With the addition of Ecovio® F Mulch, BASF is expanding its line of biodegradable plastic compounds in the form of a grade for use in the manufacture of agricultural films. In contrast to agricultural film made from conventional polyethylene (PE), film made from Ecovio F Mulch biodegrades. It is no longer necessary for farmers to retrieve the film from the field for disposal or recycling after the harvest; they can simply plow it under along with what remains from the plants. To test the performance of its resin, BASF conducted comparative investigations with recognized agricultural institutes in Spain and France. These involved growing vegetables in different locations without mulch film, with conventional PE film as well as with Ecovio F Mulch film. The institutes investigated growth and yield in addition to the tear strength of the film.
