The inner forage film, also known as the inner layer of silage wrap, is a crucial component in the silage preservation process, especially when used in conjunction with an outer layer. It serves as the first line of defense, directly contacting the forage, forming a tight seal around the bale to create an anaerobic environment. This environment is essential for the fermentation process that preserves the nutritional value of the forage, ensuring it remains fresh and suitable for livestock consumption over extended periods.
