So, if you want a premium quality silage film product without a ridiculously high price tag then we’d like to invite you to try our range and see the difference in quality and price for yourself.
All of our silage stretch film products are manufactured from high quality resins and raw materials. We also ensure the highest quality UV additives and colourants are used, providing a silage film range that boasts excellent performance along with a very high level of UV protection. This translates to bale wrapping products that provide year round protection in the harshest of Australian conditions.
Whether you are wrapping round bales or square bales, Unipak silage wrap products maintain excellent tear resistance, puncture resistance and breaking strength. So you can get on with the baling and wrapping tasks at hand, with less stoppages.
Good levels of tack in our films mean that Unipak silage wrap products provide an air tight seal, so your wrapped bales will be well protected from oxygen ingress.

SiloPower sets a new standard for high quality agriculture stretch films. The 7 layer technology further improves film behaviour. Aside from higher dart drop and tear strength, 7 layer film shows a significant decrease of thickness tolerances. For example, standard 3 layer films shows ± 12% and 5 layer films ± 8%. The 7 layer technology reduces the tolerance to as little as ± 3%, on average.
The low production tolerances on the 7 layer film lead to a near-perfect uniformity in film quality, preventing weak areas where the film could break. The quality of the silage significantly depends on the bale being airtight. SiloPower – wrapped silage shows excellent results when using at least 6 rounds of wrapping around the pack with an overlap of film of 50% between the layers.
