3W vs 5W vs 10W diode laser for kraft paper engraving
I’m starting a small packaging business and planning to engrave kraft paper belly bands (the wrap around boxes with text + QR code).
Material is thin kraft paper (not thick cardboard), and I’m aiming for clean, light engraving so no cutting or deep burns.
I’m deciding between 3W, 5W, and 10W diode lasers (not going CO2), and budget is definitely a factor.
Main concerns:
Avoiding burn marks / charring
Clean text and sharp QR codes
Reasonable speed for small batch production
Overall value for money
I know even low watt lasers can engrave paper, but I’m worried lower power might mean slower speeds → more heat → worse results.
Would 3W or 5W be enough, or is 10W worth the extra cost for cleaner results and efficiency?
Would really appreciate any real-world experience, especially if you’ve worked with kraft paper specifically. Thanks 🙏
