RaniWrap is a co-extruded, multi-layer, bale wrap stretch film that is fully UV-stabilized. Producer Rani Plast was one of the first agricultural film manufacturers to research and develop green silage films to optimize sun reflectivity, keeping bales as much as 30-35 degrees cooler in warm temperatures compared to traditional black bale wraps. Cooler bales minimize secondary stretching of the bale wrap film and reduce condensation of moisture in the bale. The specialized UV stabilizer in RaniWrap is present in every layer, providing effective protection against harmful UV radiation and the resulting feed degradation.
Bale Wrapping Best Practices for Optimal Feed Quality
The quality and feeding value of a silage bale depends considerably on prompt and proper application of a high performing bale wrap film.
Wrap your bales where you will store them. Excessive handling of wrapped bales increases the risk of damaged bale wrap leading to feed spoilage. If you do damage the bale wrap, promptly repair it with silage film repair tape.
Clean, dense, uniform bales produce the highest quality baleage. Even the best performing bale wrap can’t make up for poorly baled forage. Wrap compact, well-shaped bales promptly (within two hours if possible) and wrap them tightly to minimize trapped air for optimal fermentation.
Pre-stretch the wrap according to manufacturer instructions, typically 55-70%. Lighter bale wrap films allow for visual inspection of the layers to ensure complete coverage.
Apply at least 6 layers of bale wrap film, with 50% overlap between layers. Research has shown that 4 layers of wrap resulted in up to 9% bale spoilage, while 6 layers had virtually no forage loss. In hotter climates, 8-12 layers of bale wrap may be needed to adequately protect individual bales or the area where bales in line abut.
Store Wrapped Bales with Care
Stack wrapped bales on their ends, not more than two high if possible, in a level, dry location without vegetation to draw birds or other animals. Handle wrapped bales as little as possible. If a wrapped bale is damaged, repair the film immediately with a high-quality silage film repair tape. Note that some agrochemicals, such as pesticides with sulphur or chlorine can damage silage plastic.
Protect rolls of bale wrap film from damage by storing them upright in a cool, dry area. Inspect rolls of film for damage before using them. Spare film can be used the next season if it is stored properly and is undamaged.
