A viral barrier composite of a thermoplastic film (24) thermally bonded on at least one side thereof to a breathable thermoplastic web (22), and method for making the same. The viral barrier composite has viral barrier properties, a moisture vapor transmission rate of at least 700 g/m2/24 hours and a bond strength between the thermoplastic film breathable thermoplastic web of at least 0.07 N/cm. The viral barrier composite is formed by calendering an assembly comprising a thermoplastic film (24) and a breathable thermoplastic web (22) between a smooth roll (28) and a pattern roll (26). The viral barrier composite may be used for constructing articles of protective apparel. |
