摘要: A heat seal infusion packing material for such articles as tea bags and the like includes multicomponent thermoplastic fibers as a significant portion of the heat seal fibers. The multicomponent heat seal fibers provide improved seal strength and infusion characteristics over a broad operational window while reducing the heat seal fiber concentration within the sheet material.
