Grain Bags
We are the suppliers of Australian Made Grain Bag filling and emptying machines as well as the Easyloader for filling Grain Bags direct from a truck.
Storing your grain in bags during a busy harvest is a great alternative to silo storage and or freight. On-farm storage is also a cost-effective and affordable alternative during harvest, providing growers with the option of being self-sustaining, taking advantage of market changes, as well as having unlimited storage and maximising general harvest efficiency.
Advantages of storing in Grain Bags
- Low cost per tonne of stored grain
- Allows you to segregate different grains and quality for commercial identity
- The capacity of the on-farm storage is remarkably increased which enables you to increase efficiency and capacity of harvesting
- Easy sampling of grains stored
- Avoiding high priced freight, long turn-around times and availability of trucks during harvest
Grain Bag Manufacture
Grain bags are manufactured from polyethylene through a 3-layer co-extrusion process, each layer with different and specific properties. These layers are melted, thus producing a single uniform film. Additives such as titanium dioxide and UV stabilizers are added to the white (external) layer and a high concentration of carbon black is added to the black (internal) layer.
This process provides the following important properties
- Mechanical resistance: e.g. Perforation resistance
- Thermal resistance
- Good stretching
- Internal temperature stability
- Impermeability
- Reflection of solar rays
- Durability
- Flexibility
- Softness
- Internal opacity to block out the sunlight
At Heard’s Hire we offer Harwell Grain Bags, a 3-layer bag available in 60 and 75 metre lengths (90 metres available upon request).
