摘要：
A viral barrier composite of a thermoplastic film thermally bonded on at least one side thereof to a breathable thermoplastic web, and method for making the same. The viral barrier composite has viral barrier properties, a moisture vapor transmission rate of at least 700 g/m.sup.2 /24 hours and a bond strength between the thermoplastic film and breathable thermoplastic web of at least 0.07N/cm. The viral barrier composite is formed by calendering an assembly comprising a thermoplastic film and a breathable thermoplastic web between a smooth roll and a pattern roll. The viral barrier composite may be used for constructing articles of protective apparel.
