Performance HD is suitable for use in any weather conditions and with any kind of crop. Introducing Performance HD 4000, the cutting edge of netwrap technology. Designed to be used in balers with well maintained cutting and tension systems. New techniques in production have brought an innovation called Optima. This innovation will allow Performance HD 4000 netwrap to be as strong as Performance HD 3600, without increasing its weight by any margin. Optima utilises Novatex’s ‘Double Tape’ technology The double tape wide mesh technology is exclusive to Mole Valley Farmers but, crucially, now comes with an enhanced weaving process that increases the netwrap’s and Mole Country Stores, making Performance HD the strongest net available relative strength to weight ratio resulting in the ability to increase the roll length whilst still in the UK market. keeping the strength and weight the same. This brings a huge benefit making life easier when baling with reduced roll changes for the same number of bales, helping to improve on farm efficiencies.

Split bales Splits in film on wrapped bales often expose the forage and usually as a result of insufficient layers of film having been applied to part of the bale. This is confirmed by the fact that they very rarely occur on square bales, where 6 layer application is standard. The usual cause is where a 4 layer application is made, but the wrapper is stopped before the cycle is complete, meaning that part of the bale only received one or two layers. This will either result in a split, or will show itself as a semiopaque strip just ahead of where wrapping stopped.
