Which is the toughest silage film?

Silage film has to cope with some pretty rough treatment. While its main purpose is to provide optimum fermentation by keeping the air, light and water out, first it has to survive wrapping, handling and stacking.

That’s why when evaluating products to replace our earlier generations of silage films we put toughness, tackiness and UV resistance at the top of the check list and PowerStretch was the easy winner.

When it comes to its tear resistance (transverse direction) PowerStretch is more than twice as tough as the Swedish National Testing Institute minimum standard.  And its capacity to withstand dynamic impact force - that is, its puncture resistance - is 70% higher than standard films as illustrated in the chart below.

Breaking strength is higher too, in fact 35% higher than standard films and tackiness is carefuly controlled during manufacture to ensure instant adhesion and a strong air-tight seal with minimal tails.

More than twice the tear resistance means minimum risk of breaks on high speed balers due to abrupt starts or stress at the corners of square bales. 70% higher puncture resistance minimises the risk of perforations from hard stiff crops and damage during handling, stacking and storage. And 35% higher breaking strength guarantees optimum performance thoughout every roll. No down-time getting out of the tractor to re-attach broken film means more bales wrapped per hour, increased output and therefore profit.
