Warehouses use a special kind of highly durable bar code labels to maintain a list of their inventories. The basic types of warehouse bar code labels are reflective, location, floor and pallet.

Reflective bar code labels are large in size, about 8” by 16,” and they contain both bar codes and a number that can be read by human eyes. They are durable and can be scanned from distances as much as 30 feet. These labels can be printed or blank and are able to be used both indoors and outdoors. In order to provide more durability, they can be laminated.

Location labels are used for pinpointing the position of items. They are stuck on racks or shelves where inventories are placed. These labels have alphanumeric codes, by which they are registered. Since location labels are mostly stuck on metal surfaces, they need to have strong adhesives. Once adhered, they cannot be peeled off. Location labels may be matte finish or polished. They are mostly made of metals.

Floor bar code labels are also large in size and they are stuck on the floor with special adhesives. They are used if there is no other place for the bar code to be stuck. Floor labels require high quality materials because they have to endurance heavy pressure all the time. They are made of

If the inventories are on the move, then pallet labels work best for them. These labels are made very tough to withstand severe conditions. Their bodies are made of hardened plastic or metal and have special adhesives.

Reflection, location and floor bar code labels are generally available in preprinted conditions. They have bar codes along with alphanumerical codes in a sequential order. The warehouse owners themselves can design pallet labels using printing equipment. Warehouses use thermal or thermal transfer printers to print their own bar code labels to obtain greater accuracy and clarity.
