Heat-sealable paper, rolls, packaging bags and packaging materials

Abstract

To provide heat-sealable paper that reduces environmental impact, is easy to open, and is resistant to tearing during opening, as well as rolls, packaging bags, and packaging bodies made using the heat-sealable paper. [Solution] A heat-sealable paper having a heat-seal layer on one side of a paper substrate, wherein the paper substrate content in the heat-sealable paper is 50% by mass or more, and the geometric mean of the pure bending stiffness in the longitudinal direction and the pure bending stiffness in the transverse direction of the heat-sealable paper is 0.80 g·cm 2 A heat-sealable paper having a length of 1.8 kN / m or less, a longitudinal tensile strength of 1.8 kN / m or more, and a static friction coefficient of 0.750 or less on the side of the heat-sealable layer opposite to the paper substrate.
