Silage is a fermented fodder which is having high moisture and can be fed to sheep, cattle, and various other animals. It can be made from many field crops. It can be produced by placing green vegetation in a silo or a pit, compressed as much as possible leaving little oxygen access, and covered by a thin polymeric sheet or a film. The polymeric sheet which is used to cover the vegetation is referred to as silage film. The silage film became an integral part of animal nutrition, as it facilitated the formation of perfect silage. It is essential to employ best quality silage films for the proper transformation of grass and other green vegetation into silage.
