FIELD: paper.
SUBSTANCE: invention relates to a paper-based product. Wet-formed product based on paper contains at least 10 wt. % cellulose fibres with linear density of more than 17 mg/100 m, from 1.0 to 10 wt. % of synthetic non-cellulose fibres and less than 10 wt. % of cellulose fibres with linear density of less than 17 mg/100 m and average fibre length of more than 1.2 m. Synthetic fibres are selected from a group consisting of polyesters, polyalkylenes, polyacrylonitriles and polyamides. Product is characterized by a TS7 value of less than 11 and a geometrical average tensile strength of 500 to 1200 g/3 inches.
EFFECT: higher strength of the product based on paper.
