摘要：
An improved chemical protective garment is provided by first forming a multilayer film structure (10) having an inner layer of substantially isotactic oriented polypropylene homopolymer (14) sandwiched between a layer of ethylene-propylene random copolymer (12) and a layer of ethylene-vinyl acetate (16). The multilayer film structure is then bonded to a two-layer polyester substrate (22, 24) using an elastomeric adhesive (18). 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.
