Abstract: A film that provides a fumigant barrier on a raised crop bed includes a barrier material for restricting the flow of a fluid fumigant, and an elastic polymer material for providing elasticity in the film so that the film can be stretched around the crop bed. The barrier material can be a combination of a polyamide, such as copolyamide 6/66, and an amorphous nylon resin. The elastic polymer can be a plastomer, such as an ethylene based octene plastomer or a polyolefin plastomer. The film can also include a polyethylene resin, such as a linear low density polyethylene, to provide strength to the film. The film can be made utilizing a blown film extrusion process.
