Three trials were conducted on commercial farms with the aim of reducing the amount of plastic consumed without reducing the conservation quality of baled silage by using new oxygen high barrier (HB) film instead of commercial polyethylene (PE) film. Bales of lucerne (DM concentration from 400 to 700 g kg-1) were individually wrapped with six layers of conventional PE stretch film or 4 layers of PE - EVOH (Soarnol®) coextruded high oxygen barrier film. The bales were stored outdoors for 330 d. Data confirmed that four layers of high oxygen barrier film could improve hygienic quality of baled silage compared to six layers of commercial PE film, by greatly reducing mould development in two out of three trials at farm conditions.

Abstract
Three trials were conducted on commercial farms with the aim of reducing the amount of plastic consumed without reducing the conservation quality of baled silage by using new oxygen high barrier (HB) film instead of commercial polyethylene (PE) film. Bales of lucerne (DM concentration from 400 to 700 g kg-1) were individually wrapped with six layers of conventional PE stretch film or 4 layers of PE - EVOH (Soarnol®) coextruded high oxygen barrier film. The bales were stored outdoors for 330 d. Data confirmed that four layers of high oxygen barrier film could improve hygienic quality of baled silage compared to six layers of commercial PE film, by greatly reducing mould development in two out of three trials at farm conditions.
