A protective covering applied to cylindrical hay bales, this material is crucial for preserving forage quality. Constructed primarily from polyethylene, it forms an airtight barrier around the bale, preventing spoilage from moisture and air exposure. This enclosure method allows for the storage of hay outdoors without significant nutrient loss.
Its implementation has revolutionized hay storage practices, reducing reliance on enclosed structures and minimizing waste. The airtight seal inhibits mold and bacterial growth, leading to improved feed value for livestock. Historically, uncovered hay was susceptible to weather damage, resulting in significant losses for agricultural producers. The introduction of this protective measure has significantly enhanced the economic viability of hay production.
