ABSTRACT:
Olefin polymer films are produced comprising amounts of one or more permeability reducing fatty acid derivative compounds. The resultant films have improved barrier abilities as evidenced by reduced methyl bromide diffusion rates. The films are very suitably employed as soil fumigation tarpaulins or soil covering materials. Improved methods for confining chemical treatment agents are also taught.
