Pannier introduced the bar code metal tag in the 1980s as an alternative to less durable paper and plastic labels. Our specially coated laser printable tags are made to withstand extreme industrial processes in the metals, automotive, oil & gas industries.
Bar Coding in the Harshest Environments
Metal tags perform reliably in the most harsh manufacturing environments. Metal tags:
- can be applied to red-hot products in excess of 1800°F
- withstand immersion in acids, oils, water, and other fluids
- are rigid and can be securely attached to products with uneven surfaces or products that have oil or moisture on the surface
- will not tear, deteriorate, or fall off during handling, processing, or shipping
- withstand prolonged exposure to weather conditions such as heat, salt, humidity, and UV rays
On-demand Printing
Tags can be ordered pre-printed or blank for use with Pannier Metal Tag Printers. Information such as text, graphics, bar codes, and 2D codes can be printed in seconds. Tags are supplied in coiled form, nicked and notched for easy separation after printing.
