Abstract

A flexible, high chemical barrier film with modified surface characteristics is used to form an effective contamination infiltration barrier that offers a significant and drastic improvement as compared to the polyethylene-based sheeting materials presently used for this purpose. The flexible multi-layered barrier film has two opposing surfaces, at least one of which has a surface energy of 35 dynes/cm or greater. The barrier film also has a permeation efficiency greater than 50% when exposed to the chemicals included on ASTM 1001 and offers resistance to military chemical agents, toxic industrial chemicals, and biological hazards.
