Synthetic labels are durable, made from materials like polypropylene or polyester, resistant to water, oil, and chemicals. Waterproof stickers are specially designed to withstand moisture and environmental exposure, ensuring longevity. Direct thermal labels utilize heat-sensitive paper, perfect for short-term applications like shipping labels, requiring no ribbon. Thermal transfer labels, on the other hand, use heat to transfer ink from a ribbon onto the label, ideal for long-lasting applications like product labeling or asset management, ensuring clarity and durability.
