CO2 Flying Laser Marking Machine for Film Packaging Industry | High-Speed Date Coding Solution

1. Why the Film Industry Needs CO2 Flying laser marking machines

Film packaging is one of the most widely used materials in modern industries, especially in food, pharmaceutical, cosmetics, and logistics packaging.

Traditional coding methods such as inkjet printing have several limitations:

• ❌ Requires consumables (ink, solvent)
• ❌ Easy to smudge or fade
• ❌ Risk of contamination for food packaging
• ❌ Higher long-term maintenance cost

👉 CO2 flying laser marking technology provides a better solution:

• ✔ No consumables
• ✔ Permanent and clear marking
• ✔ High-speed inline production capability
• ✔ Eco-friendly and pollution-free
