Abstract
Heat-sealable paper including one or more heat-sealable layers on at least one surface of a paper substrate, wherein the heat-sealable layer contains a water-dispersible resin binder, a longitudinal and transverse geometric mean of a tear index of the heat-sealable paper is 10 mN·m2/g or more, a burst index of the heat-sealable paper is 3.0 kPa·m2/g or more, and when two such heat-sealable layers are heat-sealed to each other at 150° C. and 0.2 MPa for one second, a heat sealing peel strength is 2.0 N/15 mm or more and 10 N/15 mm or less.
