Silage Stretch Films

Silage stretch film provides an effective of airtight cover, one of the most important factors in successful bale silage production. Producing good quality silage is dependent on using good quality materials and equipment, and that includes the bale wrap film. Stretch film bale wrap should meet several key requirements:

  • It should have good mechanical properties
  • It should have a high level of tack
  • It should be stabilised for protection against the damage caused by sunlight, notably UV light

In some European countries good quality bale wrap carry a national ‘quality mark’, like the ‘NF’ mark in France or the ‘SP’ mark in Sweden. These quality labels are issued by independent national testing institutes to guarantee customers benefit from high film quality standards. These include ultra-violet resistance, resistance to perforation, adhesion and dimensional properties such as stretch (55–70%) with even thickness. The specified properties ensure the film performs well in wrapping process and in protecting and conserving the forage.
