ABSTRACT:
A heat sealable, adhesive-free seam and closure fabrics and clothing comprising the combination of a fabric scrim and a heat sealable water and vapor resistant coextruded laminations which provides a barrier against liquid substances and vapors. The coextrusion laminations are in abutment or overlap and comprise a film layer with an outer and inner layer of low density polyethylene and an intermediate layer of a copolymer of ethylene and vinyl alcohol. The laminations are fusion bonded to a portion of the scrim in a manner whereby the polyethylene flows from said lamination, encapsulates the ends of the intermediate layer of the laminate and forms weld points with the said scrim to prevent penetration by liquid substances and vapors.
