Abstract
A mulch barrier film having, for example, a methyl bromide permeability of less than about 15 g/m-hr and machine direction Elmendorf tear strength of at least about 75 gf. The mulch barrier film is an extruded, cast, and preferably embossed, multilayer film having at least one polyolefin layer and at least one polyamide layer. The combination of the film structure and the casting process achieves a barrier film that has low permeability to volatile soil treatment chemicals, such as methyl bromide, and superior tear strength properties.
