Sizing Guidelines

Material Recommendations

  • • Indoor: Standard paper labels work fine
  • • Outdoor: Use synthetic (polypropylene) labels
  • • High-wear: Laminate or use polyester labels
  • • Cold storage: Use freezer-grade adhesive

Printing

  • • Laser printers produce sharper codes than inkjet
  • • Thermal printers are ideal for high-volume labeling
  • • Always test scan before bulk printing
