What makes them unique?
The grain bag is a laminated mix of three layers of polyethylene with the first two layers acting as a UV filter. The third layer is black and is designed to keep out the sunlight.
The bags are designed to stretch to a maximum of 10% measured during the filling process to prevent overfilling.
The unique, specialized-design of grain bags allow for storage versatility, whether in the field where harvesting is taking place or a grain storage site, as long as the bags are placed on clean ground with good drainage and free of sharp objects.
