper bags / multi-wall valve bags

  • Agricultural & industrial packaging (feed, fertilizer, seeds, grain)


2. Gravure Printing (Rotogravure Printing)

Best for high-resolution, full-color, premium packaging.

Gravure printing uses engraved cylinders that hold ink in recessed cells, providing extremely fine detail and vivid color reproduction. It is the preferred method for premium BOPP laminated bags and soft packaging films.

Key Advantages

  • Top-level print quality (photo-quality images and gradients)

  • Fast cylinder-making: 3–5 days

  • Excellent color saturation

  • Strong ink adhesion and scratch resistance

  • Ideal for PET/NY/CPP/PE laminated structures

When Gravure Is Recommended

  • High-end BOPP laminated woven bags

  • Soft packaging for food, chemicals, or industrial use

  • Designs requiring fine details and rich colors

  • Products needing premium appearance and long-term durability


3. Digital Printing (For Small Runs & Prototyping)

Digital printing is ideal for samples, marketing tests, and low-volume customization.

Key Advantages

  • No plate-making required

  • Perfect for pre-production samples

  • Short turnaround time

  • Good color performance

Limitations

  • Higher cost per piece

  • Not suitable for mass production

  • Limited printing effect on woven fabric

When Digital Printing Helps

  • Client presentations

  • Design confirmation before production

  • Small batch specialty packaging
