Abstract
An improved chemical protective garment is provided by first forming a multilayer film structure having an inner layer of substantially isotactic oriented polypropylene homopolymer sandwiched between a layer of ethylene-propylene random copolymer and a layer of ethylene-vinyl acetate. The multilayer film structure is then bonded to a two-layer polyester substrate using an elastomeric adhesive. In a preferred embodiment, a barrier material having a layer of ethylene-vinyl alcohol is combined with the multilayer film structure to form a composite, which is then combined with the substrate.
