Choosing the Right Technique

The choice of printing method depends on:

  • Budget: Cost-effective methods like flexographic printing work for basic designs, while premium finishes like foil stamping add luxury at a higher cost.
  • Paper Type: Coated papers work well with offset or digital printing, while textured papers pair better with screen or letterpress printing.

By combining the right technique with thoughtful design, manufacturers can produce customized paper bags that meet both functional and aesthetic goals.
