  • Avoid Labeling Mistakes by Removing Plant Air Posted last month
    All-electric label applicators revolutionize the packaging industry by eliminating the reliance on plant air, providing precise applicator control for consistent and accurate label placement and ensuring secure label control for various label sizes.
  • Is training production line workers creating a challenge? No problem!  Posted 6 years ago
    Companies rely on engineers or technicians to keep production lines up and running. These job functions are essential to hitting production targets, so it is key that their skill level on equipment is proficient. When making the decision to replace this equipment, the amount of time and money that will have to be invested in training your labor is a major deciding factor.
  • How do I get labels to stick in hot and humid environments? Posted 3 years ago
    Something to be aware of when considering using labeling for product identification in a hot or humid environment is that labels are sensitive to temperature, making facility environment temperature a determining factor in choosing what label material to use on a product.

Side by Side Comparison: Fiber Lasers and CO2 Lasers

A different laser technology has been getting some new press lately, thanks in part to growth in the Fast-Moving Consumer Goods (FMCG) market. Fiber lasers aren’t new, but their application in the consumer packaged goods market has definitely hit a growth spurt. Product packaging is evolving and making use of different materials, like High Density Polyethylene or HDPE which is most desirable for its high-quality presentation, durability, and versatility in handling liquids from automotive oils to shampoo and specialty drinks.  It’s no mistake then that the fastest growing laser marking technology is fiber laser which has the ability to mark directly onto HDPE as well as a range of materials not previously well served with CO2 lasers.

What then, are the other key differences between CO2 and fiber lasers?:

  • Fiber lasers don’t necessarily use more power, but do use power differently.  The laser beam produced is in a different part of the light spectrum and is a much tighter beam.  This is what allows the laser to mark materials that other lasers can’t, such as HDPE.  Or, mark into other materials better such as rubber and metals.

  • By comparison, fiber laser can be quite small and compact.  Instead of a bulky tube of gas, fiber lasers use optical fiber as their lasing medium.  The exact science of it can be quite detailed but the bottom line is: these lasers are compact and have a small footprint.  This allows for easy and convenient installation to the packaging line.

  • Like most industrial equipment, fiber lasers do come with their own set of safety requirements which can be managed safely through proper guarding and training.
