Leather labels are widely used on garments, bags, shoes, and other products. The main difference between real leather labels and PU labels is the material they are made of.

Real leather labels are made from animal hides, typically from cows, goats, or sheep. The leather can be processed in various ways to create different textures, finishes, and colors. Leather labels are known for their durability, natural look and feel, and ability to age well over time. They are often used on high-end products that require a premium look and feel.

On the other hand, PU (polyurethane) labels are synthetic labels made from a plastic-based material. PU labels can be made to look and feel like real leather, but they are not as durable or long-lasting. They are less expensive than real leather labels and are often used on products that are priced more affordably.

In summary, the main differences between real leather labels and PU labels are the materials they are made of, their durability, and their price. Real leather labels are more durable and premium in look and feel, while PU labels are less expensive and often used on more affordable products.

It should be noted that one should not unilaterally say which leather is better. They both have their own advantages and disadvantages, so you should choose according to your own needs.
