SMS nonwoven is triple protection in one material – two layers of durable spunbond and a middle layer of filtrating meltblown create a barrier that lets air through but stops bacteria and contaminants. This makes SMS perfect for masks, surgical gowns or coveralls, and beyond the medical field, you’ll even find it in vacuum cleaner bags. Spunbond is strong polypropylene nonwoven, meltblown is the master of filtration – together they ensure safety and comfort.
