Abstract
Composite chemical barrier films and fabrics that are particularly useful in protective garments. The composite barrier material may be made by laminating a barrier film to a flexible substrate using a thermoplastic resin and topcoating the barrier film with a similar or dissimilar thermoplastic resin to allow fabric seaming when the fabric is fabricated into a protective garment. Protective garments made from the materials are lightweight while maintaining an adequate balance of strength and chemical protection.
