<p>New process for preparing a fiber sheet by using paper techniques, with a pH comprised between 6.2 and 9.5, from fibers, an organic polymer binder, an organic cationic flocculant and an agent reducing the adherence of the sheet to the wet presses during the formation of the sheet. The sheet obtained according to said method, of which the pH of the aqueous extract is higher than 7, and which exhibits improved mechanical properties particularly as to the tensile strength, the bursting resistance, the impact resistance, the rupture energy and the machinability, is useful in the packaging field and particularly for paper bags.</p> |
