Table 3 Properties of paper sheets from Phaeophyceae obtained by different treatments (P: hydrogen peroxide; P-HCl: hydrogen peroxide and hydrochloric acid; P-PBS: hydrogen peroxide and sodium perborate; HW: hot water, blank). Paper sheets are formed mixing pulps of Phaeophyceae and Pine pinaster at different proportions (75:25 and 25:75). Y: Yield, TI: Tear index, ST: Stretch, BR: Burst index, BL: Breaking length and Brightness (%) (%) Prop.
