HOT-EXTRACTION PAPER

In the case of a hot-extraction paper consisting substantially of cellulose and manufacturing assistants needed in cellulose production， such as pH modifiers based on acids and/or bases， the paper comprises exclusively cellulose having fibre lengths of at least 2.0 mm on length-weighted average， more particularly at least 2.5 mm on length-weighted average， and has isotropic extension properties which are substantially equal in machine and cross directions and amount to at least 7.5%， more particularly at least 8.5%.
