Grünperga’s Super Klar Glassine paper accesses NF 316

Our principals Grünperga are specialists of glassine papers which are used for the windows of envelopes. Since April 2012 their quality Super Klar in 35 gsm is available for envelope manufacturers making use of the Afnor NF 316 standard. This recent rule aims at reducing the negative impacts of envelope production on the environment.

Thanks to its involvement in this matter Grünperga has demonstrated the compatibility of Super Klar 35 gsm with the requirements of the NF 316 standard.
Super Klar in 32 gsm will also be eligible for NF 316 when the changes in technical specifications of the paper are officially published by AFNOR.

Thanks to optimal readability performance on automatic devices and good mechanical properties Grünperga is approved supplier of the German post for many years. The mill now supplies its paper to the French market under the NF 316 standard, which is a guarantee of quality for manufacturers of envelopes.
