100 mm × 150 mm thermal rolls are medium-to-large-sized label rolls commonly used for shipping labels, invoices, barcodes, and logistics applications. They are available in both direct-thermal and thermal-transfer types. Direct-thermal rolls are heat-sensitive and print without ribbons, offering a convenient and cost-effective solution for short-term labeling, though they are less durable against moisture, oil, heat, and abrasion. Thermal-transfer rolls, which use a ribbon to transfer ink onto the label, produce more durable, smudge- and oil-resistant prints suitable for long-term use in warehousing, logistics, and industrial environments. With their larger size, 100 × 150 mm rolls provide ample space for detailed information, making them ideal for businesses that require clear, legible, and reliable labels for shipping, inventory, or product identification.
