The development of sacks and sack paper has a history of the same age as our mills. The original US. Patent 47376 for square bottom paper sacks is slightly older than Nordic Paper Bäckhammar mill and the US. patent 623199 for valve sacks is slightly younger. And all this time we have produced the paper to produce the sacks. 

Bäckhammar pulp and paper mill has produced paper since 1871. It is now focusing on niche grades of unbleached Sack, MF and MG kraft papers, as well as special end use adaptions of these grades. The mill is situated in the south-eastern part of the Swedish province Wermland. As a part of Nordic Paper, the Bäckhammar pulp and paper mill is certified ISO9001, FSC® (FSC-C102767) and PEFC (PEFC/05-33-213).
