Your silage wrapping specialists
Are you looking for high-quality silage plastic that you can rely on? Let’s face it, you want a consistent product with great stretch capability, superior strength and an excellent tack factor. It’s the only way you can ensure your silage bales are maintained, and the silage inside is kept at a high standard.
If you want the very best silage wrap available, make us your first choice. Your baled silage will remain well protected, and our film won’t prematurely degrade under harsh UV conditions. Can you afford to take chances on poor-quality silage wrap? A lot of preparation and time goes into achieving great silage, and the quality of materials used is a huge part of it.
Silage Plastic – the importance of premium raw materials / how it affects silage quality
Our wraps are proudly used in all applications from standard single 55% stretch application to square bales, tube wrappers and high speed aggressive orbital twins requiring 70% stretch such as the McHale machinery. Whatever the application, we have a silage plastic ready to help you in your fodder conservation program.
From covers right through to film for wrapping individual bales, all of our products are manufactured from high-quality raw materials to achieve a high degree of acceptable film behaviour and performance.
The number of layers will affect performance
We supply both 5 and 7 layer constructed film, in which more layers will mean a more uniform thickness of the film and therefore have fewer weak points. The higher the number of layers, up to 7, the less ‘tolerances’ in the specification. This helps to improve parameters such as dart impact, puncture resistance and tear resistance, so this helps improve the overall performance of the film and generally means less downtime for the operator. The other consideration is the quality of the raw materials that go into the recipe to make the silage plastic.
You’ll want to consider the crop type, stretch rate, climate conditions and the type of wrapping machinery to determine which is best for you. The 5-layer film is a more budget-conscious option, so it’s more suited to smaller sizes and less challenging fodder. For larger applications and something a little more heavy-duty, we recommend the 7-layer technology.
So how do we best explain the differences in plastic types?
All 25-micron films are not the same. Yes, the thickness of the films is the same, but the integrity, performance and longevity will depend on the quality of the raw material. For example, a 5-ply film made up of C4 polymers will lose integrity when stretching at 55%. At 70% it will break or spread too thin, creating less of a barrier and less resistance to air-flow permeating through the film. Hence, spoiling silage quicker. If C8 and C10 polymer blends are used, there is more re-enforcement in the structure of the film allowing it to be stretched without compromising the integrity of the film or losing stretch memory.
The idea is to create an effective oxygen barrier that reduces spoilage. Not only does this save you money, because you don’t end up with wasted silage, but it also saves you time. When choosing the wrong type of product that utilizes poor materials, your silage bales are more at risk of puncture, damage or breakdown. Ultimately, this affects the quality of silage, potentially reducing the productivity of your livestock.
In addition, lesser quality silage plastics require maintenance work to ensure the contents don’t completely spoil. This means constantly inspecting the bales and applying repair tape. You’ve got better things to do with your time, which is why we only recommend the highest quality wraps or covers.
Other Quality Indicators of Good Silage Plastic
All our silage film manufacturing partners deal only with the top producers of colourants, UV inhibitors and dispersants. All these factors contribute to making a more consistent behaviour in our silage plastic products throughout. The tackifier used is compatible with the ingredients, so it reacts when it is needed to bond the barriers together and works to minimise tails. When using high tack silage wrap products, it is important to remember that the tack is transparent. So, by the time you witness coloured bands on the top and bottom of the pre-stretch rollers, you know that your rollers are due for a clean.
These dark coloured bands are where dust has stuck to a build-up of tack. This means all the rollers have tack and need cleaning. By the time these “coloured bands” are visible, the film will not be operating as efficiently as it should and can be ‘skimming’ as it travels through these rollers. Symptoms of this are; film going on loose, leaving tails and spiral tearing. Sure, some films will keep operating, but not to their maximum performance. Please regularly clean the rollers with a white spirit cleaner, a brush and a clean rag. This is a good ‘maintenance drill’ that is sometimes overlooked but can contribute massively to better bale quality.
The importance of UV protection
Not everybody has the luxury of keeping silage bales indoors or undercover, and that’s why it’s crucial that your wrapping plastic comes with UV protection. That’s why all of our products are manufactured to the highest standards, and are always adequately UV stabilised. This protects your silage films against premature breakdown, keeping it protected from the elements.
