Sealing and sheeting for silage clamps
As every farmer knows, when it comes to protecting silage and eliminating waste, an air-tight clamp is a safe clamp. Kelvin Cave Ltd have introduced two innovative silage sheeting solutions to UK farmers, both designed to achieve that all-important, oxygen free environment for a good silage fermentation.
Clampfilm™ – the original vacuum film
ClampFilm™ is a cost effective 40 micron primary silage clamp sheet that is spread directly on top of the clamped feed. It is then covered with conventional black plastic and weighted down in the usual way. Any air trapped underneath is used up very quickly by respiration, producing the anaerobic environment essential for making good silage. As the air in the clamp is used up the lightweight, flexible ClampFilm™ is sucked down onto the surface of the silage forming a perfect air-tight seal.
Clampfilm™ is the only such product accredited by DLG (Deutsche Landwirtschafts – Gesellschaft) German Agricultural Society, a leading organisation in the European agricultural and food sectors.
Since it’s introduction to the UK ClampFilm’s tensile strength has been increased, thereby offering even better resistance against damage when being laid or during subsequent handling, adding to it’s ability to give even greater levels of protection against aerobic spoilage – and all at no extra cost!
Even in windy conditions ClampFilm™ can be laid with ease as it settles immediately into the contours and depressions on top of the clamp, and is resilient enough to be walked on as it is being laid and covered.
O2 Barrier 2in1™ is an innovative combination of polyethylene silage film and polyamide vacuum film in a single sheet.
This unique product is only 100µm thick but offers up to ten times less oxygen-permeability, and at least as much strength, as conventional silage clamp sheeting systems – ensuring the rapid formation and sustainability of anaerobic conditions in the clamp.
The silage and adherent vacuum film combination allows quick and easy sheeting of a clamp in one step. Within a short time of being laid the vacuum film absorbs moisture from the silage and separates from the top film, it is then sucked down onto the silage surface, creating an airtight seal.
When the clamp is opened the two sheet layers can be separated completely and can be recycled or disposed of. Being 40% lighter than conventional sheeting systems, recycling and disposal costs are reduced.
To complete the silage clamp-sealing package, and ensure quality throughout the clamp the application of quality side sheets to protect the clamp sides and form a complete seal on the ‘shoulders’, is essential. Available in 50 meter rolls, 4, 5 or 6 meters wide, our 150µm, clear polyethylene side sheets are tough, low-cost and easy to use. The convenient sizes save time when preparing the clamp – no messing about trying to cut sheets to size or battling with last year’s dirty top sheet to try and get ‘a bit more out of it’!
We have a very simple but highly effective way of making an O2 Barrier 2in1 covered clamp really airtight as detailed here.
