Abstract
The present technology generally relates to multilayer films having breathable regions which are suitable for use as broadcast fumigation films and for other applications. More particularly, the present technology relates to multilayer films comprising at least one breathable layer and at least one barrier layer, where the layers are arranged so that the multilayer film has at least one region, such as at the edge of the film, that is breathable throughout its thickness. The present technology also relates to methods of manufacturing and using such multilayer films.
