Stahl Upgrading Solutions

With only perfectly smooth leather being good enough in apparel, accessories and home interior industries, tanners and manufacturers face increased demand for high-end, premium leather. But there’s a limit to the available raw material. The good news is that Stahl’s portfolio of leather upgrading solutions can help turn average leather into excellent leather.

Upgrading leather quality
Applying our easy-to-use techniques to the leather substrate can mask almost any type of grain defect. This increases the quality of the leather and the usable surface area. The result is a higher yield of smooth, fashionable leather with a natural feel and classic elegance. That means it doesn’t just improve the product, but also the amount of material.

This upgrading can be done at several phases in the production process, depending on the solution you choose.
