GREENFINISH is the innovative release paper finishing line with very low environmental impact. It is the first system to use the GREENSTARs roller coating machine to coat the thermo-adhesive on both corrected grain and full grain leathers.
The standard line is complete with accumulator and allows non-stop processing 24/24, ideal for tanneries that have large production batches.
The unwinder, the rewinder and the cleaning machine unit are designed in separate modules to eliminate any type of interruption or downtime: on request, it is possible to increase the working speed, lengthening the infrared tunnels and adding a second head for the finishing of coarse grains.

The line combines efficiency and eco-sustainability aspects:
- combine efficient and ecological performance;
- it creates a covering effect that evenly covers the surface of the leather, even on the most defective examples;
- minimisation of negative environmental impacts with the reduction of energy waste and the elimination of atmospheric emissions.


Among the main innovations made by this finishing system are:
- the possibility of finishing any type of leathers, even those buffed or with defects, with a single step with considerable benefits in reducing costs and working times
- the possibility of obtaining an almost completely finished leather that can be customized with replacements and fixatives
- compared to spray and roller finishing, the reduction of finishing steps which, consequently, reduces the risk of contamination to a minimum
- the possibility of reusing the release paper, now consumed after 30 passes, also in an alternative way, i.e. as a matrix for products with smooth base (drummed or with larger prints).
