The ability of a film to withstand impact, vermin and extremes of climate is the main consideration with those selecting films. Price is often a secondary consideration with few opting for cheap unbranded makes over a recognised name. However, whatever the make of film, damage from birds and vermin, handling and storage remains an issue. It is the opinion of many farmers, contractors and agricultural experts that a new generation of films needs to be developed that will resist puncture and even self-seal if damaged. But despite cost being a lesser issue, farmers and contractors are unwilling to pay for more layers of wrap in an effort to minimise these damaging influences. Farmers can sometimes lose up to 50% of bales through punctures. “Birds landing on the bales while they are standing in the field fresh from wrapping are the biggest problem. Maybe it is the heat coming from the silage as it ferments, or maybe the bale simply acts as a vantage point, but it prevents farmers from leaving bales in the field more than a few hours”, commented a UK contractor. |
