All about silage wrap

Scope of use

Thanks to its excellent qualities, silage film is used not only in agriculture, although it was originally developed specifically for this consumer. In addition to agriculture, where it is used as a hermetic seal for silage pits and trenches, this type of covering material has found application in other areas of agriculture.

• Shelter for greenhouse and greenhouse premises. Mulching and sterilization of the soil. For silage, packaging for long-term storage of crops. To create a geomembrane.
• The film has found wide application in the construction industry, where it covers building materials, closes door and window openings during construction, reconstruction, repair of premises and buildings.
• The material is used in the cultivation of mushrooms - oyster mushrooms, champignons, honey agarics and other species. In this case, the coating should be of low density.

Peculiarities

Silage foil is a covering material for the hermetic sealing of green forage in silo pits and trenches. Such material is able to protect harvested juicy feed from the external environment.

In order to better ensure fermentation and high-quality fermentation, the developed covering material has modern technical characteristics.

• Manufacturing from primary raw materials gives special strength to the film coating.
• Manufacturers offer a transparent lining type with special characteristics: black-and-white, white-green, black-white-green covering films. The white layer has a high ability to reflect sunlight, the black canvas is absolutely opaque to ultraviolet rays. These indicators provide the best parameters for obtaining high-quality juicy feed. The film is immune to ultraviolet light, but it is capable of transmitting light.
• Manufactured from a light-stabilized base makes it possible to use during long-term storage (up to 12 months). Recent developments have made it possible to use a high-strength polymer (metallocene) in production, resulting in even thinner types. Despite its thinness, this material is able to withstand the fall of a kilogram dart.
• The unique film width, up to 18 m, allows pits and trenches to be covered without unnecessary joints, thus avoiding the risk of air ingress.
• The silage cover protects juicy forage from evaporation, has a reduced gas permeability and does not allow moisture to penetrate inside.
• In the technology of covering silo trenches, three layers are used - lining - thin and transparent, 40 µm thick, black-and-white or black has a thickness of up to 150 µm, lateral - 60–160 µm, they cover the walls and the bottom. The first thin layer fits the surface so tightly that it practically adheres, completely repeating the relief, and 100% cuts off the oxygen access, ensuring the tightness of the closed pit. The second layer is the main one, it completes the sealing of the silo trenches and must have a thickness of at least 120 microns. Optimum is 150 microns. Each layer has its own functional characteristics, so they are not able to replace each other.
• The liner is made of 100% linear low density polyethylene - LLDPE. This is what ensures high elasticity and the ability to tightly fit the surface of harvested silage fodder, completely eliminating the formation of air pockets.
• The covering silage material has excellent elastic properties and increased tear and puncture resistance. Significant reduction in silage losses in vitamin and mineral composition, as well as in nutrients.
• During the production of multilayer silage films, additives are introduced such as:
  • light stabilizers;
  • antistatics, antifogs, infrared absorbers;
  • additives that prevent the appearance of harmful microorganisms.

The advantage of using this type of covering film is its low gas exchange, in comparison with the single-layer type. This makes it possible to achieve high-quality anaerobic fermentation, which has a beneficial effect on the milk production of cattle, poultry egg production and the increase in live weight of poultry and animal livestock.
