Silo and cover films

Optimum protection for your harvest

AGRAVIS offers you a wide range of films for your silos. You will also find the right product for covering land here.

Silage films:

silage films maintain silage quality in the sealed silo. It protects the air-tight underlay film from UV radiation, mechanical stress and the elements. It also reduces air exchange between the silage and the underlay film. AGRAVIS Raiffeisen AG offers you a wide product range for silage films.

ELAN – films for professionals

• Elan three-layer film

The three-layer film from Elan is produced using a special extrusion process (TriEx). During this process, the individual layers are combined into a highly resilient bond with one another in the melt, yet without intermixing with one another. Users can achieve specific mechanical, visual and thermal characteristics which surpass conventional German Agricultural Society (DLG) requirements.

  • Special extrusion process (TriEx)
  • Highly resilient bond between materials without intermixing with one another
  • Comparable with a 200 μ silage film, yet up to a third thinner and lighter
  • Many run lengths to choose from
  • The factory-produced fold in the product (C-fold) enables users to easily unfold and spread the Elan silage film over their silo system from the middle to the longitudinal sides. This ensures that the desired green side is facing upwards after the film is spread.
  • 12-month warranty for weather resistance during normal use.

Polydress

• Polydress O2 Barrier 2-in-1 – combination between silage and underlay films

After the combination film has been laid out, the underlay film absorbs moisture from the ensilage material. This improves firmness, stretching and puncture resistance significantly. The water vapour diffuses through the underlay film and condenses on the silage film, which blocks the vapour. This causes the underlay film to separate from the silage film and nestle against the silo stock’s uneven surface.

  • Six to 10 times better oxygen barrier
  • Film combination can be placed on the silo in a single work step
  • Exceptionally stable, yet also supple
  • The “clinging” underlay film automatically separates from the silage film after a very short period of use
  • 18-month UV stability on the silo

Tips and tricks for stretch films

  • Make optimal settings on balers to achieve high storage densities (at least 220 to 230 kg TM/m3)
  • Keep time period between baling and wrapping short. Wrap bales with film after a maximum of two hours
  • Check wrapping machine on a regular basis: 50 per cent film overlap, 50 to 70 per cent film pre-stretching
  • There should be no adhesive residue on pre-stretching rollers

  • The higher the dry matter and the bulkier the material is, the greater the number of film layers which are required to make things air-tight.
  • Six film layers have proven to be optimum for bale wrapping and eight layers for horse silage.

  • White, light-green film only heats up a little. Light-coloured films are the most gas-tight
  • Dark or black films heat up intensely, increasing their oxygen permeability. Protect against direct sunlight!

  • You must prevent film damage. Tiny holes can cause mould in the entire bale.
  • Do not wrap until the bale is at its storage location if possible

  • Store round bales in an upright position
  • Stack depending on the dry matter content in the silage Three layers are possible if dry matter is more than 45 per cent; stack only two layers if dry matter is less than 45 per cent. If you do not, the lower bales will deform and air may penetrate into the bales between the film layers
  • Lay out the storage facility in such a way that it is not possible to damage the films. If there is a problem with mice, open storage facility with sandy floor; net cover if there is a problem with birds.
  • Check bales for damage on a regular basis

Thermal film XXL is very wide and is used on its own or as a double cover on film that has already been attached. A maximum thermal effect is achieved thanks to the high proportion of thermal additives and especially thanks to the width. This film type can be used as a double cover layer in combination with all film types. If you heat the ground with the thermal film XXL and then lift the black-and-white film at the first stitch, you can regulate the asparagus yield to an optimum extent throughout the season.

The greenhouse effect is increased if you tense the thermal film XXL over frames, creating an air buffer between the bank and the thermal film. This air buffer prevents the ground from cooling at night.

  • 50 µm thick
  • Can be supplied as transparent film
  • Available lengths: 1,000 m; and width: 2 m;
  • also available in transparent thermal pocket film version

Returning old films

Every year, AGRAVIS Raiffeisen AG organises a silage film return and recycling initiative across the region together with its member cooperatives and agricultural centres. Raiffeisen cooperatives thus pursue recycling management objectives and offer farmers a worthy alternative to landfill or incineration.

When are silo films taken for recycling? Where to?

Films are collected at various locations in the AGRAVIS region. Your cooperative or agricultural centre will inform you of the collection date in good time. As you would expect, we’ll also be happy to notify you of the exact date and place of the next collection in your area.

What items may I return?

We only accept silage films without any stretch or wrapping film and free of any cording. The films should be brushed clean, bundled together, and delivered dry, if possible.

Tips on collection

The high proportion of dirt on silage film poses great problems for recycling companies. Wear on shredder blades is excessive and it is expensive to treat cleaning water and dispose of sludge. You as a farmer can help to keep down costs for disposal if you observe the following:

  • Start cleaning and folding the films together in good time since old silage film is accumulated throughout the entire year.
  • If at all possible, collect films from the silo in good weather conditions since they will be easier to clean.
  • Put the films together in bundles as it makes them easier to transport.

What happens to the collected silage films?

AGRAVIS AG arranges for the films that farmers take to collection points to be transported to the film manufacturers. There, they are shredded in a special recycling process, washed thoroughly several times, dried and then melted in an extruder. The recovered re-granulate is used to manufacture new silage films and construction foil, thus closing the recycling loop.
