This bale wrap film is a five-layer, UV-stabilized polyethylene sheet used to seal round bales of silage or haylage. It is applied by the rotating table and film carriage of a wrapper, where tension stretches the film around the bale to create an airtight seal. The white color reflects solar radiation, reducing internal bale temperature during the outdoor storage period. The film's thickness and layer count contribute to its resistance against punctures from stubble or handling equipment. A tear or pinhole in the wrap allows oxygen ingress, which can trigger aerobic spoilage and reduce feed quality. On installation, ensure the film roll is centered on the carriage spindle and that the pre-stretch rollers are adjusted to the manufacturer’s tension specification.
