CO2 Laser Marking Machines

Fast, ink-free date and lot coding on cartons, labels, PET, glass and wood.

Also called CO2 laser coders, scribing lasers and carton laser markers.

CO2 Laser Marking Machines
Overview

What these machines do

CO2 lasers produce far-infrared light between 9.3 and 10.6 µm, which organic materials absorb strongly. They remove a thin layer of ink from a carton, engrave PET and glass, or change the colour of coated paper — at line speeds that match beverage and FMCG production.

An RF-excited sealed tube generates the beam, and a galvo scan head writes characters as continuous vector strokes. Choosing the wavelength matters: 10.6 µm suits paper, board, glass and wood; 9.3 µm gives a clean frosted mark on PET bottles; 10.2 µm works well on laminated cartons and coated films.

Typical options

  • Choice of 9.3, 10.2 or 10.6 µm tube
  • IP65 washdown head for wet filling halls
  • Beam delivery extensions and 90° turning units
  • Dual-head controller for two lanes

How it works

Process sequence

Trigger

A sensor detects each pack; the encoder supplies line speed.

Compose

The controller builds the message from real-time date, shift and counter data.

Scribe

The scan head writes the code while the product keeps moving.

Extract

A fume extractor captures ablated ink and dust.

Confirm

A code reader or OCR camera checks presence and legibility.

FAQ

Common questions

Which wavelength should I use on PET bottles?
9.3 µm is the standard choice. It creates a shallow, frosted mark with good contrast and far less risk of thinning the bottle wall than 10.6 µm.
Can CO2 lasers mark bare metal?
Not effectively. Bare metals reflect CO2 wavelengths; use a fiber laser. CO2 does work on painted or anodised metal by removing the coating.
How long does a CO2 tube last?
Sealed RF tubes typically run for tens of thousands of hours before a regas is needed. Service interval depends on duty cycle and cooling.
