Abstract (en)
A fibrous, non-woven, non-heat sealable, porous web material comprising natural fibers and 0.5 to 25 percent synthetic material is provided. The web material has properties well suited for use in infusion packages. The web material exhibits improved stiffness and memory characteristics which lead to significantly improved strength of mechanically formed and crimped seams.
