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.
