Södra gold birch Z

Pulp

A northern bleached hardwood kraft pulp made from birch. Södra gold birch Z has the highest tensile strength of any product in Södra’s portfolio. Switch from eucalyptus and you’ll notice the difference immediately when it comes to tensile strength, without compromising on softness. This is a great choice if you want the softness of hardwood with the tensile strength of softwood. And it has the added advantage of carrying both the TCF and PEFC or FSC® guarantees.

Södra Gold

Softness and strength, close to the source

The raw material in Södra gold is hardwood, which has shorter fibres than softwood. The advantage of these short birch fibres is that they combine good formation properties with excellent tensile and Z-strength. These fibres will also create a very soft sheet if required.
