Ideal for the office or for home, BPA-free Avery labels for direct thermal printers are ideal for almost any job. These tough labels can withstand some of the harshest conditions and are resistant to water, scratches, smudges and grease making them ideal for a wide variety of labeling projects. These labels are also compatible with multiple thermal printers including Dymo printers, Seiko printers and Zebra printers. Each thermal label roll is sealed in a secure bag to protect the light-sensitive material from damage. At the center of each roll is a core that is 1" in diameter. For best results, a use-by date is also included to help make sure labels are printed at the highest quality. The matte white label material provides a bright contrast to help print stand out and be readable. Thermal labels don't require toner or ink and are ideal for businesses or offices that need labels on demand.
