What Is Agricultural Bale Wrap Film?
Agricultural bale wrap film—also called silage wrap film, hay bale film, or agricultural stretch film— is a high-performance polyethylene film used to wrap silage, grass, alfalfa, corn stalks, and hay bales. The primary function of bale wrap is to:
- Create an airtight environment for anaerobic fermentation
- Prevent moisture infiltration and spoilage
- Protect forage from UV, rain, and mechanical damage
- Extend storage time and preserve nutritional value
DERFLEX bale wrap film is engineered to meet the needs of modern mechanized agriculture, supporting both round bale wrapping machines and square bale wrapping equipment.
