As every farmer knows, when it comes to protecting silage and eliminating waste, an air-tight clamp is a safe clamp.

This hasn’t always been easy to achieve. On its own, traditional black plastic is too inflexible and oxygen-permeable to create a perfect seal so air pockets remain, forming the right conditions for composting and rotting to take hold around the top and shoulders of the clamp. This soon spreads, and it is not uncommon for as much as 10% of silage in a clamp to be lost!

Now, ClampFilm™, from Kelvin Cave Ltd, the home grown feed preservation and processing specialist, provides a simple, efficient and cost effective way of sealing a clamp that effectively “vacuum packs” the feed thus eliminating spoilage, preserving quality and protecting your profits.

ClampFilm™ is a 40 micron primary silage 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 ideal 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's tensile strength has also 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.
