Why select our UniPak silage wrap?
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, an excellent oxygen barrier, 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.

Unipak Silopower25 - 7 layer Silage Wrap
The new high performance, 7 layer silage film for Australia.The formulation of SiloPower is designed to be used withall types of wrappers.
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.
Benefits of 7 layers
- Total uniformity
- Excellent bale sealing
- Improved dart drop
- Secure UV protection
- High puncture resistance
- High tear resistance
- Smooth outside layer on bale
