Abstract
The present invention relates to a laminate prepared in part from a continuous acid polysaccharide film. In various embodiments, the laminate is useful for fabrication as a protective article as it typically is largely impermeable to hazardous chemical and biological agents, but is sufficiently permeable to water vapor that, if worn as protective apparel, it is both protective and comfortable to wear.
