<p>A laminate which comprises: a heat-sealable layer obtained by forming a mixture of a synthetic pulp of a branched shape with short synthetic fibers into a sheet; and tenaciously united therewith a base layer formed from natural fibers. The synthetic pulp is one prepared from a resin composition comprising an ethylene / α, β-unsaturated carboxylic acid copolymer and polyethylene. The laminate has high air permeability and combines high heat-seal strength and satisfactory hot tackiness even at a sealing temperature of 130°C. It is hence suitable for use as a heat-seal paper in filter applications, especially as a paper for tea bags.</p> |
