Abstract RU 2782768 C1

FIELD: beverage making.

SUBSTANCE: invention relates to paper for hot extraction, which is used, in particular, as a filter for coffee or tea. Paper for hot extraction essentially consists of cellulose and pH-regulating agents based on acids and/or bases. Paper contains exclusively cellulose with a fiber length of at least 2.0 mm, defined as a weighted length. Paper has isotropic extensibility, which is essentially the same in machine and transverse directions and is at least 7.5%.

EFFECT: increase in tensile strength of paper and pressure resistance, as well as stability of size, and durability at elevated temperatures.
