A general rule is that the more layers and the better the film quality, the smaller is the risk of air entering the bale and allowing moulds to develop. Dow and its partners are engaged in educating farmers and contractors on the benefits of increased film layers and use of top quality films and that trying to save costs by using fewer layers and cheaper films can undermine silage quality and jeopardize the efforts of a whole season. This is definitely a market where the use of poor quality materials is a false economy. Read article

Effectively the converter melts the resin and cools it in the form of a thin layer. This is done in closely specified conditions to provide a film with optimum and consistent properties. Read article
